A superstructure-integrated backspray mitigation system for yachts including an aft spoiler secured to the vessels hardtop for directing airflow about the hardtop downwardly into the aft cockpit area to interfere with, mitigate and eliminate the natural reverse backspray created by the low-pressure region behind the yacht. The spoiler protrudes from the hardtop and includes at least one air ducting channel directing airflow at select angles into the cockpit area presenting a protective shield preventing the backspray from entering the cockpit. An optional pivotal panel member selectively enables operation of the spoiler.

Backspray mitigation system for yachts

A Vee bottom planing boat hull (32) has right and left steps (44 and 46) positioned so as to optimize the boat's trim angle at top speed, and defining right and left notches (48 and 50) in which are pivotally mounted left and right trim tabs (56 and 58) having forward leading edges (60 and 62) along oblique pivot axes (64 and 66) causing outer corners (102 and 104) of trailing edges (68 and 70) of the trim tabs to move downwardly more than inner corners (106 and 108) during downward pivoting of the trim tabs, providing an active hull to control boat trim angle and effectively reduce deadrise angle while maintaining a running surface trailing edge substantially free of discontinuities in the vertical direction.
