DIY Tiller Lock and Emergency Tiller Pilot

Whether you own a Raymarine Tiller Pilot (ST1000 or ST2000) or the Simrad Tillerpilot (TP10, TP22 or TP32), the day may come when this...

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.
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.
The bare minimum required to deal with most daysailer dilemmas fits in a relatively compact electrician’s bag. It can be tailored to fit the specific needs of your boat. (Photo/ Drew Frye)

The Get-Home Sailboat Tool Kit

The tools and materials required to maintain and repair everything on a boat will barely fit in a room. Just the kit required to maintain vital systems will raise the waterline of a large boat and is impractical in a smaller boat. Fortunately, when day sailing and even cruising locally, all we really need to do is get back to the dock...any dock.
Hot Knife. We put this purchase off for too long. Nice for fabric and rope, and vital for carpet and bungee cord, which are difficult to heat seal. Multiple layers dont slow it down. (Photo/ Drew Frye)

Although the OTC Hose Removal Tool is meant for the automotive industry, we found to be the most useful option for marine sanitation hoses.

Hose Fitting Tips

Pulling hoses is generally low on the fun list. They are in bad places, jammed onto crusty hose-fitting barbs, and have stiffened over the years. As part of our 2016 update on long-term tests, we needed to wiggle loose a few of the sanitation hoses were testing to see how they were looking on the inside-a job much less pleasant than new installation.
The captain made a navigational miscalculation so this 2005 Sabre 386 rested on a shelf just outside Cameleon Harbour in British Columbia for the tide to return. As a result of this temporary grounding, seagrass entered and blocked a through-hull. Identifying details have been omitted at the request of the captain. (Photo/ Bert Vermeer)

DIY Fairing and Filling

Epoxy deserves its wonder resin status as a highly adhesive, water-resistant laminating resin. It is the secret sauce behind a shelf full of fillers, glues, and fairing compounds.
