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 the construction of Chantier Naval Forillon, both in Gaspé, Quebec, Canada is a fine example. . The owners, Listuguj Mi’gmaq Government, expect to accept delivery in April 2022.
The steel hull vessel will have a raised fo’c’sle design with an aluminum wheelhouse. When crabbing, the open rear deck will be able to carry up to 150 100-pound foldable crab pots. When rigged for trawling, a gantry will be mounted on the stern with two drums of net. 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 ship more comfortable for a crew of up to seven people. A bulbous bow, in addition to improving fuel efficiency, will help reduce pitch when working equipment in a swell. A pair of stabilizers will be fitted, following a design originally installed by Chantier Naval Forillon on the Fundy Leader trawler they built in 2006. A number of these systems have since been installed on other vessels. The stabilizer is a simple steel plate, hinged at the bottom of the bilge. It can be hydraulically raised flat against the hull or lowered to a horizontal position. The designer of the boat, Jean-Nil Morissette, explains that they work very well to cushion movements both when traveling and when working on the machine.
Propulsion power will be an IMO-compliant Level III, with Cummins QSK19 producing 750hp at 1,800rpm. To meet IMO Tier III emissions, the QSK19 main engine is fitted with a proven SCR catalyst. The transmission is an MGX-5222 Twin Disc gear with a reduction of 5.04: 1. This will spin a four-bladed Rice Kaplan Skewed propeller with a diameter of 57 inches and a pitch of 67 inches. Attachment confidence is enhanced by a Rice Speed nozzle. This system will give the vessel a cruising speed of nine knots and a pulling force of 8.2 metric tons.
A full set of deck equipment will include a Heila HLM 3-2S deck crane. For the crab, there will be a crab hauler, a crab table, a crab ramp and a 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 to the side of the bulbous bow.
Auxiliary power includes a Cummins QSB7-DM generator set producing 65 kW and an additional QSM11-DM engine producing 355 hp at 1,800 rpm. This engine will drive the ship’s hydraulic pumps and a 65 kW emergency generator. Main and auxiliary engines were supplied by Cummins Sales and Service, Quebec East, Cummins Canada ULC.
The crew accommodation will be foreword in the raised fo’c’sle with the galley and mess in the aft part of this cabin. Holds equipped with RSW 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 for fuel and 7,900 liters for water.
