Why Install a Marine Electric Toilet on Your Pleasure Boat

Let the best electric toilets decorate your boat as they are loaded with multiple features. The electric toilets have various advantages which make them even more attractive. These toilets exhaust less amount of water which is an effective way of conserving the rapidly depleting resource. Also, low water usage does not decrease the efficiency with which the materials are flushed. These electric toilets do not consume much power and also produce less noise. Certain toilets are even outfitted with a solar panel for power saving functionality. Besides having these qualities, the toilets are very much user friendly and can be maintained pretty easily. The most important characteristic of electric toilets is that it furnishes service for many years, that too in difficult circumstances.

The electric marine toilets permit the water to get stored in the bowl. These toilets also help in the development of a water seal which prevents odors from entering the main compartment through pipes and storage tanks. If consuming less fresh water is the objective, then these toilets are of great benefit. While on board, marine water can be utilized for flushing thus helping in the storage of fresh water. The electric toilets for boats have been aided with such functionality so as to conserve fresh water. Such a feature permits the consumption of fresh water only when there is abundance of it such as in the dock. The boats offer both the options to the user to either utilize natural or marine water for flushing purposes. However, the advantage of using fresh water is that it helps in retaining the odor of aquatic organic composites.

Electric Toilet Protect Our Environment

The electric marine toilets have been have been manufactured in such a way that they abide by the regulations set up in order to protect our environment. These toilets come with customer services for help and other enquiries. The users may take assistance for the products as long as they are functional. Customers can seek help of our technical staffs as well. They can easily be contacted without any difficulty. The products can be requested online and are generally shipped within a day or two.

It really IS possible to have a completely odor-free system!

You’ve probably read or heard, over and over again, that the key to odor control is the “right” hose, that the “wrong” hose permeates with sewage and causes the system to stink.  That’s folklore…a little truth coupled with a lot of misunderstanding.  The real key to odor control is in knowing how to incorporate proven sewage management principles—the same ones used in composting and sewage treatment—into the installation of the entire system.  What very few people in the marine industry have learned, and why there is so much folklore about odor, is the very nature of sewage itself and how it breaks down, what creates odor and what prevents odor from forming.  Once we understood these principles and learned how to apply them to onboard systems, we were able to install systems that are completely odor-free and correct the ones that weren’t.  Once you understand it—and it’s so simple!—you can do the same thing.

Marine Holding Tank Odor Solutions

There are two ways to deal with marine holding tank odor: try to reduce it, mask it and contain it after it’s formed, by using chemicals and filters—which has never proven very successful…or prevent odor from forming in the first place.

Sewage contains both aerobic (needs oxygen) and anaerobic bacteria (functions in an airless environment); neither can function in the other’s environment.  Why is that important?  Because  only the anaerobic bacteria in sewage  produce foul-smelling gasses!  Aerobic bacteria break sewage down, as does anaerobic bacteria—but aerobic bacteria do not generate odor.  So as long as there is a sufficient supply of air to the tank and an aerobic bacteria treatment is added to aid that which naturally occurs in sewage, the aerobic bacteria thrive and overpower the anaerobic bacteria and the system remains odor free.

A bio-active (Iive aerobic bacteria) holding tank treatment, such as our own “K.O.”, works with the aerobic bacteria in sewage, eliminating odor, completely emulsifying solids and paper and preventing sludge from forming.  Enzymes do little if anything—a brief respite from odor immediately after adding them, then odor begins to build again.  Chemical products mask odor with another odor and they kill not only odor-causing anaerobic bacteria, but beneficial aerobic bacteria as well—not good, because the aerobic bacteria are needed in the system to break down and emulsify solids and paper.  Otherwise, they only break UP and dissolve them into little tiny particles that settle to the bottom of the tank, along with chemical residue, to become sludge that turns to concrete.  Chemicals, unlike bio-active products, are also unwelcome in landside sewage treatment facilities and are especially unappreciated by those living and working near them!

