With the regulated catch quotas of contemporary fisheries, the design versatility of a fishing vessel can be important. A new 19.8 x 7.3 m (65 x 24 ft) crab trap and groundfish trawler designed by NAVANEX for construction by Chantier Naval Forillon, both of Gaspé, Quebec, Canada is a fine one. example. Owners, Listuguj Mi’gmaq Government, expect to accept delivery in April 2022.
The steel-hulled vessel will have a raised fo’c’sle design with an aluminum wheelhouse. When crabbing, the clear aft deck will be able to carry up to 150 100-pound collapsible crab pots. When rigged for trawling, a gantry will be mounted on the stern with two net drums. A pair of trawl winches can be mounted on a platform aft of the raised fo’c’sle.
The designers included features to make the vessel more comfortable for a crew of up to seven. A bulbous bow, in addition to improving fuel efficiency, will help reduce pitching when working with gear in a swell. A pair of outriggers will be fitted, following a design first fitted by Chantier Naval Forillon on the trawler Fundy Leader they built in 2006. A number of these systems have since been fitted to other vessels. The stabilizer is a simple steel plate, hinged at the bottom to the bilge. It can be hydraulically raised flat against the hull or lowered to a horizontal position. The boat’s designer, Jean-Nil Morissette, explains that they work very well to dampen movement both when traveling or when working gear.
Propulsion power will be an IMO compliant Tier III, Cummins QSK19 producing 750 bhp at 1800 rpm. To meet IMO Tier III emissions, the QSK19 main engine is fitted with a proven SCR catalyst. The transmission is a Twin Disc MGX-5222 gear with a 5.04:1 reduction. This will turn a Rice Kaplan Skewed four-blade propeller with a diameter of 57 inches and a pitch of 67 inches. Attachment confidence is enhanced with a Rice Speed nozzle. This system will give the vessel a cruising speed of nine knots and a bollard pull of 8.2 metric tons.
A complete set of deck equipment will include a Heila HLM 3-2S deck crane. For crab fishing, there will be crab carrier, crab table, crab dam and crab block. For trawling, in addition to the two trawl winches and net drums, there will be a bag winch. The anchor winch is mounted so that the anchor drops over the side of the bulbous bow.
Auxiliary power includes a Cummins QSB7-DM generator producing 65 kW and an additional QSM11-DM engine producing 355 hp at 1800 rpm. This engine will drive the ship’s hydraulic pumps and a 65 kW standby generator. Main and auxiliary engines were supplied by Cummins Sales and Service, Quebec East, Cummins Canada ULC.
Crew accommodation will be foreword in the raised fo’c’sle with the galley and mess in the aft part of this cabin. The RSW-equipped holds will have a capacity of 60,000 pounds of crab in four sections. An insulated bait hold will have a volume of 7.8 meters. The tank will contain 23,000 liters of fuel and 7,900 liters of water.
