A new catamaran crew transfer vessel (CTV) design has been introduced by UK-based Ad Hoc Marine Designs (AHMD), which aims to bring a simple no nonsense vessel with a well-proven pedigree to the market.

AHMD’s new South Class range of catamaran CTVs have been designed collaboratively with builder Due South, pulling together a decade of collective knowledge beginning with the original South Cats range designed and produced by South Boats (Isle of Wight) founder, Clive Jeffrey. AHMD worked very closely with the original South Boats on the Isle of Wight up until 2012, assisting Jeffry with the DNA naval architecture and structural design of the South Boats range of CTVs.

The 24m South Class is the first of these collaborations and is essentially a Mk II modernised update of the original South Boats range of CTVs.

“I’ve known John Kecsmar (naval architect, AHMD) since we first met in the late 80s at FBM Marine where we worked very closely together,” said Jeffrey. “We both had an eye for quality and innovation, the principles also at FBM. When I left FBM and formed South Boats, I kept in close contact with John where both he and Nigel Warren assisted me on the technical and structural design aspects of my growing brand of designs at South Boats. We have always remained close friends and it seemed only natural to join forces together again to continue the close working relationship to create the Mk II South Class of CTVs at AHMD.”

AHMD is largely known for its Typhoon Class of Swath CTVs, and has designed more than 50 different types of catamarans over 30 years and conducted significant amounts of R&D into the hydrodynamics of CTV hull forms.

The new South Class range of CTV catamarans is available in a range of lengths and workboat codes carrying up to 12 technicians or up to 36 technicians under the HS-OSC code. They can have varying duties, payloads and speeds designed to suit individual customer requirements.
