TAURANGA-BASED DEMEY YACHTS has two identical 18m semi-displacement Roger Hill designed catamarans under construction for separate clients in NZ and Australia.

The concept from the start was to create an explorer-style platform capable of cruising  long distances with extremely fuel-efficient hulls matched with fantastic seakeeping abilities, combining this with a large spacious interior, cockpit, and work deck built to a very high standard, surpassing what’s available on the production motor yacht market.

Construction is a carbon foam epoxy matrix using resin infusion as the build medium.

The very top deck has a settee area and storage area to house a variety of water toys such as sailing dinghies, SUP and kayaks, there is also a built-in tender garage under the main cockpit floor which houses the custom designed 3.7 meter carbon catamaran tender

Every detail of the interior has been designed in CAD and using both old-school cabinet-making and CNC technology. The interior has been cleverly designed to give virtually 360 sight lines, separate social areas, and a centreline-based helm station.

Power is via 2 x 550hp Cummins engines burning a total of 124 litres per hour at 18 knots giving a range of 1450 nautical miles, dropping down to 10 knots burns 35 litres per hour and a range of 2840 nautical miles. Top speed is 28 knots in lightship mode. Having such small powerplants also brings the added benefit of lower service costs overall


DEMEY Yachts will be offering a 22m version too.
