Sec. 25.755 - Hulls.
(a) Each hull must have enough
watertight compartments so that, with any two adjacent compartments
flooded, the buoyancy of the hull and auxiliary floats (and wheel tires,
if used) provides a margin of positive stability great enough to minimize
the probability of capsizing in rough, fresh water.
(b) Bulkheads with watertight doors may
be used for communication between compartments.
