Davits make light of heavy weather
Davits for patrol vessels that allow rapid deployment and retrieval of a range of high speed workboats, even in sea state 6 conditions, are being supplied to the Japanese Fisheries organisation.
The all-weather Caley davits enable rigid inflatable boats (RIBS) to be held in readiness and launched in seconds. Crew safety is paramount to the davit’s handling system which features anti-pendulation control for pitch and roll damping and reduction of pendulum swing. During boat recovery, the towing boom positions the boat under the davit, eliminating boat yaw, while light auto tension winch control eliminates snatching during recovery.
The davits are being fitted to the Japanese Fisheries patrol vessels Hakuryu-maru, Shirahagi-maru, Hakuo-maru and Toko-maru. Each system comprise a C-frame davit with associated towing boom, central hydraulic power unit and controls. The C-frame davit is designed to launch and recover the patrol vessels’ workboats weighing up to 3.5Te.
Stored in the davit’s integral secure stowage boat cradle, launch and recovery operations are controlled from a single control station, mounted fore of the davit, allowing the operator a clear view of the davit boat and towing boom.
