A sailboat or sailing boat is a boat propelled partly or entirely by sails smaller than a sailing ship. distinctions in what constitutes a sailing boat and ship vary by region and maritime culture. distinctions in what constitutes a sailing boat and ship vary by region and maritime culture.. Charles doane. charlie is cruising editor for sail and has been associated with the magazine since the mid-1990s. he has more than 45,000 bluewater miles under his keel, including six transatlantics and three singlehanded passages, and has owned and maintained three different cruising boats over the years.. Ballast is used in sailboats to provide moment to resist the lateral forces on the sail. insufficiently ballasted boats tend to tip or heel excessively in high winds. insufficiently ballasted boats tend to tip or heel excessively in high winds..
How sailboats measure up. design ratios tell a story, but to get the real picture about a vessel, sail area, displacement, and ballast deserve a longer look. cruising-boat design drifted away from raceboat design, and sail plans began to change. b/d doesn’t take into account the location of the ballast. take a boat that has a total. Beam, ballast & displacement as they relate to seakeeping . this is very much counter to the often assumed requirement for a specific 'ballast ratio' on sail boats, or that there must be a certain amount of ballast present for the safety of a power boat. for any new design, after a thorough weight analysis is done in order to determine. However, with the help of design ratios, you can not only compare and contrast different designs, but get a pretty good idea, sight unseen, as to how a boat is going to perform under sail. the beneteau sense 46 is a typical modern cruising boat, with an sa/d of 19, a ballast ratio of 28 percent and a d/l of 159..
