Hull

OFF-LINE is of all fiberglass construction, solid from the

waterline down. Her hull sides, deck, and superstructure

all have balsa cores. She has full cored bulkheads and

longitudinals as needed.

She is a fully molded shape with a box keel and bulbous

bow. Each of the props is on a full skeg. There is a full

steel shoe that runs the length of the keel and steel

shoes on the skegs. She carries 20 tons of lead ballast.

There is an access plate into the bulb. Above the bulb is a

stainless steel cutwater. Immediately aft is the 16" bow

thruster tube.

OFF-LINE Features enormous fiberglass stabilizer fins

measuring 47"X70" or 22Sq. Ft. Each. These fins are

large for a yacht of this size, and provide incredible

stability at slow speeds. They are controlled by Naiads

digital control head

BILGE LAYOUT:

There are 16 stations. Starting forward is the bulbous

bow. The bulbous bow is a separate watertight

compartment. Immediately aft is a watertight bow

thruster compartment with a freeman hatch in the crew

area floor for access. On the top of this compartment is

the crew area floor making this a collision bulkhead that

protects the knuckle of the bow. Aft of the bow thruster

compartment is a machinery space. At the aft end of the

machinery space is a bolted aluminum hatch for access

into the centerline beneath the guest accommodations.

Aft of that is the engine room. Aft of that is the lazarette

area.

There are two main raw water intakes in the engine room

(sea chests). They are fiberglass standpipes with cupro

nickel logs, to witch are attached bronze ball valves.

There are individual sea strainers for each piece of

equipment.

hydraulic bow thruster and one for the hydraulic

windlasses. Also located here is the plumbing for the bulb

bow discharge and fill. Aft is an automatic bilge pump and

tanks have large manholes. In the centerline is the

hydraulic lift for the forward looking sonar. All the way aft

are the two RUUD 30 gallon hot water heaters. Beneath

are two headhunter portable water pumps with soft

starts. Outboard and aft in this compartment are the two

stabilizer heads.

Notes

Off Line was a collaboration of Northern Marine and Delta Marine in the Pacific Northwest. Orginally built with virtually an unlimited budget. Off Line is the only twin engine built in this model.

Off Line is an amazing example of a true expedition yacht built to cruise the world. This owner has maintained the yacht with an open checkbook. I have seen 3 and 4 year old yachts that do not show as well. The interior is comfortable with an air of homeyness about it. The engine room is spotless. Off Line was painted a few years ago. This is a must see yacht
