Hydrotab Interceptors


Find out what makes Hydrotab Interceptors far superior to conventional Trim Tabs!


Conventional Trim Tabs’ lift effect is applied in an angle relative to the hull, resulting in loss of lifting force and substancial drag. The sharp deployment angle of Interceptors ensures a greater lift force, vertical to the hull!

Trim Tabs:


Trim tabs after long periods at sea create extra drag due to the fouling accumulated on their working surface.

Interceptor continue to operate with fouling build up - the blade is unaffected!

Hydrotab further innovates by introducing the SR Interceptors – The composite body, robust Interceptors that prevent fouling build-up completely!


The sturdy and compact body combined with the even distribution of force along the blade makes the interceptors virtually indestructible. Moreover, even in situations of extreme fouling build up, the blade continues to operate normally and reliably.

Trim Tab geometry allows the uneven distribution of force, making them prone to warping and damage.

The interceptor deployment force is evenly distributed, making the blade withstand the high forces of the open sea

Traditional trim tabs rely on hydraulic or electric devices to extend, which can often easily fail under harsh conditions (fouling) or not provide enough force to move the blade (electric acuators). Hydrotab’s interceptors have few moving parts and no hydraulic/electric devices and due to their patented pneumatic technology they are able to produce high shifting forces with very low (2,5 bar) operating pressure.

When backing up, Trim Tabs make it hard to control the boat, and are vaulnerable to breaking.

In harsh conditions, trim tabs can be stressed to the point of the mechanism being completely destroyed.

Overall Technical Comparison

Trim Tabs:



Hydraulic Trim Tabs leak harmfull hydraulic oils into the sea, in case of cylinder seal failure due to fouling.

Since the interceptors operate using compressed air, they do not pollute the marine environment with harmfull chemicals.


¬†Hydrotab’s Interceptors offer a stylish solution to boat stabilizing. Trim tabs are bulky and¬† protrude from the hull, while Interceptors sport a very eye catching look, and their compact design makes them seamlessly blend in any hull!
