Brown Brothers' name has been synonomous with active fin stabilisers since the early 1930's.

Some of the benefits common to Brown Brothers' stabilisers include:

         Improved weapon performance

         Imprved sea keeping for helicopter operations

         Reduced fatigue

         Reduced equipment wear


Operations in severe sea conditions are controlled

         Added crew comfort



The "VM Series", the revolutionary folding fin stabiliser was launched in 1992. The two stabilisers in this range have recently been renamed as the Aquarius and the Neptune. The Aquarius offers fin areas from 1.8m2 to 3.5m2. Since the Neptune's product launch, 65 sets have either been delivered or are on order awaiting delivery.

The main features of these stabilisers are as follows:

         Consist of a retractable fin system, with an optimized high lift fin design.

         Modularized in a compact package for minimal installation costs.

         The design incorporates a high aspect ratio fin with no flap, thus cutting out underwater immersed bushes, pins, levers and linkages requiring maintenance.

         Fin tilting is accomplished with a linear actuator connected to the fin shaft through a Rapson Slide mechanism.

         Minimum moving parts maximising availability, reliability and maintainability. THerefore, recommendation for the holding of only a small quantity of "onboard" spares.

         Comparable performance to flapped fins.

         Minimum space envelope with small hull aperture.

         Prove digital "BITBUS" network control.

         Low hydraulics, minimising power.

         Minimum overall weight and loss of buoyancy.

         Modern digital control system incorporating fault monitoring and self-diagnostics, enabling automatic display of faults within the system.

         The fins can be up to 21.5 sq.m., the largest ever manufactured
