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 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.

So don’t forget these helpful tips on how to move your boat in small spaces. 1) first turn to port, to head more or less north, between the two rows of docked boats;  and 2) 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.

Your Marine Holding Tanks Expert Shares Time-Tested Customs and Traditions

Raritan Engineering Company your marine holding tanks specialists would like to share with you these topics we thought would be of interest to you this month regarding boating etiquette.

Boating Etiquette

Your marine holding tanks experts know that boating, as a recreational sport, has been around for over 300 years. During this time many customs and traditions have been developed in order to help relieve the natural stress that comes with dealing with the elements. No matter how long you have been boating there is always that tense feeling when you are out there on your own.


Obviously, the rules of the road are going to dictate how you operate your vessel underway in order to prevent collision, says several west marine holding tanks experts. But what if no risk of collision exists, are you then free to do whatever you want when operating in the vicinity of other vessels? Above all, remember that you are responsible for you own wake and any damage done by it.

When overtaking a slower vessel in open water, do so with as much room as depth conditions allow and slow your speed, if necessary, to avoid rocking the other vessel. There is nothing worse than being below in a slow trawler or sail boat, cooking breakfast, and being suddenly overtaken in close quarters by a loud, wake-throwing, go-fast boater. Especially if the wake causes the hot bacon grease and coffee to be thrown around the galley.

Anchoring and Mooring

Your marine sanitation device experts know that to be sure to enter an anchorage or mooring area at a slow speed. This is like moving into a new neighborhood. You want your neighbors to like you. Again, you don’t want to create a wake that would upset someone’s dinner or drink.

The marine holding tank systems professional knows that you need to remember that the first person in the anchorage has the right to determine the swing radius. Don’t get too close to other anchored boats. The wind can change and in a matter of minutes you can have fouled and tangled anchor lines, and hulls and dinghies banging against each other. I’ll never forget the commotion caused one night off the Bitter End in the BVI when a late-arriving boat anchored too close to another.

Your Marine Holding Tanks Specialist Has Other Great Tips to Keep in Mind

Before anchoring evaluate your intended behavior; the more music, people on board, children, pets and smoke from your barbecue that you intend to create, the further downwind you should be from your neighbors.

You can find more information as well as get assistance on marine sanitation device and on boating etiquette at Raritan Engineering.

If you are using your dinghy at night to go to shore or visit others in the anchorage, do so using oars and not your outboard. How far could the shore be if you’re anchored in ten feet of water? Some boaters are friendly and like to socialize, while others are reflective and just want to be left alone.

Marina Manners

When you stop for fuel, keep in mind that other boats may be waiting to get to the fuel dock. Do not leave your boat to pick up groceries or hang out in the bait shop. Tie up securely, follow proper fueling procedures, pay the bill and move away to another docking area or guest slip if you need to do other business ashore.

If you are already safely docked in the marina and there is no dockmaster or helper around to assist boaters as they dock and undock, your boat holding tanks specialists knows that it is courteous to assist others in your vicinity with their lines.

Tips For On Board Guests

Whenever you invite guests aboard for the day, a weekend or an extended cruise, you should explain to them in advance what is expected of them, especially if they are not experienced boaters.

When quests arrive, assign a locker to each where they may stow their gear and make clear that everything should be kept in its assigned place. It could be dangerous or impair the operation of your boat to have clothing and other gear floating around loose.

Familiarize your guests with safety and emergency procedures before leaving the dock. Explain fueling procedures, docking and undocking plans, etc.

By being up front, honest and direct with your guests everyone onboard will have a safe and more pleasurable trip.

So don’t forget these helpful pointers on maintaining good boat etiquette. 1) Remember that you are responsible for you own wake and any damage done by it;  2) you want your neighbors to like you;  and 3) it is courteous to assist others in your vicinity with their lines.

