International Recognition for Fast Displacement Hull Form

Galactica Star

Galactica Star, the first vessel to feature the Fast Displacement Hull Form (FDHF), has won the award for the best high-speed yacht over 45 meters in length at the World Super Yacht Awards on May 3, 2014. The jury reported that the award was granted because of Galactica Star’s “technically innovative FDHF (Fast Displacement Hull Form) design, developed by Van Oossanen Naval Architects”. Van Oossanen started the development of this new type of hull form in 2009. This was driven by their passion to develop vessels that are highly efficient both at lower cruising speeds and at high speeds.

Kvichak Marine Building Cummins-Powered Catamaran

"This project represents our commitment to the passenger vessel industry, including high speed catamarans," says Kvichak Marine's Art Parker. Well-known for their 30 to 40-ft. aluminum fishboats and oil response vessels, the Seattle-based boat builder is currently building a 64 x 28-ft. displacement hulled catamaran for Captain Andy's Sailing Adventures of Port Allen on the Island of Kauai, in Hawaii. The boat, to operate year round on the Na Pali Coast, will be rated for 100 passengers on scheduled snorkeling and whale watch day trips. In the evenings she will serve catered meals for up to 40 sit down diners. The main deck house is open to the aft with front and side windows providing shelter while the stern area is open. The top deck carries the pilot house and additional open seating.

Transonic Hull Technology for Offshore Vessels

Hydrodynamics theory establishes that wave making resistance of displacement hulls originate from their body shape, especially from shoulders, midbody, and rear quarter curvatures of their waterplane at the water-air interface.  These curvatures create bow waves, midbody troughs, and stern waves, which set the “hull speed” limit when the distance between bow and stern wave equal the boat’s length (speed/length ratio 1.34).  Above hull speed, resistance grows at a high exponential rate.  Transonic Hull (TH) technology eliminates this problem by using a slender triangular waterplane with apex at the bow, and rectilinear sides, free of curvatures, extending from bow to a maximum beam at the stern.  This shape also generates the sharpest possible entry angle at the bow.

AMT Marine Building Fast Utility Boat at Hope Services

Andy Martin of AMT Marine will take delivery this May of a 136 x 34 x 12-ft. mini-supply boat from Hope Services of Dulac, La. The new boat, designed by Frank Basil's Entech and Associates of Houma, will be powered by a pair of Cummins V-12 KTA38 M0 main engines rated for 850 hp each at 1,800 rpm and driving through Twin Disc MG5301 gears with a ratio of 5.96:1. It's what this combination is driving that makes the story. On the end of each stainless steel six-in. shaft will be mounted a 66 x 54-in. five-blade prop from Padgett-Swan. Computer modelling has shown a gain of up to 1.5 knots with this combination and the five-blade props over four-blade props. Given the new boat's cargo capacities ? approximately 95,000 gallons of water and 90,000 of fuel ?
