Amnesia 1V Design Description

This world cruising, trawler-style vessel utilizes state of the art fuel efficient design technology. Extensively model tested at the University of British Columbia, Canada, tank testing facility. This hull form is designed to perform exceptionally well in a seaway. She has exceeded tank test results in the actual open ocean, heavy weather cruising en-route to California, not long after the initial launch.

Built to ABS Class 1 fiberglass specifications, for unrestricted ocean use and extended offshore cruising. The hull form and bulbous bow are fourth-generation technology. The detailed model test results were used to optimize the proportions of the vessel and combine many years of commercial and pleasure craft design work. The vessel features a round bilge, full displacement hull form with fine entrance and flattened stern sections, incorporates a shallow draft positive flow propeller tunnel for protection.

The controllable pitch propeller maintains ultimate prop efficiency over a wide range of speeds, wind and wave induced loads. The CP also makes maneuvering Amnesia a breeze for one person, at any of the (4) control stations. The owner says he will demonstrate how anyone, can literally “inch” Amnesia into tight quarters, using the infinitely variable CP control, and the 2 side thrusters. This is because of her deadweight and how she sits in the water, which makes her easier to maneuver than his former 75′ twin-engine Symbol motor yacht.

The unique bulbous bow is designed to dampen pitching and increase fuel efficiency. The single 1300 hp MAN diesel with a large diameter 45″ (CP) controllable pitch propeller, provides optimum performance and fuel efficiency, making this vessel up to 30% more efficient than the average production built cruisers.

The owner was a die-hard twin-engine yacht owner for 45 yrs, until he experienced many years, without any propulsion problems on Amnesia. This is due to her sophisticated fuel storage, filtering, and delivery systems. 

Tank tested at a long-range cruise speed of 8 knots, it takes 108 hp to move this vessel along with a range of over 7,000 nautical miles. Top speed as designed and tank tested with the single 1300 hp MAN diesel, is 14.8 knots providing a range of 1700 nautical miles.

At 9 knots including the main generator, she burns approximately 7.8 gph.

Luxury and comfort for the owners and guests, this vessel is finished with a finely crafted Honduran mahogany interior.

As reported by author Capt. Bill Pike, in the 2003 Power & Motorboat Magazine boat test article.

Ocean Trawler 76 "Kookaburra" Design Details

This tough 76 foot steel cruiser is the second of the Working Yachts series, now under construction for a Vancouver, B.C. client. The first 76 was delivered last year after making an 8300 mile delivery trip through the Panama to its San Diego home port.

Each vessel is built to order on a standard hull form and machinery package. Both interior and superstructure layout are customized based on client input and requirements. The first vessel was specifically designed for serious fishing and included two refrigerated fish holds, a built-in live bait tank and room for a very large portable bait tank in the cockpit. Rod holders abound everywhere: in the cockpit and all along the boat deck aft rail.

The interior has been comfortably fitted out in teak, with a master stateroom, 2 guest staterooms, and a crew cabin forward, as well as a roomy main salon, galley and pilothouse. This second vessel has a master stateroom aft, large exercise room and two guest cabins forward. The main deck features wide side decks and includes a spacious main salon, separate dinette, and galley, all made possible by the 22 foot beam. Forward and up 4 steps is the pilothouse with helmseat and settee, extensive electronics, and a convenient day head. It has all the features that have become a standard of the Working Yachts line; heavy steel construction in excess of ABS requirements for Unrestricted Offshore Use, a bulbous bow, fixed or fixed/active stabilizers, model-tested fuel-efficient hull, full collision and watertight bulkheads, and twin screws in protected shaft skegs. Twin 330 hp John Deere engines produce a top speed of just over 12 knots with a long range cruise of 5000 miles at 9 knots. A Working Yacht 80 ft. Expedition and an 85 ft. Pilothouse version are also sold and are starting construction later this year. Working Yachts are available in a wide range of sizes direct from the architects.

Silver Seas Design Description

 Silver Seas is a very successful addition to our line of fast and able ocean cruisers. She is designed to be handled by a crew of two in comfort and safety without resorting to exotic materials or high tech building systems.

     Although Silver Seas approaches the weight of an ultra light displacement boat, she is not lightly built. Her aluminium hull and deck scantlings exceed those set out by The American Bureau of Shipping for Offshore Racing Yachts. The hull form has a short chine amidship above the waterline with rounded sections both fore and aft and a truncated, rounded underwater section. Not only is this form very fast through the water but it is fast and simple to build, reducing building costs. The twin spade rudders are heavily constructed and compliment the twin high aspect ratio keels fitted with lead ballast bulbs at the tip were their weight provides the maximum righting moment. There is 1″ of foam insulation on the hull sides and overhead for warmth and sound insulation but this also gives positive buoyancy, making the boat unsinkable. Watertight bulkheads are located at the bow and stern with addition bulkheads around the engine space to control flooding for the ultimate in safety.

     Light weight has not reduced the carrying capacity. The vessel is fitted with 180 US gallon of diesel, 190 US gallon of fresh water, and can easily carry 2000 pounds of stores without being overloaded. In addition a 150 gallon a day water maker is fitted. The 30 h.p. Yanmar diesel will easily move the boat at 6 knots cruise for a range in excess of 1000 miles. There is a large lazarette for storage of ropes, fenders, propane tanks, dive tanks, etc. Storage access is conveniently reached from the swim step which also accommodates easy boarding from the dinghy or from the water via the swim ladder.

     The Owner’s cabin is aft and features a standard queen size mattress, seat, dresser, night table, and bureau. Access forward is through a port side walk through which contains the shop with freezer built in the forward end. The engine space is alongside under the cockpit with excellent access from each side and forward by the removal of cabinetry panels. The large W.C. is directly across on the starboard side. Up a step is the spacious U shaped galley to port and navigation station to starboard. This area is under the low forward cabin. The large ports are angled to project large amounts of light. The galley has dual sinks on the center island, the non-gimbaled propane stove forward, and work surface with appliance lockers to port. The fridge is build in at the after end. On the starboard side is a wet gear locker and navigation station with room for a computer and all the toys. Directly forward is the entertainment center. The settee/sea berth and dinette take up the forward end of the boat one step down. The large fore peak has plenty of storage space for lighter items. The large deck hatch makes access a breeze. It is matched by a glass hatch over the dinette for ventilation and escape. There are also vent hatches over the galley and navigation. station and a glass hatch over the aft berth.

     The deck layout is clean with wide decks. All halyards and sheets lead to sheet stoppers with all sails are handled from the cockpit. The shrouds are set inboard and there is a permanent jackline on deck for a safety harness. The jib is roller furling with a hanked on staysail on a removable inner stay.