Macerating Toilets vs. Vacuum Marine Toilets Part 2

Macerating Toilets Prevent Odors From Sewage Tank Coming Back Thru Toilet Bowl

All plumbing code for house requires a J trap under the toilet to prevent gases from sewage main to come back thru toilet. Boat building industry has no such requirements.

Vacuum toilets have no water seal. It mostly depends on vacuum (negative pressure) to prevent gases/odors coming back to toilet. In case of vacuum pump being turned off or not working, there is a direct connection between holding tank and toilet without any water seal. There is a valve between hose and toilet bowl and seal on the valve compromised with loss of vacuum.

Macerating toilet, with vented loop has a water seal just like home and seal is reliable even during short term and long term storage.

Low noise

There is a myth that macerating toilets are noisy. Myth has been established by use of rubber impeller in older design macerators. Even macerators to empty out holding tanks and fish boxes use rubber impeller and are noisy.

However almost all manufactures of macerating toilets use centrifugal design for discharge pump. These designs are quieter and make only gurgling sound when runs out of water.

Vacuum toilets are famous for load popping noise. Some customers have described this noise as bullet shooting thru pipe. There are several You Tube videos making fun of vacuum toilet noise on web.

All vacuum toilets and some macerating toilets Marine Toilet require pressurized water for flush water. User should also consider noise generated by diaphragm pump for pressurized water due to toilet system.

Minimum water consumption

It is true that vacuum technique requires less water to evacuate the bowl compared to older style macerator toilets. However water needed to rinse the bowl should also be considered. New control strategies to turn discharge pump and inlet flush water as needed has reduced water consumption in macerating toilets to as low as vacuum toilets.

Minimum power consumption

Power used is measured by amps multiplied by time pump is on.

Vacuum toilet, for example may only draw 6amps. Considering that it runs for 45 seconds, power draw is equal to 6 x 45 =270 amps-sec.

A macerator pump draws 10 amps for 10 seconds. Power draw is 10 x 10 = 100 amps-sec.

Both cases do not consider power required to maintain pressurized water.

Macerator equipped with seawater pump may have a power draw of 18 x 10 = 180 amps-sec, still lower than vacuum toilets.


Vacuum toilet has several components to the system: Toilet, Vacuum generator and holding tank. Components have to be plumbed with leak free joints. There are limitations as to how high vacuum generator can be from the toilet. For boat builders installation requires careful planning. For aftermarket installation a factory certified installer is needed.

Macerator toilets only require installation of one component. Toilet itself is self contained with pumps and control. Only two hoses, discharge and inlet has to be plumbed to toilet. Wiring is also simplified by pre wiring all controls at factory. User only needs to connect to positive and negative at the toilet. Most macerating toilets can be installed by do it yourselfers.


Vacuum toilets function depends on vacuum switch reliability, valve seals, and leaks. Finding a vacuum leak could be a difficult task. Most problems on vacuum system may require a visit from certified technician.

Macerating toilets requires troubleshooting on control. Replacing component of control is easy. Discharge pumps are reliable and seldom needs maintenance.

Raritan Engineering Company your marine products professionals want to show you these topics we assumed would be of passion to you this month concerning watercraft docking tips.

Your marine products experts recognize that we can not cover every little thing concerning boat docking in one sitting, however I assume you’ll be stunned at the amount of the standard concepts of close quarters handling are symbolized in the example docking which I will certainly be going over quickly.

That brings up one more important factor. Learning how to marine dock is done on the water, in our watercrafts, not by reviewing it below. Reserve understanding and great training are essential, (I would certainly state critical), as well as enable us to concentrate our minds quicker and accurately compared to merely by utilizing the hit and miss approach.

Port-side-to– a docking dissected

For today functions, I’m visiting presume tranquil marine conditions, as well as not aspect in the effects of wind. Wind is possibly the hardest point to emulate, when docking a boat.

Just what’s your angle?

Go here to see how your marine ice makers professionals understand that the very first thing to discover is that this seafarer is being available in at an angle. This makes it a lot easier to go for a particular spot, and to bring the watercraft in near the dock without scuffing.

