The revolutionary trim system


The revolutionary trim system


by BSondag
Hydrotab is an innovative patented trim system designed for maximized efficiency and optimization of boat control and characterized by absolute simplicity and robustness. Their trim tab interceptors are designed to operate in the harsh sea environment, and improve your boat cruising experience.

The Operating Principle

Interceptors is the future in boat trimming as they continuously build trust among boat builders, but there is a fundamental difference that make our interceptors unique.

The motion of the interceptor is achieved through a high resistance bladder which is expanded pneumatically. This simple idea allows us to have a very simple and open to the sea water mechanism without any sealing that in the same time creates very high shifting forces (up to 2000 kg).

Key Benefits

This is what makes Hydrotab interceptors different.

  • Instant lift effect
  • Increased safety in bad weather
  • Enhanced fuel economy
  • Improved boat control


The Hydrotab interceptors are characterized by extreme robustness and total simplicity in construction. The system is open without any sealing part. The housing is constructed by high quality Inox 316 stainless steel, while the blade is made by lightweight composite material which is resistant to sea fouling.


The principal of simplicity is obvious in every aspect of the product. We are proud of of having succeeded in our goal of constructing the most robust product with the simplest installation in the market.
