Scotland: Macduff Shipyards has just completed work on a new-design scallop trawler in the under-15-metres class.
The new vessel 'Crystal Dawn' has been built to the order of Islay Crab Exports, and the design was developed in close co-operation with Macduff Ship Design who produced the steel kit drawings and Stability Data.
The 41.79-tonne vessel has a length overall of 14.95 metres, a breadth of 6.50 metres and a depth of 3.5 metres. The hull form is double chine with a box keel for ballast, and also features a bulbous bow. The steel kit was cut in house by Macduff Profilers from cutting information supplied by Macduff Ship Design, and the hull was fabricated in Macduff, and fully fitted out under cover.
The aluminium alloy wheelhouse is arranged over the deckhouse. The steel galley messroom is accommodated across the transom of the vessel, with a short deckhouse forming the entrance, toilet and shower room and engine-room companionway and escape. A steel whaleback is arranged forward, with a central shelter strip extending from whaleback to deckhouse.
The main engine is a Caterpillar 3406C, rated 186kW at 1,800rpm, with a Reintjes WAF374 gearbox, driving an 1,800-millimetre four-blade propeller in a Rice thrust nozzle. A Mitsubishi 6D16 auxiliary engine is fitted on the port tank top to drive the main hydraulics. A Beta Marine 18kva 240v generator is fitted on the starboard tank top providing power for tools and limited AC circuit on board. All engines are heat exchanger cooled.
The deck machinery package incudes two Macduff split trawl winches, two Gilson winches, two pull down winches, a landing winch, two conveyors and two hydraulic tipping doors. The Gilson arrangement amidships can handle eight dredges per side, and control is arranged from with the wheelhouse. A steel foremast is arranged on the whaleback, with a steel landing derrick.
