A displacement hull can be driven faster than its hull speed, but only at enormous cost to fuel consumption and power requirements. A displacement hull typically has slack bilges, making it less stable initially as it rolls, but tremendously stable at extreme angles of heel. A hard chine-planing hull on the other hand may be very stable initially, but be less stable ultimately. The same characteristics that make a displacement hull more prone to rolling also make it more efficient to drive through the water, which makes transoceanic ranges possible. Trawlers are also built with semi-displacement hulls for added speed capability at the obvious expense of range.
Layouts vary, but a pilothouse configuration is common and well suited to extended at-sea living.
Sometimes called flybridge motoryachts or offshore cruisers, they offer both main deck and Fly-bridge helm stations. Bow rise is minimal on many of these models, thanks to careful weight distribution, making it possible to run a 65-footer from the lower helm with a clear view ahead, even when coming up on plane. Most of these yachts are very well finished.