You can find more details as well as get aid on marine ice makers and also on boat docking suggestions at Raritan Engineering.

Marine Products Professional Sees the Importance of Learning to Dock Your Boat

Coasting as well as the power turn

Secondly, think of what throttle setting you would certainly utilize at the start of the technique. Nevertheless, drifting is when “steerage”, the ability to steer, goes to its minimum, since either i) there is no discharge current from the prop to enhance the impact of the tail, or ii) with inboard/outboards, many of the guiding “authority” merely fades away when the transmission remains in neutral.

Keep up the energy

The following thing the seafarer will do, as the dock attracts nearer, is to begin to transform the boat. Nonetheless, this is likewise concerning the moment that he or she wishes to decelerate to a quit, backwards gear. While slowing down, the vessel might be tough to guide.

Thankfully, watercrafts in activity have energy: once moving, they tend to proceed moving, and once turning, they often remain to transform. This often confuses the much less skillful skipper, but momentum is precisely what to make use of when all various other steering alternatives fall short, also for products acquiring experts. At merely exactly what point to turn, as well as just how hard as well as for how long, I can not say.

A walk on the dock

One last point: it is very common for propellers to drive asymmetrically, a lot more on one side than the other, and also in some boats the effect is often specifically strong in reverse equipment. The appropriate marine products are likewise required to enjoy your taking a trip.

It’s due to this result that we are reviewing especially port-side-to docking. Right-hand man propellers stroll the stern to port, backwards (a minority of propellers are “left hand” – for them, this entire discussion is a mirror picture).


There is no final thought to watercraft docking or in buying the best products. I have yet to listen to the last word, as well as I’ve probably talked about as well as researched it greater than most. Even if this port-side-to docking were all there was to know (as well as it’s not, it’s simply the barest start), one could possibly still spend a lifetime sharpening and refining the skills and strategies it needs.

Don’t neglect these practical points on discovering how to dock your boat. 1) Know your angle; 2) understand ways to deal with cruising and also the power turn; 3) maintain the momentum; and also 4) the stroll in the dock.

“You Need to Get yourself ready for bad weather conditions”, Says Marine Hot Water Heater Professional

Raritan Engineering Company your marine water heater experts wish to show to you these subjects we thought would certainly be of interest to you this month concerning the best ways to handle your boat in challenging weather condition.

Today’s tip from your marine hot water heater experts is about preparing on your own for hefty climate. If you have actually kept a correct hunt, created a “eagle eye” and also checked the weather condition on your VHF radio, you should have lots of time to get prepared.

The complying with checklist was gathered from various sources, your seaward marine water heater experts as well as from input from those who answered recently’s inquiry concerning “just what to do if hefty climate is approaching.”.

Go to and see related information on marine sanitation devices.

Boat Water Heater Experts Say This Is What Every Skipper Should Know

  • Determine arrival of tornado, wind direction, speed and estimate time to your location.
  • Close all hatches; close all ports and also windows. (Keep the water on the exterior.).
  • Pump bilges drying and repeat as needed. This assists do away with “cost-free water impact”, claims west marine hot water heaters analysts. (Sloshing of water in the bilge as the boat rolls which can impact security.)
  •  Set emergency situation devices that you might need such as hand pumps, bailers, initially aide kit, sound signaling tool, and so on.
  • Get a good layout of your position and also plot it on your graph. Make note of the time, your heading and also rate.
  • Make strategies to change program to sheltered waters ideally.
  • Protect against getting caught in bad weather condition by creating a “eagle eye,” paying attention to your radio, and going to coast prior to it becomes an emergency situation.

Marine Water Heater Specialist Recommends Developing a “Weather Eye” to Avoid Getting Caught in Heavy Weather

Jack Lines – lines rigged along the outboard decks ranging from the bow aft. This enables you to affix the secure from your harness and progress and back at will.

