Catamaran Uses B3 SmartPac by High Modulus

The latest production boat to be built with the B3 SmartPac construction solution is to be launched at the Auckland International Boat Show.

The Prowler by Logan, a 34ft power catamaran based on a Schionning hull design, developed by Logan Classic Boats, and built by Northland Contract Boat Builders (NCBB) in Whangerei, makes its debut at the show after just 3 months in build.

High Modulus say that The Prowler by Logan shows how the B3 SmartPac solution, engineered and supplied by High Modulus, can help to meet performance and production requirements, whilst offering ease of build, and assuring the owner of good quality. The B3 SmartPac combines optimised yet practical composite engineering with pre-cut reinforcement and core materials, packed and delivered to the builders’ door just when they need them.

Weight saving was a key objective for the design team at Logan Classic Boats, who have developed the Prowler to run on twin four-stroke 60hp engines. Through smart engineering and careful selection of materials, the High Modulus team provided a solution that led to boat with a displacement of just 3.4 tonnes, a top speed of 20+knots, and also meets the ISO 12215-5 Standard for composite construction, necessary for CE approval. It was also important for NCBB to be able to build the boat easily and quickly, so the laminate was designed from the outset with this production requirement in mind. The final specification included 0/90° E-glass for the hull, with Airex foam core in the top sides and Matline in the bottom; and +/-45° E-glass and Airex foam core for the wing deck.

NCBB produced the first boat within the short time frame of just 3 months. ‘We had a quick turnaround on hull number 1 and we want to shorten our overall leadtimes – but we don’t want to compromise on quality,’ says Fraser Foote, Managing Director of NCBB. ‘With the B3 SmartPac, we are not only able to benefit from High Modulus’s composite engineering expertise to help meet performance objectives, but we are seeing a range of production benefits too. The reinforcement and core materials are CNC-machined by High Modulus to the exact size and shape required, and pre-labeled so we know where each piece fits, enabling us to reduce the lamination hours required for each boat. And due to the construction manual and quality controls that are integral to the system, we achieve a far greater consistency of quality than ever before.’
