The BLUEWATER  28 AND 31 provide a dryer, smoother ride in rougher weather.

Bluewater 28-31

As a safety boat for the forthcoming Olympic yacht events off Weymouth, we expect "quite a big audience" to view our new design, a semi displacement fast craft – the Bluewater 31.

Delivered recently to a boat charter business CJ Marine of Weymouth, the Bluewater 31 is a “whole new concept as far as we are concerned,” said boat builder, Gary Wiltshire. With their aim to one day have the firm’s own design, Gary Wiltshire and Plymouth charter skipper Graham Hannaford formed Blue Water Boats in 2003; they have over fifty collective years of experience in fibreglass boatbuilding.

“We wanted a boat designed with our guidance, one to become a trademark of our name, and after recent sea trials of the first Bluewater 31 it has surpassed our expectations,” added Gary Wiltshire. “Perhaps its nothing new to have a fast boat of that size, but prior to our boat hitting the market we saw nothing other than quite old designs; we saw a demand for a new style of craft, one to deliver a realistic cruising speed with good fuel economy, that is a critical factor, fuel is forever rising in price. Owners of the craft, our previous customers have chosen to name it Bluewater and that is rewarding.

“About two years ago we approached boat designer Henry Millington and in conjunction took considerable time to get exactly what we all considered the boat to become, one to compete in the same market as other fast semi displacement hulls. Our knowledge is very much in that range of boat, although, we have built trawlers, survey boats, windfarm boats, commercial diving boats, fast potting boats – we can build any sort of GRP boat.” Having an overall length (OAL) of 31ft, the craft comes under the 10m OAL rule for inshore fishing, and a Scottish shellfisherman has already clinched an order for a Bluewater 31. Having a beam of 3.4m and a draft of 0.9m the spacious Bluewater 31 appeals to a wide span of leisure and commercial users.

“When travelling at a realistic cruising speed in moderate to poor weather we wanted a boat that is comfortable, with fuel economy being of prime concern,” explained Gary Wiltshire. “We are not in the game of claiming top speeds. Some firms boost their similar product by saying 30 knots or more, but let’s face it, who would want to travel in even moderate weather at that speed, a boat may cope with it but those on board would not tolerate it. On sea trials the Bluewater 31 went beyond our expectations and at 2400rpm from an Iveco N67 450 engine (330kW at 3000rpm) – and that’s a big engine for this design – it made a cruising speed of between 18 and 19 knots. We had a top speed of 26.2 knots, with 24 to 25 knots as a consistent rate. At 16 knots we measured a fuel consumption of 40 litres/hour.”

The Bluewater31 wheelhouse.

With “plenty of lift” from a multiple chine hull (comprising of one half-chine, one full-chine and above that a reverse chine to reflect the water) the Bluewater 31 gives a dry ride and has a traditional deep keel allowing it to safely dry out in tidal harbours, “that’s often more common than skippers who may luckily have deepwater berthing,” explained Gary Wiltshire. “We are delighted with the recent sea trials of the Bluewater, the design has shown it’s merits, and on this particular deck arrangement it has 15 square meters of open space, its a lot bigger than a similarly laid-out competitor, and will easily take 12 anglers and two crew rather than ten anglers and two crew.

“The Bluewater is quite heavily built and has a relatively big engine, yet to retain that (or better) fuel economy and provide a similar cruising speed, we may recommend saving weight in some areas of the build allowing 350hp or even less to provide the same figures; all of the boats we manufacture are built in excess of Seafish and other scantlings, so it’s really up to the skipper what configuration he wants. “We measure a realistic cruising speed in light of how many anglers (or divers) plus all their gear you can sensibly and comfortably carry. We wanted a boat that could steam at 18 to 19 knots all day and every day burning as little fuel as possible, and that’s what we have.”

Having produced a range of moulds for the wheelhouse, compartments, gunwales and a further range of options, the Bluewater 31 may attract home-builds, the firm owners expecting many orders to be chosen as kits. While most commercial skippers, for extra space may choose a forward leaning wheelhouse, more traditional users who call for a rear facing ‘sport’ wheelhouse are pleased to hear how the firm has moulds for both options.

GRP composition.

The composite deck and hull were moulded using Scott Bader’s Lloyds approved Crystic® 2.446PALV back up resin in combination with dark blue Crystic 65PA gelcoat for the hull. However, for the white gelcoated fibreglass deck and wheelhouse of the Bluewater 31, Crystic Permabright has been used, which is Scott Bader’s new marine approved D-Iso/NPG high performance UV colour change resistant gelcoat. The unique D-Iso/NPG polymer resin chemistry used in Crystic Permabright gelcoat is a step change technology that has set a new standard in long term UV weathering performance for marine applications. It is proven to provide significantly improved colour stability over existing white and cream coloured marine Iso/NPG and Iso gelcoat gelcoats currently on market.

Crystic Permabright gelcoat has now been specified by Blue Water Boats for all white and cream hulls and decks as part of their quality improvement focus. Gary Wiltshire, Director and co founder of Blue Water Boats explained: “We have been amazed by the significantly brighter and glossier finish we can achieve with Crystic Permabright, which has also been easy to handle in production. We have confidence in the product quality and long term performance of this new Scott Bader gelcoat to help keep Bluewater boats looking good for longer.”

Crystic Permabright D-Iso/NPG gelcoat, available as either a spray or brush applied gelcoat, uniquely has a deconjugated polyester backbone in the base resin, which is formulated with ‘best in class’ UV protection additives and selected pigments in white, off-white and cream colours. All the pigment pastes used in Crystic gelcoats are proprietary, manufactured by Scott Bader using their in-house milling and mixing facilities. This advanced deconjugated D-Iso/NPG polymer chemistry developed by Scott Baders’ R & D team significantly outperforms established gelcoat technologies. Independent 12 month Florida UV weathering test results obtained by Scott Bader conclusively demonstrated that a white or cream Crystic Permabright D-Iso/NPG polyester gelcoat is able to provide two times better colour stability than the next best in class Iso/NPG gelcoat and four times better than a standard isophthalic gelcoat.

The roof of the Bluewater 31 wheelhouse is bonded on using Crestabond® M1-30, which is a primer-less, methacrylate structural adhesive, also developed and supplied by Scott Bader. According to Gary Wiltshire, they have been able to save costs and achieve a stronger wheelhouse structure by using Crestabond instead of multiple mechanical fastenings with a flexible gap filler. Crestabond products are universal structural adhesives, designed to bond GRP as well as a variety of metals and plastics. The unique benefit offered by the Crestabond range is that there is no need for lengthy surface preparation, such as grinding, or the application of a primer. Crestabond can be applied by cartridge hand gun or a pneumatic dispensing gun for larger volume requirements.
