Patrol and military watercrafts

Southerly Designs has a large database of patrol vessels for a wide range of applications, many of which are in service with government authorities in Australia and South East Asia. New designs are always being added, and we can custom design for any application.

We have proven designs for offshore and harbour patrol, high-speed interception and general patrol craft. Our designs are backed up by proven performance in the field and we have the experience to deliver designs that will exceed the most demanding specifications.

Fishing vessels

Southerly Designs director John Fitzhardinge began designing fishing vessels for the West Australian rock lobster fishery in the 1960s. His designs quickly became the standard ‘WA Crayboat’ and the evolution of his design work, which incorporates the best new ideas and technologies, means Southerly Designs can offer the most modern, efficient vessels to the fishing industry.

We have also designed a number of vessels for deepwater line fisheries, crabbing and fish farming, and have the experience to custom design for any application.

All Southerly fishing vessels feature highly efficient hulls proven at sea by many satisfied fisherman over the years. Built in high-quality marine-grade aluminium alloy to standards that exceed class requirements, a fishing boat built to a Southerly Design is there for the long-haul.

Pilot boats

Southerly Designs has recently introduced a range of Pilot Boats that combine the legendary sea kindly Southerly hulls with innovative features and practical arrangements to facilitate the greatest level of comfort and safety for pilotage operations.

These vessels have been turning heads and impressing Pilots and crew since their debut in 2015, with unrivalled comfort stability and handling.

Our pilot boats feature aluminium hulls that can be combined with either an integrated or resilient mounted superstructure constructed in FRP or aluminium, wide side decks, innovative fendering system and large multifunction aft deck.

Utility vessels

Southerly Designs provides customised solutions for all types of general and special purpose workboats. We have vessels in service for: crew transfer, general cargo, refuelling, live lobster transport, landing craft, harbour work vessels, line handling, and marine survey roles. We can design a bespoke solution for your specific needs or adapt one of our existing vessels.

Small watercraft

Recreational fishing vessels, small utility vessels, RHIBs and other small vessels from 5m-10m are well represented in the Southerly portfolio. The small types receive the same care and attention as all the larger vessels and exhibit the same standards of strength practicality and sea keeling.

Ferries, yachts and tourist vessels

In addition to our core vessel designs outlined above, Southerly Designs has also designed a range of other vessels. These include cat and monohull ferries up to 40m, motor yachts, and tourist vessels.

The designs feature modern aesthetics and practical layouts, backed up by the same attention to detail and solid structural design common to all Southerly Designs.
