HydroTab Interceptors 600SR Combo Moby Auto/NMEA

HydroTab 600SR Combo (2x300SR) Interceptor Set – Moby Auto (AUII NMEA 24VDC) Lightweight yet Powerful HydroTab’s latest SR Interceptor series offers all the advantages of HydroTab’s revolutionary vessel stabilization technology while maintaining a lightweight and compact design — without placing a heavy burden on your budget.

Lightweight yet Durable Design

The new striking look of the SR Interceptors is achieved through a composite body construction. This makes the interceptor lightweight yet extremely durable, capable of withstanding the forces generated at high speeds in open-water conditions.

Revolutionary Pneumatic Technology

The SR series is powered by HydroTab’s patented revolutionary technology. The interceptor movement is controlled by a high-resistance air bladder that expands pneumatically.

This simple concept allows for a mechanism that is fully open to seawater without the need for sealing or the use of components sensitive to marine environments (gears, shafts, electrical parts, motors, etc.).

In addition, this innovative pneumatic mechanism enables the application of high kinetic forces to the blades. These forces ensure that the interceptors continue to operate and remain unclogged even in extreme conditions such as barnacle growth and seaweed accumulation.

As a result, this simple yet innovative pneumatic system makes HydroTab interceptors virtually indestructible while allowing quick and easy installation.

Enhanced Boating Experience

Interceptors provide a much faster response time compared to traditional trim tabs. The resulting stabilization is superior, making boating significantly safer and more comfortable.

Too Simple to Fail

Structural strength combined with reliable pneumatic technology ensures long service life and flawless operation even in the harshest marine environments.

Eco-Friendly Design

Interceptors are made from recyclable materials, reducing production waste and carbon footprint.

The pneumatic system operates using compressed air instead of oil, eliminating the risk of marine pollution.

The SR series offers two interceptor models — 300SR and 450SR — allowing flexible configuration to suit different vessel sizes and requirements.

Custom Control Options

SR interceptors can be paired with one of three controller options:

• Moby Automation Controller

• 3DHC Manual Controller

• Trim Rocker Switches

HydroTab Innovative Trim Technology

HydroTab trim systems are based on the interceptor principle. A pneumatically movable interceptor is installed vertically on the transom, perpendicular to the direction of travel. This creates a pressure effect beneath the hull, lifting the stern upward.

This mechanically simple system is extremely compact and occupies only a fraction of the space required by traditional trim tabs. The simple and highly reliable pneumatic operation ensures long-term durability.

Differences Between Traditional Trim Tabs and Interceptors

Traditional Trim Tabs:

• Smaller and eccentric lift effect

• Limited adjustment capability

• Performance loss due to blade flexing

• Increased drag caused by horizontal lift component

Interceptor Principle & Advantages:

• Entire blade area contributes to lift

• No performance loss due to geometry

• Vertical lift effect close to hull

• Minimal drag due to small blade protrusion (few millimeters)

• Precise vessel control

The uniform pressure created by HydroTab interceptors through the expanding air chamber is evenly distributed along the blade, making them exceptionally durable in demanding offshore conditions (barnacle growth, floating object impacts, etc.).

Traditional trim tabs rely on hydraulic or electric actuators, which are prone to failure in harsh marine environments and are often too slow and weak for efficient stabilization.
