The boat was built in Canada in 1939 of the best materials: old growth Douglas fir planking on white oak frames. The vessel has a history as a working commercial tugboat that was used in the coastal trade until about 1965. The tugboat is listed as a British Columbia Vintage Vessel by the Maritime Museum of British Columbia.

It entered private ownership about then. About one year ago the vessel fully sank and was subsequently raised and towed to the shipyard.

It has been extensively repaired over the past year by professional shipwrights. The hull has been re-planked where necessary, and new wood has been installed for guards and and sponsons. The hull has been completely reefed, re-fastened, and re-caulked stem to stern and keel to deck. Decks, cabin sides and roof are in good condition and the roof has had Gaco roof coating applied for waterproofing.

The engine was flushed and pickled following the sinking.

Fuel tank capacity is estimated based on cubic foot size of tanks.

Waterline Boats / Boatshed does not independently verify capacities and measures, which are reported from seller-provided information and/or literature.

Broker's Comments

The time has come for this boat and the price has just been reduced drastically. The boat must be sold now and moved within 30 days.

This historic tugboat offers its buyer a pathway for a restoration at a remarkable entry price. Much of the difficult initial hull and structural work has been completed and the interior is prepared for customization, with a range of possible layouts.

The structural wood issues have been identified and resolved by professional shipwrights. The 1939 hull is in remarkable condition, and the topsides bulwarks and guard rails have been repaired and renewed. The hull has been painted and caulked, and only needs seam compound prior to launching. The topsides have been painted to preserve the structure in a classic white-gray-black paint scheme.

The interior is open and nearly all systems have been removed. Access for installing electrical, plumbing, and mechanical systems is excellent.

The engine could be repaired, or, it could be disassembled and removed through floor hatches and out the back of the saloon. The running gear includes a new cutlass bearing for the shaft.

The boat must be moved now, to provide space for new projects. The location is in one of the best shipyards in the Pacific Northwest for wooden boat restoration. The yard has a 300 ton haul out capacity, and room for the boat ashore. Bring an offer if you are looking for a blank canvas to begin a restoration project of an historic Northwest tugboat.
