Abstract
The invention relates to a fin stabilization system adapted to minimize roll about the longitudinal axis of the boat during sharp cornering at very high speeds. In one form, equipment such as a machine gun is mounted to the bow of the boat and targets are adapted to be engaged in high-speed maneuvers when cornering and the deck of the boat is not excessively rolled whereby blocking visibility in a turn.
Claims46
A fin stabilization system adapted to be mounted to the area of influence of a boat which consists of the longitudinal rearward laterally outward one-third section of the boat having a longitudinal, lateral and vertical axis, the fin stabilization system comprising:
- a) a first fin and a second fin positioned in the area of influence of a boat having a rearward effective portion and a forward effect of portion and a depth whereby the first and second fins are parameterized where each are positioned to according to the following ranges:
- i. a rear base distance from the longitudinally rearward portion of the boat to the rearward effective portion between the ranges of 5 in.–12 in.,
- ii. having the distance between the rearward effective portion and the forward effective portion of no more than 70 in.,
- iii. having a depth component that is less than 6 in.,
- b) whereby the fin stabilization system is adapted to maintain the roll of the boat about the longitudinal axis of no more than 20° from a horizontal plane in a turn in excess of speeds of 35 mph of the boat and the first and second fins are attached to a first and second mounting brackets each having a base region and a mounting extension whereby the base region is rigidly mounted to the lateral portion of the hull and the first and second fins are mounted to the mounting extensions of the first and second mounting brackets respectively.
