Repair, Tools & Materials

You can’t maintain a boat without ordering a few marine supplies, so Practical Sailor readers offered (mostly) high praise and appreciation for our guide...

Online juggernaut Amazon, big-box behemoth Walmart, and West Marine—with more than 250 stores nationwide—are the biggest sellers of marine supplies in North America. But...

Are the tapered plug seacocks on your boat difficult or impossible to close? If you tighten the adjustment nut enough for them to stop weeping all over the inside of your boat, does it take two hands and a hammer to operate them? If so, it's time for an overhaul. Even if they worked well last season, a little care while the boat is hauled can save you a lot of grief in the future. As part of your boat's routine maintenance, tapered plug seacocks should be disassembled, cleaned, lubri­cated, and reassembled on a regular basis.

Simple ferrous-metal oxidation is a process in which iron, oxygen, and water chemically react, and it can cause rust to seemingly weld fasteners together. This unyielding grip often turns disassembly into much more of an ordeal, but with a few, regularly available products and a good set of wrenches, the big battle becomes a minor squabble.

Owning and using a boat is all about maintenance. While maintenance is not fun—it can be filthy and arduous—it must be done if you...

In the old Star Trek TV series Captain Kirk would press a button on a machine called a replicator and request banana cream pie,...

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

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.

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.
