To estimate displacement, we calculate the volume of water displaced by the submerged portion of the spar. The spar is designed to have a chord of 10 feet, a thickness of 5 feet, and a length of 39 feet. The bottom 70% of the spar is underwater, so the submerged length is approximately 27.3 feet.
Volume of displacement = Chord × Thickness × Submerged Length = 10 × 5 × 27.3 = 1,365 cubic feet. >.
