Roger Hill Yacht Design 16m Displacement Powercat

by admin

Roger Hill is one of the most prolific powercat designers in New Zealand, but his new designs are to be found around the world. He is currently working on more than a dozen powercat designs, one of which includes this interesting 16m displacement powercat.

This long range displacement power cat is for an existing client who’s previous boat was a beautiful sailing cat we designed that was built using the ATL Composites ‘Duflex’ system, as is this new power cat. The sailing cat was sold some time ago due to business commitments and now they are ready to put a toe back in the water and look forward to more time afloat and some long range adventures around the bottom of the South Island in the summer and cruising around the Pacific islands during the winter.

The accent is on comfort rather than speed and plenty of space for two couples to live aboard along with all of the equipment and storage required for long trips in remote places with no easy access to fuel, water, and food. The open fly bridge will be enjoyed when cruising in warmer climates and the inside helm station will be very comfortable when they are ranging south in colder conditions. The lounge seating next to the lower helm and the upper helm will keep everyone on board in touch with what is happening around them on passage.

The displacement hull will be super efficient with the performance calculation indicating 26 knots for 320hp engines and with the clients opting to go for the 400hp 6LY Yanmars the hull form is a bit over powered but the engines will be very lightly loaded through the cruising speed range (15 to 20 knots) and last a very long time.

The boat will be fitted out with all of the necessary equipment and appliances for a live aboard lifestyle and long range cruising, genset, dive compressor, water maker, washer/drier, air conditioning, solar panels, lithium batteries, etc. Fuel capacity is 4,700 litres in two tanks and 800 litres of water.

The structure is entirely foam cored composite with fibreglass skins and epoxy resin built from an ATL Composites pre-made, pre-cut panel system and engineered using the DnVGL standard to ensure that it is a very tough and robust structure. The bows incorporate a sacrificial crash zone and numerous water tight compartments under the bonded in water tight cabin soles in the hulls.

It is being built to NZ survey so that in the future, if required, it can be a commercial charter vessel.
