YACHT AND CATAMARAN STEERING Steering CATAMARANS • SAILBOATS Yacht steering WITH feedback Many traditional sailors have resisted changing to hydraulic steering due to a loss of feel or feedback common with many of the hydraulic systems on the market. With the introduction of the new Admiral HD Series helm units, HyDrive introduce an Evolution in Yacht Steering. As a result of years of intense research and development, HyDrive Hydraulic steering offers huge advantages for sailing boats :Simple installation with hydraulic tubing that can be run literally anywhere on the boat - no more...

FEED BACK OPTIONS FOR SAILBOATS Feedback ELECTRIC BY-PASS With Dual Stations or Single Stations fitted with HYDRAULIC autopilots, the helms (pumps) require isolation from each other to prevent motoring each other under pressure and failing to steer the boat accurately. The FEEDBACK-DS12V (for 12vDC or FEEDBACKDS24V for 24Vdc) unit incorporates a dual lock valve for isolation of the two stations. This lock valve is automatic and does not prevent normal operation of the steering. Simply turning the wheel operates the valve and the steering functions normally. When you stop rotating the wheel...

WHICH UNIT WILL FIT MY BOAT? Which one? GENERAL INFORMATION Dual Stations For outboard steering selection, the most important requirement is the amount of room available either side of the outboard motor. Unless you have a pair of very large horsepower motors, any of the kits, from the Sportkit to the powerful OBKIT1 using the 210BH cylinder, can steer your boat. The ultimate decision comes down to a combination of personal preference, your budget, and the amount of enginewell space available. The drawings on the rear page provide you with the minimum space required for each type of...

BYPASS - NC12V BYPASS - NC24V For use with Catamarans REMOTE BY-PASS VALVES FOR FLUID-LINK CATAMARANS For larger vessels where manual activation of the manual by-pass valves (CatN8, 330C etc) are difficult, a remotely activated 12 or 24VDC bypass valve can be fitted. This allows alignment by the simple flick of a switch, and is adjusted by using the steering wheel and rudder angle indicators. Valves come with blank female ports, and fittings are an additional cost. Valves need to be correctly selected to fit the tubing used in the installation. BYPASS - NO12V BYPASS - NO24V For use with Linear...
