Boat bow thruster (hydraulic, retractable) BTMH-R
OCEAN YACHT SYSTEMS
The OYS Vertical Retracting Thruster benefits from the same in-hub technology as the Fixed Tunnel Thruster, whilst allowing the Thruster to fully retract leaving a fair hull with minimal drag. This type of Thruster has a very small footprint so is ideally suited to installation in sail or fore lockers where space is at a premium. This Vertical Retracting Thruster is also very useful where vessels have a deep V profile so the Thruster is fitted higher providing a longer deployment stroke to clear the hull. They can also be fitted further forward than a conventional Tunnel Thruster increasing the turning moment of the hull and therefore requiring less power input. This type of Thruster uses a vertical lead screw and guide rods to raise and lower the unit via a motor and compact belt drive. As with the Swing Thruster, all motors and hydraulic hoses are concealed within the vessel so are not in direct contact with sea water.
