22.4 metre cray boat

New cray boat under construction for Geraldton lobster fisher

Geraldton-based David Perham is the latest operator from the Western Rock Lobster fishery to order a new crayboat from Dongara Marine.

The 22.4 metre Southerly Designs monohull will, like other recent fishing and pilot boat newbuilds, combine an aluminium hull and composite superstructure.

Dongara Marine has overall project responsibility for the vessel and we are currently fitting out the hull, which arrived in Port Denison in November 2019 after being fabricated in Geraldton. This includes all the main machinery as well as the many mechanical, hydraulic and electrical systems that go in to a modern cray boat.

Dongara Marine has also manufactured the resin-infused composite wheelhouse structure, which is also now in the fitout stage.

Once the wheelhouse and hull fitout stages are complete the superstructure will be lifted onto the hull just prior to the new boat’s launch, which is scheduled for April 2020.

Twin Scania DI16 072M, each rated to 662kW (900hp), will drive fixed pitch props via ZF gearboxes. This is expected to give a maximum speed of around 23 knots and 17 knots cruise.

The new boat will have live tank capacity for 90 baskets of crays, 7000 litres fuel capacity and 800 litres of fresh water.

“Due for launch in April 2020, the new boat will replace Perham’s current vessel, the 58 foot Natural Selection, which was built in 1994.”
