Hoc Marine Designs Ltd (AHMD) has announced its new South Class range of
catamaran CTVs. AHMD is mostly known for its world leading Typhoon Class
of Swath CTVs. However, AHMD has designed more than 50 different types
of catamarans over the past 30 years and is conducting significant amount
of R&D into the hydrodynamics of these hull forms. However, despite
its vast catamaran design database, AHMD has taken the view: why reinvent
Unknown to many, AHMD worked closely with the original South Boats Ltd.
on the Isle of Wight until 2012, assisting Clive Jeffry with the DNA naval
architecture and structural design of the South Boats range of catamaran
CTVs which included designing their now famous flexibly mounted deckhouse.
So it seems only natural for AHMD and Clive Jeffery to team up again. Clive
Jeffery heads up Due South Designs Ltd and has collaborated with AHMD where
both see the need for a simple no nonsense catamaran CTVs with a well-proven
provenance and pedigree which the company believes is missing from the
current CTV market.
AHMD has designed its all-new South Class range of CTV catamarans with
Due South Ltd. based upon their collective knowledge and over a decade
of customer feedback into the original range of South Cats by Clive Jeffry
at South Boats Ltd. The 24m South Class is the first of these collaborations
that is the essentially a MK II modernised update of the hugely successful
original South Boats range of CTVs.
In his own words Clive Jeffery says “I’ve known John Kecsmar since
we first met in the late 80s at FBM Marine where we worked very closely
together. 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”
The first-in-class South Class boat is expected to measure 24m in length,
though the series is available in a range of lengths. Those boats in the
UK Workboat Code range will span 15-24m in length and will carry up to
12 turbine technicians. South Class boats designed to HS-OSC Code specifications,
meanwhile, will be able to accommodate up to 36 technicians aboard vessels
sized up to and beyond 24m where the loadline length is no longer an issue
when incorporating the HS-OSC Code. For lengths in excess of 24m loadline,
a maximum number of 60 technicians is possible, as per the HSC-OSC Code.
The maximum capacity for boats in this class will be 45 tons, including
a maximum 20 tons of cargo on a deck strengthened to 1.5 tons per m2.
Speeds offered are in the region of 20-30 knots, depending on payload and
