"I recently completed some proving runs on the Craig Loomes designed 23m wavepiercer tri-maran built by Diogene Marine in Mauritius.
"I was one of three New Zealand boat builders involved in a training and supervisory role in the construction of this innovative new boat. Our first passage involved a 260 nautical mile journey in open ocean between the islands of Mauritius and St Brandon and we left with the boat fully loaded with fuel, water, provisions and crew.
The vessel averaged 20 knots in sea conditions that varied between 2 and 3.5m. Testimony to the boat's ride qualities is the fact that apart from the on watch crew, all passengers slept comfortably, despite the boat maintaining a relatively high speed in moderate seas.
The Seafury surface drives performed perfectly, propelling the boat to a sprint speed of over 30 knots, but also allowing slower passage making speeds of just 15 knots when required.
Maneuverability is excellent - the autopilot handles the helming duties at speed in the rough without problem and although one of the negatives often attributed to surface drives is poor backing performance, reversing of the boat is good - as would be expected of a shaft driven boat."
