Your Thru Hull Fittings Suppliers Share Tips to Consider Before Buying Your Next Batch of Anti-Freeze

Raritan Engineering your thru hull fittings professionals would like to share with you this week some great information regarding which anti-freeze could be best for you and your boat.

There’s nothing like buying several $3 bottles of antifreeze to protect your $30,000 boat, then coming home to discover the unused bottles frozen solid in your garage.

The onset of winter always brings queries about the effectiveness of certain anti-freeze concoctions. A couple years back we got a letter from Mark Baldwin, owner of a Seasprite 34, Ella, in Blue Hill, Maine.

It just so happened that when Mark’s query arrived, we were in the middle of testing various antifreeze formulas for their effectiveness. 

Uni-Gard pink is listed as having 25- to 35-percent propylene glycol, which should provide the -50-degree burst protection claimed on the bottle. 

If, however, there is a lot of water still left in the boat’s plumbing lines, the protection against freezing is diminished, and the anti-freeze can become even less effective through each freeze-and-thaw cycle. Ideally, during the winterizing process, the anti-freeze is flushed through the system to remove standing water from any low spots.

We Discuss How to Identify the Wrong Anti-Freeze For Your Boat

Your thru hull fittings specialists talk about how propylene glycol can harm components in freshwater and wastewater plumbing systems as well, but because ethylene glycol is not a safe choice for potable systems, there are no other antifreeze choices, other than draining the system.

Some sailors have suggested using Vodka as an antifreeze for potable water systems, but this turns out to be an expensive myth, and our tests have thoroughly debunked it. Not only will it burn holes in your pocket, it will turn your tanks and hoses into a fecund biome.

However, the EPA also cited several ways in which glycol can indirectly harm aquatic life by raising oxygen levels, etc. In our view, both formulas need to be used with care on land and near the water, and disposed of properly. Ideally, all glycols should be flushed and purged so that they can be captured for recycling.

Our research into the various anti-freeze additives on the market has produced many interesting findings, among them the correlation between improper winterizing and a stinky water tank.

Finally, here are a few other important tips.

  • Never use ethylene glycol, which is highly toxic to humans, in potable water systems. The best practice is to drain the water tanks and lines of all water. When this is not possible, drain the tank and circulate propylene glycol only through the plumbing to ensure all low spots have been purged of water, then leave propylene glycol in plumbing through the winter. 
  • Never use winterizing propylene glycol in the cooling system of a glycol-cooled engine. Diesel engine coolants are specially designed to prevent corrosion in the cooling system. 
  • Some antifreeze formulas aimed at the RV market have ethyl alcohol in them that can damage PVC plumbing hoses. Look for products with no ethyl alcohol.

So don’t forget these reminders about finding the right anti-freeze for your boat. 1) Using vodka as a substitute is a myth;  2) Never use winterizing propylene glycol in the cooling system of a glycol-cooled engine;  and 3) look for products with no ethyl alcohol.

Leave your boat sitting pretty this winter

Owning a boat can be a great source of pleasure, offering fun in the sun, relaxation and adventure, but it’s not something that comes without responsibilities. Maintenance and regular detailing is critical to prolonging the life of any boat or yacht and, by taking extra measures, you can help ensure that your enjoyment on the water is always maximized. 

Comfort inside, sun outside – While a boat brings fun and adventure, having the ability to take a break from the heat and cool off in the cabin is a true luxury. However, if the inside of your boat is just as warm as the deck, you’re likely to have to cut your day on the water short. 

Reduce glare, improve safety – Regardless of your boat’s setup, sun glare can be uncomfortable and dangerous – especially for your captain. By having a professional install window tinting, your boat’s windshield will block glare to lessen eye fatigue and improve visibility, even when the sun shines brightest, helping you always remain in control of your vessel. 

Block UV rays, prolong the fun – A day on the boat should be just that – an entire day – but without protection, hours spent in the sun can prove harmful. When on the water, having the option to take a brief break and cool off is pivotal and, with window tint, you get that option. 

Privacy and protection, even when away – Ensuring privacy and security of your vessel when docked or in storage is important to its longevity. With window tint, your boat and the valuables inside are kept private and the condition of the fixtures and furniture within the cabin stay protected from sun damage. 

Having your boat or yacht tinted is not just for style and comfort, it adds extra value to your vessel, too. While it’s a wise decision, marine window tint installation isn’t as cut-and-dry as one might think, and in order to get the ultimate benefits, it’s highly recommended to have a window tinting professional work on your boat.

Your Thru Hull Fittings Suppliers Discuss How to Prepare Your Marina Bound Boat for the Next Tropical Storm 

Raritan Engineering your thru hull fittings experts would like to share with you this week some great information regarding how to avoid the frustrations of damaging storms to your marine bound boat. 

With Hurricane Irma poised to rake Florida and other states with storm surge and 100-plus knot winds, the storm poses a serious threat to boats all along the East Coast. 

