Question

buoyancy

Answer 1

the upward force of water displaced by the hull

Answer 2

when a boat is at rest, the center of buoyancy acting upwards(vertically) is below the center of gravity acting downward. at this point the boat is considered to be in equilibrium.

Answer 3

frames-attached to keel which extend athwartship(from one side to the other) the skin of the boat is attached to the frames. the keel and the frames strengthen the hull to resist external forces and distribute the weight. stem-an extension of the forward end of the keel. there are a common number or shapes, all are normally slanted forward(raked) at an upward angle to reduce water friction. sternpost- a vertical extention of the aft end of the keel

Answer 4

the weight of a boat , and is measured in long tons(2,240lbs) the entire cubic capacity of a boat expressed in tons of a 100 cubic feet the carrying capacity of a boat expressed in tons of 100 cubic feet. it is calculated by measuring the cubic content of the cargo and passenger spaces. the difference between the light displacement and the max loaded displacement of a boat, and is expressed in long tons or lbs.
