Revolutionary Catamaran Built with DIAB Core Material

Multimarine Manufacturing has built the composite-based Rapier 550 for Broadblue Catamarans, an entirely new breed of boat designed for fast ocean cruising.

It is described as bringing together a jaw-dropping combination of top performance, high specification and radical new design. With its self-tacking headsail, powered reversing winches and all controls at the enclosed helm, Multimarine say the catamaran is perfect for single-handed sailing.

Multimarine’s Managing Director, Darren Newton, designed the 16-meter (52.5ft) long Rapier 550 which is said to have a cruising speed of 15 knots and a top speed capability in excess of 25 knots. It has recently been nominated for the European Yacht of the Year Award 2015.

On this project, Darren Newton collaborated with Nick Bailey, designer of two previous Multimarine-built vessels. The objective was to create a performance sailing catamaran that was light, yet extremely stable. Multimarine’s solution was to build the boat in sandwich composite material. “We used advanced composite material from DIAB and the latest resin infusion techniques where the hull is made in one shot,” said Multimarine, who add that it is actually the single largest epoxy vacuum bagged multihull ever made in the UK, and yet it is surprisingly light. The entire boat weighs only 9.5 tons, half the weight of similar-sized production boats.

DIAB says that Multimarine has mostly used its material for composite constructions. Darren Newton is very pleased with the technical support he has received. "We have worked with DIAB for some time,” Newton said, “but this was the first time we used DIAB’s kitting service to manufacture the core kit for the deck of the boat. Andy Horton, our contact at DIAB, visited us several times to make sure the kit fitted and take adjustments for the next boat."

According to DIAB, the Rapier 550 is now in production and customers can tailor the interior spaces to their requirements, creating different styles from contemporary to sportive, giving them the best of both production and custom construction worlds.
