Abstract: A retractable thruster assembly for a marine vessel has a propeller unit, a motor, a housing and a drive shaft linking the motor with the propeller unit. An actuator is operable to move the propeller unit from the storage configuration to a deployment configuration in a direction from inboard to outboard, the propeller unit being extended from the hull for use in the deployment configuration. The drive shaft comprises a motor-side universal joint for attachment to the motor and a propeller-side universal joint for attachment to the propeller unit. The universal joints permit folding of the drive shaft at least in the storage configuration. A motor-side telescopic section is disposed adjacent the motor-side universal joint. A propeller-side telescopic section is disposed adjacent the propeller-side universal joint. An intermediate telescopic section is disposed between the motor-side telescopic section and the propeller-side telescopic section.

Abstract: A gypsy is disclosed, adapted for mounting in a windlass for hauling and/or veering anchor rode. A chain-engagement region (12) of the gypsy comprises chain link pockets (18) sized and spaced around the chain-engagement region to engage with chain of the anchor rode. A line-engagement region (24) is provided, with an array of rope grip features (26) spaced around the line-engagement region. The chain-engagement region of the gypsy is formed from a polymeric material and the line-engagement region is formed from a metal material.
