Repair, Tools & Materials

Its getting to be that time of year, when many skippers haul out or head south. Fall also heralds the beginning of boat show season. Here are some PS articles from the online archives that are suited for the season.

Were guessing 90 percent of sailors have their boat hauled by a yard. A travel lift or crane plucks the boat from the water, and yard guys block the boat for the winter. Your sole involvement is reading a warning in the lease agreement that you will not touch the stands and that you will not attach anything to them, including tarps. Those are good rules, and nothing we are about to say is meant to contradict them.

Regarding your recent Inside Practical Sailor blog post Drysuits vs. Survival Suits, I raft the Colorado river in Grand Canyon where water temps are around 50 F, even in the summer. The whitewater down there is furious and sometimes dangerous. I wear a 3 millimeter neoprene wetsuit under a full drysuit. If the drysuit rips, the wetsuit should slow down thermal loss. The problem is heat buildup in the sun. The solution is to jump in the cold water now and then to keep from over heating. On a sailboat that would be harder to do. There have been a few times sailing solo when I wore both garments, but it was pretty clammy inside. There is no perfect solution, just reasonable compromises by which to stay alive. Something to remember is that once a drysuit rips, it will take on hundreds of pounds of water. A high flotation PFD is mandatory, at least 26 pounds I would think.

The irregular shape of welds makes them difficult to inspect using ultrasound technology. Visual inspections can also be deceiving-especially with new welds. The prettiest bead can have internal voids and poor fusion. After a while, that pretty bead will begin to bloom with corrosion and cracks.

While many potential failures are easy to spot, some flaws are hidden under paint or within the structure, or are so small that a routine visual inspection wont pick them up. Standing rigging, hulls, decks and hardware fittings are the most common places where hidden structural weaknesses can lead to big repair bills, or even loss of life.

With more time than money on our hands, the sailors innate resourcefulness kicks in. Here are a just some of the penny-pinching projects tech editor Drew Frye has undertaken to improve his sailing life.

A key principle, at least from my perspective as an engineer, is knowing your boat. In 30 years of boat ownership, Ive only used contractor services for major sail work, new canvas (only because Ive never taken the time to learn), and hauling out. As a result, I know my boat inside out; thats a good feeling, an important part of seamanship, a blessing when something goes bust on a cruise, and a big help when time is available but funds are thin.

Our testers estimated that the exposure test was the equivalent of five years of exposure aboard a boat. Although the test demonstrated that a DIY solution using sandwich bags can nearly match performance, it also demonstrated that the makers claims of five years of protection could, in practice, be accurate.

We wished they could be as maintenance free as the carbon canister on your car, but they lack the regeneration cycles programmed into your car. The makers say the silica gel resin should be replaced annually, but Practical Sailor testers have found that three years is about right for diesel and five years for E-10 gasoline.

Cleaner than coil and grease coatings, these bags protect areas that are hard to reach. Additionally, the protective coating does not need to be removed, since it is very thin and will slowly evaporate once the part is removed from the bag.
