Thern Davit Crane and Electric Winch

The Thern davit crane allows rapid deployment of the VFin between the pontoons at the bow of the boat. The winch cable is 200' of 1/4" steel for water column work and 20' of 3/8' steel for coring. The winch motor is powered by 120V, AC power from the Honda Generator. The winch motor was ordered with the control switch on a 18' cable so that the crane can be operated from any position on the boat.