The bacteria in sewage produce a variety of sulfur monoxides and dioxides (which are the malodorous gasses), methane—which has no odor but is flammable—and carbon dioxide, which also has no odor but creates the environment in which the aerobic bacteria cannot function but allows the anaerobic bacteria to thrive.  Carbon dioxide does not rise or fall, it is ambient—like the atmosphere, but heavier than air.  Without a sufficient flow of fresh air through the tank to allow it to dissipate, it simply lies like a blanket on top of any pool of sewage (whether inside hose or a holding tank) and builds, suffocating the aerobic bacteria and creating the perfect environment for the anaerobic bacteria to take over.  The system literally “turns septic” and the result: a stinking boat…or at least foul gasses out the vent line every time the head is flushed.

Importance of Discharge Hoses in Marine Holding Tanks

To prevent this, let’s start with the head:  the discharge hose, no matter whether it goes overboard, to a Type I or II MSD, or to a holding tank, should be installed, if at all possible, with no sags or low places where sewage can stand. When a marine head is not flushed sufficiently to clear the hose of sewage and rinse the hose behind the sewage, that sewage sits in low spots in the hose or bits of it cling to the walls of the hose—getting no air, allowing the anaerobic bacteria to thrive and produce their stinking gasses.  If sewage stands in a low spot which gets no air in hose which is susceptible to a high rate of water absorption, it will permeate the hose.  This is what has given rise to the myth that the “wrong” hose causes odor. Therefore, it’s important to flush your head thoroughly enough to clear the entire hose of sewage and rinse behind it.  And when you leave your boat to go home, flush the head thoroughly one last time, this time with fresh water.  Until marine holding tanks came along, the hose was the source of most odor, but incomplete flushing was the real cause.

Marine Toilet Expert Has the Answer to Minimize Running Aground

Raritan Engineering Company your marine toilet specialists would like to share with you these topics we thought would be of interest to you this month regarding why it is so important not to panic if you run aground. 

Running Aground

Your marine toilet expert knows that despite all efforts to stay off shoals, beaches, or rocks, groundings do happen. It is said that there are only three kinds of skippers, those who have run aground, those who will run aground, and those that have but won’t admit it.

Immediate Actions

First, Raritan marine toilet experts say that here is what you should not do when you run aground. Unless you are absolutely sure that it is a small shoal with deeper water ahead, do not apply power and try to push your way across, you will only put yourself harder aground.

Your boat toilets expert knows that instead, take time to assess the situation. Is any water coming into the hull? Where exactly are you? How did you get there? Where might deeper water lie? What is the state of the tide?

You can find more information as well as get assistance on boat toilets and on how not to panic if you run aground at Raritan Engineering.

Marine Toilet Professional Continues Discussion on Building Your Situation Assessment Skills

Possibly the best marine toilet expert says, let’s assume that you are lucky and that the tide is rising and that the increased depths will be enough to float you free. Although you might get off sooner if another vessel pulled, letting the tide float you off is less stressful on your hull and your crew.

If you are less lucky, and the tide is falling, quickly assess the situation and the possibility of refloating the boat before the tide goes down further. If this is not possible, determine how far it will go down.

Getting Off

If you are only lightly stranded, you may be able to get off without assistance. First, determine where deeper water lies, this may or may not be the direction from which you came.

You might also place some heavy gear in a dinghy. Marine porta potty specialist, says that on a sailboat, you can try reducing draft by taking a halyard out to one side, attaching it to an anchor or another boat, and pulling. Yet another maneuver is to put out an anchor in the direction in which you wish to move.

If a pull is made, keep all persons away from the line and beyond the ends of the line in both directions. Various types of lines stretch to different degrees, but all stretch enough to act as slingshots if they break or if fittings pull out.

Even if the other boat cannot pull to get you off, she may help by running back and forth and making as large a wake as possible. The waves formed in this wake may lift your boat enough to get her off.

I would encourage any boater to join one of the commercial towing organizations. However, you should check with other boaters in your area for recommendations as to which one to join.

So don’t forget these helpful pointers to avoid panicking if you run aground. 1) Do not apply power and try to push your way across;  2) assess your situation and find out exactly where you are;  and 3) determine where deeper water lies and see where you might have came from.

Marine Hardware Expert Says Don’t Get Rid of Your Compass Yet

Raritan Engineering Company your marine hardware specialists would like to share with you these topics we thought would be of interest to you this month regarding how to boost your compass skills.

