Len Imas of the Department of Civil, Environmental and Ocean Engineering at Stevens Institute of Technology has been awarded a grant from the Office of Naval Research (ONR) for the investigation of ultra-deep vee planing hull hydrodynamics.
Once a vessel with a planing hull achieves enough speed, the water pushes against it with a high enough pressure resulting in a force known as hydrodynamic lift.
Aiding the large spinnaker, the lightweight planing hull
and highly efficient foils of the Farr 400, sees it sail faster than the breeze downwind to around ten knots of pressure, where the target boat speed is 9.
The Xtreme is a true planing hull
so it rides higher in the water than traditional tubes and actually displaces about the same as three 24-inchers for similar buoyancy.
The new Cat engines include the C32, currently the largest Caterpillar planing hull
marine propulsion engine, along with the C7, the smallest in the C family range to date.
The deep vee planing hull
form is powered by twin 400 hp marine diesel engines to attain an operational speed of 25 knots and top speed of 30 knots.
Peter Duclos, president of Gladding-Hearn said: We selected the Volvo Penta IPS2 for our next-generation Chesapeake-class boats to improve the performance and the arrangement of planing hulls
like our pilot boats.
