Stability. Centre of gravity –boats weight pushing towards water Centre of buoyancy – upward force –size and shape of hull. Stability. If CG rolls over CB then boat will roll over This is the AVS. Stability. Keep weight low CG is lowered Water ingress creates movable cargo – CG moves.

Stability • Centre of gravity –boats weight pushing towards water • Centre of buoyancy – upward force –size and shape of hull
Stability • If CG rolls over CB then boat will roll over • This is the AVS
Stability • Keep weight low • CG is lowered • Water ingress creates movable cargo – CG moves
Stability • Sailboat more stable –keel • Keep weight off rigging • Keep water out!
Stability • RM zero • RM max @ 60 • RM decreases as boat heels • AVS RM is zero –boat can right or roll over • Negative RM • RM zero
Stability • Breaking waves!!! • See P50 + 51 Yachtmaster Course Notes Book
