Scott Jutson has been a long-time advocate of foil assisted power cats and recently released his latest examples.
His 9.5m power cat for an Alaskan client is one of the many foil assist cats operating in Alaska for operators seeking optimal ride quality and fuel efficiency to support long days in rough conditions. The hull is asymmetric with semi symmetric bows and a single delta foil. Trim is semi-automated using ZipWake interceptors. The house has full walk-around side decks with three sliding doors.
Designed as a multi-mission boat for hunting and fishing guides in the Alaskan wilds, this design has a range of amenities that allow it to do what the clients require. There is a hydraulic bow loading ramp for the big game, large fish wells for halibut, and a diesel heating system to keep the chill off.
Scott Jutson reports that the bulk of his work now is with foil assist cats and, more specifically, with single foils. These are used in conjunction with interceptors, which provides a level of automated trim control that is not previously possible without big dollars.
“The main gains are 30% fuel savings at cruise (compared to a non-foil cat), ultimate ride quality in a seaway, and minimal wake wash”, says Jutson.
The basic dimensions of the new 9.5m foil assisted power cat are 9.45m with a beam of 3.35m, displacement of 6.8 tons in half load, and capacity for 850 litres of fuel. The top speed with a pair of Suzuki 350s is 42 knots, with a cruise speed of 30 knots. Fuel burn at cruise is 3.15 lpnm and a range of 250 nm.
Construction is 5086 alloy to Lloyds SSC, with the boat built by Armstrong Consolidated, Port Townsend, WA, USA.
