This new design by Roger Hill features a displacement hull with remarkable speed and fuel economy and smoothness of ride.

Consider these figures – The power option of 2 x 170 hp or 2 x 190 hp motors through a straight shaft driveline is giving the following data:

Half fuel, full water tanks but minimal personal gear loading. Sea conditions – half metre chop.

8 knots, 9.6 litres per hour total both engines

11 knots, 16 litres per hour total

15 knots, 26.6 litres per hour total

20 knots, 43 litres per hour total

24 knots, 70 litres per hour total.

For the 60 nautical mile trip from Auckland to Great Barrier Island or Tauranga to Great Mercury Island, cruising at 15 knots would take 4 hours and use 106.4 litres of diesel at today’s cost of about $81!

At 20 knots it would be a 3 hour trip at a cost of $100. (Diesel at $0.77 per litre). Please note sea conditions and boat loading will influence this data.

With twin 270hp diesels the next vessel launched had these performance figures:

RPM Speed in kts Fuel – L/ph
Idle – 680 4.5 1.5
1000 5.9 3.7
1500 8.5 9.5
2000 11.7 21.3
2500 16.1 33.4
3000 19.8 50.7
3500 23.2 76.1
Max-3850 25.7 105.8

The interior features a large double berth forward to port, two singles to starboard, and a single in hull under saloon