Practical Sailor has covered storm preparation on several occasions. The two most extensive articles appeared in July 2008 “Gear for Battening Down Ahead of Storms,” and “Tropical Storms Dos and Don’ts,” from November 2011. 

Our first choice in a storm is a haul out facility, preferable well-inland and out of the path of the storm.The facility shouldn’t be vulnerable to storm surge, and it should be equipped with fixed anchors to tie your boat down. Second choice would be a hurricane hole with good holding, again well inland and out of the storm’s path.  

• Dock line size varies both with boat size and expected wind speed. Boats docked in hurricane or other severe weather areas should consider going up a size from common recommendations. 

• Loads on the cleat of a 35- to 40-foot boat during an actual hurricane can exceed one ton. While boat building standards (the American Boat and Yacht Council in the U.S.) specify load-carrying ability, some older dock cleats are not up to snuff. 

• If your boat is 30-feet or longer and you do not yet have mid-ships cleats for attaching spring lines, consider adding them at the next opportunity. These should be sized and backed in the same manner as bow cleats, since loads are the same or greater. t is best aligned to withstand the loads (see above point).

•Remember the chafing gear. Preferably something water can permeate for cooling and lubrication. For a round-up of effective chafe gear see “Round 2: Chafe Gear for Mooring and Dock Lines,” October 2012.

• Removing canvas and sails reduces windage. Specifically, remove the furling jib, one of the most common storm casualties. Dodgers and other canvas will also suffer if left up during the storm.

Your Thru Hull Fittings Manufacturers Continue Talking About Protecting Your Valuable Boat During Stormy Times

• Use plenty of fenders. Your thru hull fittings professionals talk about how fenders need to protect you from the dock and neighboring boats. A fender board can be particularly useful in some scenarios. 

• Check your neighbors’ lines. If the boat appears to pose a threat to your own, try to contact the owner, and notify the marina staff. Failing these, deciding whether to take action yourself is a personal decision. What would you want someone to do if the boat was yours?

• Floating versus fixed docks. Properly designed floating docks are generally considered a safer option than fixed docks, with some important caveats. The support pilings must be high enough for the predicted storm surge. 

• Using anchors. If you side-tie and you don’t have a tie-off point opposite to your dock, well-set anchors with plenty of scope can help relieve the pressure on your fenders. Unfortunately, many marinas offer very poor holding. 

• Lastly, any marina facing significant storm surge is simply not safe, but those protected from a long fetch by a low wave barrier are particularly vulnerable. Boat owners on the Chesapeake got an expensive lesson in this during Hurricane Isabel. 

How To Protect Your Boat During A Hurricane

Land Storage

Boats stored on land tend to fare better than boats kept in the water. If you’re able to arrange haul-out and storage, choose a location on high ground, since low-lying areas are prone to flooding during a hurricane.

Millville, NJ business Raritan Engineering is proud to announce that it has been given an exclusive distributorship by Tru-Design for the new load design ‘thru-hull’ plastic load bearing fitting. These fittings fully comply with ABYC H27 specifications, allowing the use of below the water line thru-hull fittings when fitted with a Tru-Design collar and ball valve. Further details can be seen athttp://www.raritaneng.com/product/ball-valves/.

“We are very happy to announce our exclusive distributorship of the Tru-Design thru-hull fittings,” says Kim Shinn from Raritan Engineering. “We fully believe in the quality of this product, which is compliant with all relevant legislation and intend to serve our customers even better than before.”

The Thru-Hull Fittings by Tru-Design are constructed using the most up-to-date high-impact composite materials. This means that they will last as long as the vessel will. As such, vessel owners won’t need to worry about this issue. Each element is created using glass-reinforced composite materials. As such, they are highly durable while remaining lightweight. Furthermore, the materials are resistant to corrosion and electrolysis. This means their lifespan is dramatically increased without compromising performance. It also does not require any external bonding system.

The fittings are fully chemical resistant, meaning they can handle anti-fouling paints, oils and diesel. Furthermore, they are fully UV resistant so that they don’t discolor or lose their integrity when exposed to ultraviolet radiation. Kim Shinn adds, “What sets the Tru-Design Thru-Hulls apart from their bronze counterparts is that they have a high quality surface finish. As such, there are no discoloration issues as you would see with a green film. Plus, they can be painted using any kind of anti-fouling paint without the need to first grind and then clean the flaked paint. Rather, it can be applied straight away on anything within a marine environment of between -4 and 230 degrees F. These include all hull types such as aluminum, wood, steel or GRP.”

As can be seen on http://www.raritaneng.com/, Raritan now stocks the full range of Thru-Hull fittings. They come in sizes ranges from half an inch to two inches. Furthermore, customers can choose tail, recessed or threaded models. Each item is suitable for waste treatment, as shown on http://www.raritaneng.com/catagory-pages/waste-treatment/, as they comply fully with the necessary ABYC H27 specifications.
