What type of hull does the 45' have? - Semi-displacement
What type of hull does the 29' have? - Planing
2 keel types: - bar keel or flat plate
, displacement - weight of boat measured in long tons or pounds
stability - the tendency of a vessel to remain upright
2 primary forces that affect stability: - gravity and buoyancy
center of gravity - the point at which the weight of the boat acts vertically downwards
equilibrium - when the center of buoyancy is directly below the center of gravity
heeling - temporary leaning of a vessel
listing - permanent leaning of a vessel
rolling - side-to-side motion of a vessel
2 types of stability: - longitudinal (fore and aft) and transverse (athwartships)
moment - the force that causes a vessel to return to an even keel
righting moment - force causing a vessel to react against a roll and return to an even keel.
effects of freezing spray: - freezing spray can cause ice to build up on the deck, adding weight that can
influence the center of gravity; can also complicate the use of boat equipment
45' max personnel - 24 (210 lbs each)
45' max seas - 12 ft
