Abstract
The invention involves a double trim tab for watercraft in which connection the flow interceptor (1) is activated by an actuation cylinder (4) and the flow interceptor (1) activates the bottom tab (2). One of the tabs may have a course correction device (10) or a course correction fin (11). In addition, an electronic steering device (14) can likewise carry out a course correction in the event of a trim change in which connection the steering wheel (17) is kept neutral by means of an uncoupling device (18).
Claims16
A double trim tab (A) for watercraft, comprising:
- a bottom tab (2), said bottom tab configured for mounting to a watercraft;
- a flow interceptor (1) pivotally mounted at an upper side of the bottom tab to pivot toward and away from the bottom tab about a first laterally-extending axis, said flow interceptor including a flow interceptor end (1a) extending toward the bottom tab to overlap one of a forward edge and a rear edge of the bottom tab extending generally laterally between outer longitudinal sides of the bottom tab;
- and
- an actuator (4) connected to the flow interceptor and configured for mounting to the watercraft for upwardly and downwardly pivoting the flow interceptor between a raised position with the flow interceptor end above a bottom surface of the bottom tab, and a lowered position with the flow interceptor end extending below the bottom surface of the bottom tab.
