The Canadian Coast Guard has officially commissioned a new locally built Search and Rescue (SAR) boat to operate in the waters of the Atlantic Ocean, just off New Brunswick.

CCGS Shediac Bay was acquired by the Canadian government in May 2022 as the twelfth of 20 new SAR boats named after geographic bays across Canada, hence their alternate Bay-class designation. In the case of the new boat, it is named after part of the waters of the Northumberland Strait just off New Brunswick.

The aluminum-hulled SAR boat was built by Hike Metal Products of Ontario to a design by naval architecture firm Robert Allan Ltd. The design is a development of the Severn-class lifeboats operated by the UK’s Royal National Lifeboat Institution (RNLI). Improvements include larger size, greater reach and specific design elements to cope with the extreme weather conditions encountered year-round in the waters off Newfoundland and Nova Scotia. The boat therefore has self righting capability and is durable enough to withstand 12 meter seas and Beaufort Force 12 conditions.

Shediac Bay has a length of 19 meters, a beam of 6.3 meters, a draft of 1.7 meters, a gross tonnage of 75 and a crew of four. Two MTU 10V2000 M94 diesel engines which each produce 1,200 kW drive fixed pitch propellers to provide a maximum speed of 25 knots. Extensive noise and vibration reduction measures have been implemented throughout, including resilient mounts for engines, gearboxes, exhaust silencer systems, vent air intake silencers, soundproofing deck treatments and insulation measures.

At a cruising speed of 15 knots, the boat can travel 250 nautical miles. However, as part of its standard operating profile, it will be limited to 100 nautical miles from shore. The boat is also configured to maintain a maximum state of readiness for 30 minutes, which means that it will be ready to react as soon as an alert is received.

The hull’s center skeg and aft propeller tunnels develop into flared, hinged bow sections with twin-spray chines forward. The vessel also features a raised aft deck for towing operations, reduced freeboard amidships to retrieve survivors from the water, and generous forward sheer and camber.

The large, well-appointed enclosed deck amidships provides maximum visibility and protection for the crew. A survival space is located forward below decks and the engine room is aft. A bow thruster is installed forward for better maneuverability.

Seating is provided for two additional people such as medical personnel, two survivors on stretchers and up to 12 seated survivors. In support of the vessel’s secondary missions, including maintenance of aids to navigation, environmental response, maritime safety and fisheries management, it will occasionally be used to transport up to 16 people in addition to the crew.

The electronics suite includes two Furuno radars and a Teledyne FLIR rotating thermal camera. A small rear crane is used for the launching and recovery of a small inflatable boat.

Like her Bay-class sisters, Shediac Bay is designed to meet or exceed all requirements of Lloyd’s Register Special Service Vessel Rules.
