    360° retracrable stern or bow thruster

    Hi,
    I belief I can help. What you need is a so called Voith-Schneider propellor system. This sytem was developed for commercial vessels. A German company Hübner-Braun offers scaled down units for sailboats. Try this link:

    Good luck !

    Hi,
    this link to the site of SPW GmbH in Bremerhaven, Germany is current and offers the Hübner-Braun propulsion unit as a custom-build (apparently not enough orders yet to go to series production.)

    As they say in Germany, Mast- und Schotbruch!

    Hydraulic Drive

    Not exactly a 'retractable drive' in this particular form on this older catamaran, but being that it is hydraulic in nature it could be.

    Here is a 1975 catamaran that has a single motor with twin props driven by hydraulic power. I think it speaks well of a hydraulic system to have operated this long
    38' Catamaran Sailboat - $30000 (Portland)
