What this video covers
Sailboats remain upright primarily due to a heavy lead keel that acts as a counterweight to the mast and sails.▶ 1:11 On a typical vessel like a Beneteau 423, this keel can weigh over 6,000 pounds, providing enough ballast to prevent capsizing.▶ 1:33 As a boat heels, the sails naturally spill wind, which reduces the force acting on the rig and serves as a pressure release valve.▶ 2:16 Sailors can evaluate a boat’s stability by checking its capsize screening formula on sites like SailboatData; a value below 2.00 indicates high stability suitable for ocean passages, while values above 2.20 suggest a more tender vessel.▶ 2:30 Sailboats are inherently slower than powerboats because their heavy keels prevent them from planing on the water's surface.▶ 4:18 While sinking is rare, it typically results from hull breaches at instrument transducers or through-hull fittings.▶ 4:40 Sailors should maintain wooden bungs near all underwater inlets to plug potential leaks.▶ 5:29