Your marine hardware experts say let’s begin with a piece of advice: Don’t cast your compass to Neptune-it’s not dead yet! Of all the navigational tools and instruments employed on boats, the compass is still the single most valuable. Its sole moving part is governed by a fundamental physical force of Earth itself.

Why, in this world of GPS and other networked marvels, is that so important? Isn’t it enough to know where the boat’s going, and isn’t that the same thing?

Well, no. Where the boat’s pointed and where it’s going aren’t always the same. In fact, they rarely are. A current will cause a boat to move over the ground in a direction different from that in which the boat is pointed.

Let’s take our compass away for a moment and steer the boat toward a GPS waypoint by matching course over the ground (COG) to the bearing to the waypoint. We’re doing well, and the track on the plotter shows our course as a straight line with the waypoint dead ahead.

If we’d had our compass, we’d have known, from the bearing information provided by the GPS, where exactly to look for the mark, and we wouldn’t now be facing a charge of damaging government property.

No matter what vehicle we’re steering, a fixed reference of some kind is an essential aid to pointing it in the desired direction.

Your marine hardware specialists know that while the compass can’t tell us where we’re going, it can tell us what direction we’re steering, which makes it unique. And far from being made redundant by electronic devices, the compass adds to their value. For example, by comparing COG from our GPS to the course steered by the compass, we can detect the presence of a crosscurrent.

Go to http://www.raritaneng.com and see how you can find more information as well as get assistance on marine hardware and on improving your compass using skills at Raritan Engineering.

Adjusting the Compass
A magnetic compass, as long as it’s in good physical order, will always point in accordance to the magnetic field surrounding it. If that field was the Earth’s alone, it would be utterly reliable, but the compass isn’t monogamous, and it’s easily led astray. Onboard magnetic influences-such as those created in some electrical devices and by iron-cause a compass to point askew from magnetic north, an error called deviation.

A professional compass adjustor will “swing” the compass by checking it against known references, such as a proven range or ranges on structures or geographic features. Once on the range, he’ll have the boat slowly motor along the cardinal directions-north, south, east, and west-as indicated by the boat’s compass while he reads the bearing on the range with a pelorus.

Posted at the navigation station, the deviation card allows the navigator to convert a course laid on a chart to a course to steer. Conversely, it allows him to correct a bearing taken by the ship’s compass on a landmark to a magnetic bearing.

Once the ship’s principal compass has been swung and adjusted, have the adjustor also swing and make up a deviation card for any other compass that might be used for navigation, including the one that supplies heading data to the autopilot.

Deviation by GPS

Prior to the widespread use of GPS, you took compass bearings off recognized features in the landscape and plotted them on a chart to figure out where you were.

Because your GPS knows where it is, it can also calculate where it is in relation to any other location in terms of range (distance off) and bearing.

Create a waypoint in your GPS with the coordinates of an accurately charted and identifiable feature, say a lighthouse. Set the waypoint as your destination and steer toward it. The farther you are from the waypoint the better, but a couple of miles provides sufficient accuracy.

Some sailboats and a good many powerboats have two helm stations, each with a compass. Only one of these can be the master compass, so you have to designate one. On a sailboat, this would probably be the one you use when motoring.

Another issue is parallax. This arises when a boat’s steering station is off-center or, on a sailboat, when you steer from the side of the cockpit. If you’re standing behind the starboard helm station and looking over the bow, you’re not sighting down the boat’s centerline. If you aim the bow toward a mark, the boat won’t be heading toward that mark.

So don’t forget these helpful points on how to improve the use of your compass. 1) Keep in mind the movement of the current;  2) create a waypoint in your GPS;  and 3) keep in mind parallax.

Marine Toilet Analysts Show How to Maneuver at Night

Raritan Engineering Company your marine toilet specialists would like to share with you these topics we thought would be of interest to you this month regarding how to maneuver your boat safely at night.
 
Your marine toilet experts know that once darkness creeps across the water as the glow of the sun fades below the western horizon.

Yet, nighttime navigators need not bite their nails. With the right equipment and decent weather, a night cruise can be safe, enjoyable, adventurous and even romantic.

