Converting a manually operated furling mast is quite easy. Basically, the vertical shaft in the original line driver is replaced for a longer version which is connected to the motor. A clutch allows the motor to be disconnected for manual operation, if ever needed. The motor is completely integrated in the mast and connected to the Seldén Power Supply and SEL-Bus system.
This video shows the convertion of a Hallberg Rassy 37 mast. The owner is using a Seldén Electric E40i winch for the outhaul to get Synchronized Main Furling, SMF. We suggest you watch that video too.
