A large percentage of sailboat owners only sail in light to no wind, they like the idea of a sailboat but not the motion offshore. Most powerboaters do not leave protected waters.
Many sailboat builders recognize this and build modern sailboats with a large cabin and cockpit, shallow draft and the rig is an afterthought, therefor most modern sailboats do well in protected waters without their rig.
However, sailboats made to sail rather than made as condominiums do not do well because the GM (metacentric height) is designed with the weight of the rig in mind. Without their rig the roll is quick, snappy and uncomfortable.
The metacentric height (GM) is a measurement of the initial static stability of a floating body. It is calculated as the distance between the centre of gravity of a ship and its metacentre. A larger metacentric height implies greater initial stability against overturning. The metacentric height also influences the natural period of rolling of a hull, with very large metacentric heights being associated with shorter periods of roll which are uncomfortable for passengers. Hence, a sufficiently, but not excessively, high metacentric height is considered ideal for passenger ships.