Fortunately, there are more tools than ever to enhance or supplant our vision when navigating at night. GPS/chart plotters, detailed electronic cartography, advanced radar, thermal imaging, night-vision scopes and spotlights not only increase the safety factor but also inspire enough confidence to enjoy boating after dark.

Slow and Easy

The first rule of night boating is to slow down, no matter what high-tech navigation equipment you have on board. Even on a moonlit evening, you just can’t see as well as during the day.

Your marine toilet experts say that the best speed on any given night depends on visibility. During a full moon, you might feel comfortable running the boat a bit faster than you would on a night when everything fades to black.

Go to http://raritaneng.com/catagory-pages/choosing-your-marine-toilet/ and see how you can find more information as well as get assistance on marine toilet and on how to maneuver your boat at night at Raritan Engineering.

Mood Lighting

Onboard lighting is a tricky thing when navigating at night. You need backlighting to see your instruments and electronics, and an overhead light to read a chart.

Yet once your eyes have acclimated to the dark, too much onboard light can destroy your night vision. Once this occurs, your eyes will need to readjust:

With this in mind, most marine electronics allow you to adjust the brightness of the backlighting, and many units also have a “night mode” with a darker background to keep illumination levels to a minimum.

When it comes to instrument illumination, red is the best color since it doesn’t desensitize the rods. Most newer instruments are equipped with dimmers to adjust the intensity of backlighting and preserve night vision. If yours isn’t, a dimmer switch can be wired in for control.

Wherefore Art Thou?

Should your date paraphrase the classic Shakespearean question “Wherefore art thou, captain?” you should be able to point to your GPS/chart plotter and answer “right here.”

Thanks to detailed electronic cartography from C-Map (c-map.com), Navionics (navionics.com) and others, today’s chart plotters show a lot more than just your present position.

“You set a minimum draft such as six feet and set a look-ahead distance such as a quarter-mile,” says C-Map’s Ken Cirillo. “Then the plotter looks at all possible obstructions, as well as shoals, in a searchlight pattern and alerts you to danger.”

Of course, a depth sounder is also important for confirming the water depth. Whether cruising at night or during the day, you should not rely solely on the electronic chart, particularly if the chart has not been updated recently.

Radar Love

Seeing everything that’s around you at night makes you feel more confident while cruising, and that’s just what radar (radio detection and ranging) is: your sight when your eyes are blind.It shows you what’s out there and tells you how far away it is.

While a chart plotter shows fixed objects, radar can show you just about everything above the water’s surface, including other boats. Traditionally, radar loses effectiveness at very close range due to a phenomenon called “main bang,” which results in a blob in the middle of the screen that obscures targets close to the boat.

Most multifunction displays, such as the Furuno NavNet system, can also be configured to “overlay” the radar readings on an electronic chart display.

Light Up the Night

Boats don’t have brakes. Know what? They don’t have headlights either. And with good reason. In open water, the light reflecting off waves and mist is often more blinding than beneficial at night.

However, there are occasions when a searchlight or spotlight is handy, particularly if you are trying to locate or identify a nearby object such as an unlit boat, buoy, shoreline or jetty.

Fixed-mounts are nice on bigger boats, while handhelds lend themselves to smaller boats. Whichever you choose, try to use the light sparingly and briefly, particularly if there are other boaters in the immediate vicinity.

Docking lights are another option, usually flush-mounted just below the rub rail on both sides of the bow. Yet, they are designed for use only in close-quarters situations such as when pulling into a slip at night.

Scope Things Out

You can also buy night vision — a technology that amplifies light through a scope. This lets you see as if it were daytime, though everything’s cast in green.

An affordable night-vision device is the NVD mini scope from Minox (minox.com, $299). Measuring just 5½ inches long and 2 inches in diameter, this rechargeable scope not only amplifies available light, but also beams infrared light.

Learn the Lights

The U.S. Coast Guard has long-established light display standards for nighttime navigation, and these apply to both vessels and navaids such as channel markers.

If you do much night boating, knowing the meaning of lights is essential and might save your boat and your life. For example, you see two vessels in the distance and they’re a few hundred yards apart. So to save time, you think about cutting between the two.

