F/V THERESA MARIE93.3’ Steel Cannery Tender — Petersburg, Alaska New Price: $940,000
At $940,000, F/V THERESA MARIE represents an unusually strong value for a fully developed Alaska cannery tender with substantial fish capacity, commercial deck machinery, RSW refrigeration, nearly 32,000 gallons of fuel capacity, and a proven heavy-steel platform.
This is not a lightly converted recreational vessel or an unfinished commercial project. THERESA MARIE is a purpose-built working vessel based on a Bering Sea king crab harvest design and subsequently configured for high-volume tender operations.
Built by Marine Power & Equipment in Seattle, she measures 93.3 feet overall with a 30.8-foot beam. Duwamish Shipyard added eight feet of sponsons and lengthened the vessel ten feet aft of the rudder in 1991, creating a wide, stable working platform with serious carrying capacity.
The vessel is equipped with two polyurea-coated fish holds and an IMS 50-ton, self-contained RSW system. Reported salmon capacity is approximately 230,000 pounds, supported by a Trans Vac fish pump, aluminum de-watering box, sorting table, money fish boxes, weight box, and dual six-inch circulating pumps.
A Detroit Diesel 16V-149, rated at 940 HP, provides main propulsion through a Twin Disc MG 5301 transmission with 6:1 reduction, a six-inch shaft, and a 78-inch four-blade stainless-steel propeller. The indicated engine meter shows approximately 8,661 hours, reportedly since new in 2001.
Electrical capacity is equally substantial. The vessel carries a Detroit Diesel Series 50, 200 kW generator along with a Detroit Diesel 4-71 auxiliary generator. Both are keel cooled and configured to support the vessel’s refrigeration, hydraulics, fish-handling equipment, accommodations, and commercial electrical loads.

Construction
THERESA MARIE has an all-welded mild-steel hull and superstructure with an aluminum top house.
Her hull form incorporates a V-entry, raked stem, moderate flare, pronounced sheer, single hard chine, and squared stern. The vessel is divided by six transverse watertight bulkheads extending to the main deck.
Reported construction includes:
- 3/8-inch steel hull-side and bottom plating

A Serious Commercial Vessel at an Aggressive Price
A vessel with this combination of steel construction, fish capacity, RSW refrigeration, fuel capacity, generating power, hydraulic machinery, crew accommodations, and Alaska operating history is difficult to duplicate.
The new asking price of $940,000 makes THERESA MARIE a compelling opportunity for an established operator, processor, fishing group, tender operator, or commercial buyer looking for a capable platform without starting a multi-year construction project.