Harness – a nylon internet harness put on in rough seas or hefty climate. It has a secure with a clip. Marine hot water heater installation companies says that the clip is affixed to the jack lines or lifelines so that if you are washed too far in a tornado you are still affixed to the boat.

Sea Anchor – A floating canvas cone, held open by cable rings, with an opening in the smaller end, and a rope bridle at the larger end affixed to a line leading to the bow of the boat. It is utilized in storm problems to (a) maintain the bow of the boat into the wind, as well as (b) slow the downwind drift of the boat.

So always remember these useful points on how you can handle your boat in difficult weather condition. 1) Determine location of storm, wind direction, speed as well as price quote time to your area; 2) secure all hatches; close all ports and windows. (Keep the water on the exterior.); 3) pump bilges completely dry and repeat as required. This aids remove “complimentary water influence.” (Sloshing of water in the bilge as the boat rolls which could impact stability.).

Your Marine Products Specialist Shares How to Dock Your Boat

Raritan Engineering Company your marine products specialists would like to share with you these topics we thought would be of interest to you this month regarding boat docking tips.

Your marine products experts know that we can’t cover everything about boat docking in one sitting, but I think you’ll be surprised at how many of the basic principles of close quarters maneuvering are embodied in the example docking which I will be discussing shortly.

That brings up another important point. Learning to marine dock is done on the water, in our boats, not by reading about it here. Book learning and good teaching are important, (I would say crucial), and allow us to focus our minds more quickly and clearly than just by using the trial and error method.

Port-side-to — a docking dissected

For the present purposes, I’m going to assume calm marine conditions, and not factor in the effects of wind. Wind is probably the hardest thing to contend with, when docking a boat.

What’s your angle?

Your marine ice makers experts know that the first thing to notice is that this boater is coming in at an angle. This makes it much easier to aim for a particular spot, and to bring the boat in close to the dock without scraping.

Coasting and the power turn

Secondly, think about what throttle setting you would use at the beginning of the approach. However, coasting is when “steerage”, the ability to steer, is at its minimum, because either i) there is no discharge current from the propeller to amplify the effect of the rudder, or ii) with inboard/outboards, most of the steering “authority” simply vanishes when the transmission is in neutral.

Keep up the momentum

The next thing the boater will do, as the dock draws nearer, is to start to turn the boat. However, this is also about the time that he or she wants to decelerate to a stop, in reverse gear. While slowing down, the vessel may be hard to steer.

Fortunately, boats in motion have momentum: once in motion, they tend to continue in motion, and once turning, they tend to continue to turn. This sometimes confounds the less skilled skipper, and yet momentum is exactly what to use when all other steering options fail, even for products purchasing experts. At just what point to turn, and how hard and for how long, I cannot say.

A walk in the dock

One final thing: it is very common for propellers to thrust asymmetrically, more on one side than the other, and in some boats the effect is often especially strong in reverse gear. The proper marine products are also needed to enjoy your traveling.

It’s because of this effect that we are discussing specifically port-side-to docking. Right hand propellers walk the stern to port, in reverse (a minority of propellers are “left hand” – for them, this whole discussion is a mirror image).


There is no conclusion to boat docking or in buying the right products. I have yet to hear the final word, and I’ve probably discussed and studied it more than most. Even if this port-side-to docking were all there was to know (and it’s not, it’s just the barest beginning), one could still spend a lifetime honing and refining the skills and techniques it requires.

So don’t forget these helpful points on learning how to dock your boat. 1) Know your angle;  2) know how to handle coasting and the power turn;  3) keep up the momentum;  and 4) the walk in the dock.

How Does a Marine Toilet Work?New Fresh Head


The first manual marine toilet to utilize pressurized fresh water – eliminates calcium deposits in discharge hose

  • Footprint is a direct replacement for competitive models
  • No Thru Hulls necessary when installed with a holding tank
  • Low water use toilet
  • Available as Left hand side pump
  • PHII toilets can be retrofitted by purchasing the retro-fit pump

With a diaphragm type pump and telescopic handle, flushing is extremely easy. Owners choose how much water to use. A lever allows water into the bowl to pre-wet it for a better flush. A built-in freshwater backflow prevention includes a vacuum break. A lock-out feature stops backflow coming in through the discharge when not in use.

