Alaska 54 Sedan “Watershed”



“Watershed” is a sensational classic semi-displacement motor yacht. Everything about the boat is quality from the solid timber fit-out, the fair finish of the hand laid glass hull, the comprehensive equipment inventory and the general attention to detail. As would be expected, the accommodation is simply luxurious enhanced by ducted air-conditioning and diesel heating.

The twin Cummins diesels (with only 700 hours), bow and stern thrusters accompanied by a remote Shipcontroller system, ensure the boat can be handled by a crew of two.

In 2016, Watershed received a professional electronics overhaul to the tune of $80,000+ (by Island Marine). This includes (but not limited to):
. Full suite of Raymarine electronics with 2x 12" Hybrid Touch screens at the helm
. Cummins engines interfaced with Raymarine
. Glomex WeBoat 4G coastal internet system
. Raymarine SuperHD Color Radar
. Raymarine 60STV Sattelite tv
. Charging system upgrade with new AGM start batteries and Victron 20A charger
