Boat Maintenance

Depending on the collection area and the sailing, salt can be a primary problem. Spray falls and dries, layer after layer, until the decks hold enough salt to foul a considerable flow of water. The solution? Wash the deck with seawater before the rain comes. Squeegee off as much as practical or towel dry, and common sense dictates this is best done when at sea and must be done away from red tides. We tested the run-off from the top after scrubbing with seawater, allowing to dry, and then spraying with tap water equivalent to 1/10-inch of rain (see results in table below). In addition to taste, seawater contains significant sulfate levels, which combined with bacteria in the tank under anaerobic conditions, can lead to sulfurous water; sailors notice this when a seawater flush is used for the head, but allowed to become stagnant for a few days; the first flush will smell.

When I searched the internet for advice on repairing a small leak between the lens and sealant on a 20-year-old Lewmar Ocean 60 hatch, on my 1996 Valiant 42, I was dismayed by the dearth of information. Even the Lewmar site does not provide a schematic of the hatch or a service manual. You can purchase a new gasket but that is not what is leaking. There is no mention of the sealant. Hatchmasters quoted a repair cost 1/2 the price of a new replacement with a greater than four-week turnaround. I would still have to remove and replace the hatch. I will wing it, but thinking that if it came to that, I would definitely not want to replace it with a hatch I could not readily service myself. In my subsequent search I found a reference to a PS July 1, 1994 comparison of Offshore Deck Hatches. I was then dismayed to find that the PS archives stop at year 2000. Fortunately, after some rummaging I found the print version. It was still relevant and useful. In fact as far as I can tell, it is the most recent hatch comparison out there.

Each winter sailors must tackle the project of winterizing their potable water system. Our preferred method is to dry the system completely (see PS September 2014, Step-by-Step Winterizing tips. If thats not possible we completely empty the tank and then treat the plumbing with the correct concentration of anti-freeze. The online version of this article provides all the details you need to carry out this process, as does the recent Inside Practical Sailor blog post, The (Cold) Case of the Frozen Anti-freeze.

Three and a half years ago I had a Hurricane hydronic heater installed on our 1969 Grand Banks 32, Athena. Compared to our prior Espar hydronic heater, I have been exceedingly pleased with the Hurricane. It has been completely reliable and it is very easy to service. Recently though, after the unit was out of warranty, the fuel pump failed after 300 hours of use. The Hurricane technician who replaced the failed fuel pump indicated that normally the fuel pumps last much longer, generally 3,000 to 5,000 hours.

If youre going to sail youll be doing some stitching. No two ways about it. Dont jump into the $100 do-everything kit. Start with a modest kit, adding tools and materials only as your skills grow and projects require them. You already have most of what you need in your other supply lockers or tool boxes. Study a good book on sail and canvas repair, concoct a few small projects for practice.

Regarding your recent blog post on the future of wood on boats (see Farewell to the Wood-trimmed Boat? Inside Practical Sailor blog), my last boat was a beautiful, cold-molded (West System) custom 26-footer designed by Gary Mull. It was built by the very talented late Jim McClelland of McClelland Boatworks in Kenora, Ontario.

Two different harbors suffered almost the same fate as Hurricane Irma raked South Florida with hurricane force winds. In both places, tens of thousands of dollars in damage might have been prevented had the owners of large vessels better secured their boats.

Our recent test of caulk removers, (PS Tests Caulk Removers, Practical Sailor, January 2017), focused primarily on silicone caulk remover because these caulks can leave a residue that makes it impossible for anything to bond. After that test, we got a call from reps at Debond who explained that their product, although effective with silicone, is formulated to break the bond between to break the bond between 3M 5200 and a smooth gel coat surface. This is a common challenge for sailors who must disassemble through-hulls, remove chainplates, or repair structural components. So we went back to the lab to find the best antidote to 5200, and we present the results of our tests here.

The cost of masthead tricolor navigation lights, a safety improvement many sailors add to their boats, involves expense beyond the fixture itself such as a switch on the DC panel, additional wire to snake from the panel to the masthead, through-deck fitting, and labor.

A respirator can't protect you if it doesn't fit your face. Its that simple. Anything that prevents a good seal-whether facial hair or a hollow under the side of your jaw-is unacceptable. In a workplace this fit test will be performed in a very rigid manner by a trained technician. However, for the sailor/occasional boat yard worker, we offer this shortcut procedure that is far better than nothing.
