INVESTIGATION OF BOAT MOTION ON OCCUPANT IN PATROL BOATS

Occupants in high-speed patrol boats are subject to impact forces due to various boat motions. These impact forces should be precisely calculated and accounted for when designing seats for occupants. Hull design and cruising speed are the most critical parameters that cause shock and impact on the b...
