Broker's Comments

These boat details are subject to contract.This Jefferson 66 of 1988 is a Grand Holiday home on possibly one of the best mooring positions at the Marina.
It has a huge hydraulic swim platform large enough for a small Ski-Boat to be lowered easily from the stern, this stretches the overall lenght 71 feet.
Four good sized Berths with a large separate Galley, saloon table for that communal breakfast feast .
All cabins have a telephone communications system, so no ly-ins for the Crew.
Power comes from two rebuilt 2006 GM Detroit Diesel 735hp engines to get everyone out to sea swiftly.
The Owners have spent heavily on this cruiser and is a real credit to them, it simply has everything and more………..
The Super-sized Fly-bridge has seats all round which have been re-covered together with the huge enclosed cockpit cover.
At the stern a crane, enough room for a large Jet-Ski and tender that can be lifted onto the water/out again.
Early this year Newly fitted powerful 25hp hydraulic bow/stern thrusters at a cost of approx 40,000€ make this vessel a pleasure to drive the owner tells me even in difficult conditions,allows manoveurability either on/off the dockside,making it capable of being moored within its own length.
Why have an expensive apartment overlooking the Marina, when for possibly a lot less you can have a Manor house slap bang on it.
It was surveyed in 2004 in the United States before coming over to the Algarve, note that the Tenders are going to be kept by the owner but may be negotiable separately.

Note: Part exchange for a smaller vessel may be considered.