Eyes and Ears

In the end, the most valuable navigation tool is a sharp eye. And the more, the better when darkness falls. There should be two pairs of eyes (and ears, since sound travels well on the water) on the bridge at night.

Also, with two lookouts, it is less likely that either will fall asleep on the bridge. This is a real issue, particularly on long night passages while using autopilot and sitting in a comfortable helm chair.

Having that someone special on the bridge at night might keep you from falling asleep, but it can distract from maintaining a lookout..

So don’t forget these helpful pointers on how to maneuver your boat at night. 1) Take it slow and easy;  2) proper lighting;  3) scope things out and 4) use your eyes and ears.

Raritan Engineering of Millville, NJ has recently launched a macerator pump with a new design through a video which can be watched on YouTube. The revolutionary design reduces 99.9% of any waste matter spillage. 

Raritan Engineering manufactures equipment for pleasure boats throughout the world. Its products include marine toilets, waste treatment systems, icemakers,sanitation materials, and water heaters. The company designs products that help maintain an environmental balance and ensure the quality of marine sea life. Products such as macerator pumps allow Raritan to do its part in preserving sea life. The product is made to empty holding tanks in boats’ toilets to which allows safe waste discharge and management. Raritan representative Joe explains: “For starters, a macerator pump is designed for a boat’s toilet to empty the holding tank on a boat. Holding tanks are installed on toilets, and their job basically is to hold waste until boats can discharge it into a dockside pump, facility,” said Joe. “Macerator pumps are responsible for emptying holding tanks effectively–they include a bronze cutter to grind waste down to its smallest size, allowing efficient waste management. This means it guarantees an easier discharge, and boaters can be sure that they are adhering to proper environmental standards.

“The macerator pump’s new design comes with a wastewater valve, which allows for pump maintenance with no spillage, it is a direct replacement of competitive units, which eliminates waste. The video explains the pump’s features and key improvements. Raritan Engineering’s design allows users to remove the pump without disconnecting plumbing. Another feature is easy maintenance, as owners can simply shut off the valve and remove the screws. In addition, the macerator pump is made from stainless steel bolts to avoid corrosion. A spring-loaded Viton shaft seal is also used to prevent leaks, and a proprietary rubber impeller compound allows longer dry running time. An optional Smart Macerator Control monitors the motor and pump to prevent dry run overload.

Raritan Engineering is currently developing more products that will help promote sanitation and effective waste management systems for boats. The company is driven to keep marine sea life safe, as well as in helping customers find more ways and solutions to make sure installations are fully in line with local regulations concerning discharge.

Marine Ice Makers Specialist Helps You to Get Your Boat Around Bridges 

Marine Ice Makers Specialist Explains How to Have a Pleasant Experience While Moving Around Bridges 

Raritan Engineering Company your marine ice makers professionals would like to share with you these topics we thought would be of interest to you this month regarding how to move your boat around bridges. 

Your marine ice makers experts know that traveling the inland waterways can be a pleasant experience but can also bring some special challenges especially for larger boats and sailboats. Dealing with draw bridges takes some knowledge of how the system works and knowing what you are looking for, especially at night.

Nautical charts only tell you that there is a bridge and what the horizontal clearance (width) and vertical clearance (height) are, says your specialist of ice makers for boats. The vertical clearance is the one you are probably going to be most concerned with, i.e. will you fit under the bridge or will you have to open it?

You should consult your chart for the note on heights; most will show minimum vertical clearance at mean high water. That means if you are at the bridge at any time other than high tide, you should have more clearance than shown. (You’ll be able to tell exactly when you get there.)

Your marine parts depot specialists know that as you approach a bridge there are several thing that you should look for. You should check the right side of the bridge opening for the “clearance board”. Your ice maker replacement experts know that this will give you the minimum clearance, in feet, from the water level to the bridge structure.

You can find more information as well as get assistance on marine parts depot and on how to move your boat around bridges at Raritan Engineering.

Other things to look for as you approach the bridge is a blue sign with what looks like a telephone receiver with a lightning bolt through it. This will give you the radio frequencies that the bridge monitors (usually 16 and 13 or 9). It is customary, at least in most areas, to contact the bridge tender by VHF radio to request an opening, however, there is a sound signal that can be used.

