9.75m Bow-Cockpit Pilothouse D-RIB Design #108

This is another RIB design in the 9 to 10m category, arising as a result of an open tender under the auspices of Public Works and Government Services, Canada. We were awarded the contract in conjunction with Kanter Marine Inc, Ontario in late 2009 and one boat was designed, built and delivered within the required timeframe.

Looking at the General Arrangement it is obvious that we have a lot of time invested in this design, in order to satisfy the multitude of often conflicting requirements of the technical specification. Features of this boat include the D-tube configuration with solid alloy bulwarks backing up the inflatable tube in both the fwd and aft cockpits. There is good access to the forward cockpit via bulwark cap alongside the house and cuddy cabin. Plan view again shows the rounded bow which is a feature of our recent RIB’s designed for patrol and rescue services in Canada.

The Cuddy cabin is relatively small on this design and is used for storage only, unlike several other bow-cockpit designs we have done in which there’s one or two berths forward of the main cabin (pilothouse) area. There’s no access to the cuddy from the bow cockpit but this can be easily included next time around.

That being said the pilothouse is rather spacious on this wide body vessel with a floor area of 6.3 square metres. all occupants are seated on shock-mitigating seating by Shockwave, B.C. Minimum headroom in the pilothouse is 6′ 4″.

The vessel is powered by twin Yamaha F350A outboards which are capable of pushing the vessel at operational load (~5500 kg) to over 48 knots.
