Boat Maintenance

This Groco Bronze Thru-Hull Fitting is a good candidate for mortising, so it will be flush with the hull. Note, mortising is best suited for solid laminates or thick hulls. (Image source: Jamestown Distributors)

Fair Through Hull Fittings: Essential to a Smooth Bottom

In light air, a major portion of the total resistance of a sailboat derives from skin friction. To oversimplify, the smoother the boat's "skin" — the submerged part of the vessel — the less power is required to drive it to a given speed. Put another way, given two boats identical in every way, including sail area, the boat with the smoother bot­tom will be slightly faster than a boat with a rough bottom in light air. Most racing sailors have learned the value of a smooth bottom. Ironically, cruising sailors can benefit at least as much from the creation of a low-resistance bottom as racing sailors, although you rarely see a cruising or daysailing boat with a bottom to match that of a good racing boat.

No need to pay for a pricey teak cleaner, you can successfully use a DIY brew to clean your teak.

Spiffy Teak Tips for the Penny Pincher

Most teak cleaners don't just clean; they also remove weathered woods surface fibers and expose new wood. As much as 0.010 inches of surface teak can be removed in a single cleaning when using some common teak-cleaning products. Regularly cleaning with these products will shorten a teak decks life. Some also contain strong alkalis that can harm paint, caulk, and aluminum.
Canvas biminis and custom coverings are expensive, so it is worth your while to treat them with the most effective protective treatments.

Keeping Canvas in Tip-top Shape

Canvas dodgers and biminis are the hallmark of a cruising yacht, but they arent cheap to come by. We wanted to find the best way to protect the investment and get the most life out of the canvas. Sunbrella makers recommend that routine maintenance include frequent freshwater rinsing, plus spot cleaning, and applying a treatment to restore the fabrics repellency. In this article, we take a look at treatments designed to keep on-board canvas water repellent and looking its best. We tested seven: Aquatech, Marykate, 3M, 303 Products, NikWax, Star brite, and Iosso.
We placed standard samples of aluminum, steel and brass in a separate container of each solution to measure corrosion over time. The samples were weighed to the nearest milligram before testing began, and then at two hour intervals.

Descaling Solutions for Boats

In addition to all of that lovely salt, seawater is very hard, nearly saturated with calcium. All it needs is something to react with (uric acid in the head) or localized overheating (engine) to create concrete-like incrustations. Sometimes mechanical removal is possible; a favorite cruiser ritual involves hauling out the sanitation hoses and beating them on concrete to remove internal scale build-up. Heat exchangers can be reamed out with a rod, but most engine and plumbing systems are inaccessible without considerable disassembly.

Rethinking Sailboat Structure

When it comes to describing a sailboats most valuable attribute, its surprising how varied opinions can be. Staying afloat should be our first priority, and although you seldom read or hear much about it at boat shows, the structural elements that hold a sailboat together are an all-important consideration.