Marine Ice Makers Expert Wants to Help You Do Your “Bridge Homework”

Another piece of information on the bridge will be its name. If you didn’t do your homework when you planned the trip you will need to know that name to call the bridge. It is not specific enough to just call out “bridge, bridge, bridge.”

On the bridge you will also find a white sign that shows the hours of operation and special operational procedures. You should note that some bridges open on demand year-round and some only open on demand during certain parts of the year.

You may also find regulatory signs on bridges with information on speed limits or other warnings. In many cases speed limits may change at a bridge so be careful to heed these regulatory signs. Marine ice makers for sales analyst know that the bridge structure makes a great place to set up a marine speed trap.

While waiting for the bridge to open be aware of your position and make sure that current is not carrying you into the bridge. I remember sitting behind a sailboat a few years ago waiting for the bridge to open. I guess the skipper of the sailboat took the opportunity to go below for some reason.

Once the bridge is open proceed through with caution. Many times, if there is wind or current, you may find your steering affected. Keep a close eye out and try to anticipate any corrections that need to be made.

So don’t forget these helpful tips on how to move your boat around bridges. 1) Dealing with draw bridges takes some knowledge of how the system works and knowing what you are looking for, especially at night;  2) Other things to look for as you approach the bridge is a blue sign with what looks like a telephone receiver with a lightning bolt through it;  and 3) While waiting for the bridge to open be aware of your position and make sure that current is not carrying you into the bridge.

Experts at Your Marine Parts Depot Show How to Be A Small Space Guru

Raritan Engineering Company your marine parts depot specialists would like to share with you these topics we thought would be of interest to you this month regarding how to become a guru of moving your boat in small spaces.

Your marine parts depot says, my home dock, assigned by my friend, the local Harbour Master, has, by virtue of its difficulty, made me a better boater. I have no choice but to try to hone my skills on every docking. The ‘HM’ expresses no interest in my anxiety level (or my crew’s), nor in how many close calls we have had — as long as I actually can get in and out, then he is happy, and for the finesse which this has added to my technique I am grateful.

Step number two: the next, and probably least significant conundrum of this docking entails that first turn to port, to head more or less north, between the two rows of docked boats. The prevailing wind tends to push the boat through a much wider arc than available space permits. We overcome this using the same techniques as for the more exacting maneuvers coming up in a few moments. 

The boat must go very slowly, often coasting, more rarely even using reverse gear to take off headway. Slower speeds allow sharper turns. Start the turn early, knowing that the boat slides and skids as it yaws

Go to http://raritaneng.com/catagory-pages/replacement-parts and see how your marine parts depot specialists know that now that you have slowed down and are about to make the turn, you may need to give the boat a little shove, with the wheel hard over, using more engine power than available at just idle speed. The extra power gives you ‘steering authority’.

Step number three: Back off on the power as soon as possible, and make your way between the two rows of boats. You may have to over-rotate, sometimes by a surprising amount, to compensate for the gradually dissipating momentum which wants to make the boat skid wide through the turn, and to counteract the force of the wind, which is now more or less abeam.

You can find more information as well as get assistance on marine parts depot and on how to move your boat in small spaces at Raritan Engineering.

Step number four: The next corner to negotiate is just the same as the first, except worse. Quarters are getting closer, and a novice or unskilled boater may, even though he felt comfortable making the first turn, now experience unease, even though the general principles have not changed.

My boat’s stern swings to port, in reverse gear, due to ‘asymmetric propeller thrust’. A minority of boats have sterns which swing to starboard. The phenomenon goes by several names, one of which is ‘walking’.

Step number five: By this stage, I need not say that getting through a narrow gap, and then turning the boat sharply into its deep alcove, with many other boats tied up nearby, and the wind howling, is not a trivial exercise.

Three final points: (i) There is quite often a point of no return, a place beyond which there is no practical way to go into reverse gear and back out into open water. Close quarters, wind, reverse gear — these can be an impossible combination.

Conclusion — Close quarters maneuvering has no conclusion. I find this docking easier in October than I did in May, and I hope and expect to find it easier in ten years than I do now. It’s never perfect, and I’m always learning.