Comparison of Macerating Toilets vs. Vacuum Marine Toilets

Macerating Toilets vs. Vacuum Marine Toiltes

There are several beliefs in marine products market about vacuum and Macerating Toilets. Some of these beliefs are true and some are myth.

Let us look at the how both technique satisfy basic toilet engineering functions:

Evacuation of all solids and liquid in one flush:

Vacuum toilet: Stored vacuum is applied to the bowl by opening a valve by paddle or electric. Pressure differential between atmosphere and vacuum pushes water and solids towards the cavity behind the valve. Bowl evacuates quickly in 2 to 3 seconds. As soon as air enters the bowl throat, vacuum drops rapidly. This evacuation technique make a loud noise associated with sudden pressure changes and reduced pipe sizes.

When user closes the valve, suction of the diaphragm vacuum pump is applied to the content of the cavity below valve. Solids and water and air start to move towards pump thru long hose between bowl and pump.

Pressure differential between atmosphere and vacuum accelerate water and solids during initial application of vacuum. Water and air move more rapidly than solids. In order to further accelerate water and solids pipe size is reduced after valve cavity. This sudden change in volume causes more velocity for water and solids and some breakdown of solid from bigger chunk to smaller chunk. After the valve is closed, suction of the vacuum pump moves air and water towards the pump faster than solids. Hence due to lack of positive pressure and water, there is a tendency for solids to splatter on the walls of hose and stay there till next flush.

Once suction of the pump had displaced all the air from hose and valve cavity to builds a preset vacuum level, pumps shuts off. This means pumps continue to run for 45 to 60 seconds after toilet use with typical diaphragm noise. If there is any slight leak in the hose connection or debris caught between valve seat and bowl throat, pump will turn on itself as vacuum drops. This may be an annoying if it happens in the night time.

Due to vacuum, spattered sewage on the hose wall is decomposing under anaerobic environment. Anaerobic odors include a wide range of compounds, most notoriously the reduced sulfur compounds (e.g. hydrogen sulfide, dimethyl sulfide, dimethyl disulfide, and methanethiol), volatile fatty acids, aromatic compounds and amines. Since system is under vacuum, it is unlikely that these odor producing gases escape thru hose. However these odors may be a problem at discharge side of the vacuum pump or during the flush cycle when vacuum level drops to almost zero. Due to notorious sulfur odors, some manufacturers only recommend special odor resistance hose for their vacuum system, increasing cost.

Macerating Toilet: Suction of the pump begins evacuation of bowl. Since pump is normally flooded with water at the beginning of the cycle, suction is powerful and draws solids and water from bowl cavity similar to vacuum toilet without loud popping noise. Most of the Macerating Toilets on the market are centrifugal pumps hence runs much quite than rubber impeller type. There is some gurgling noise similar to house toilets at the end of evacuation.

Suction of the pump is continuous and does not drops as stored vacuum does. Solids are macerated into very fine particles and send thru discharge at much higher velocity than vacuum toilet. Also since particles are smaller and have water as carrier, sewage move further into hose as compared to vacuum

End of the cycle pump stops, noise stops. There is no mysterious running of pump due to leaks or lake of vacuum. Power draw is measure by amps multiply by time. The macerator pump may draw more amps but draws less power compared to vacuum pumps.

Small macerated waste in the hose decomposes in aerobic environment. Aerobic byproducts of gases are odorless co2 and water. This means that a good quality rubber hose is all needed for system, no special odor resistance expensive hose is required.

The macerator pump eliminates waste clog in the hose or holding tank system as well as rinsing of bowl surfaces to remove all stains.
