Ker Design has experience with most types of commercial vessels and most classification societies. Using advanced software, Ker Design produces designs for steel and aluminium construction that can be assembled very quickly by a semi-skilled or mix-skilled workforce. All our designs are assembled three dimensionally in the computer, both to ensure that the design is free of snags and to create illustrated booklets that show the yard the construction sequence. A high proportion of the office have a background in Fast Ferry design ranging from wave piercing catamaran car ferries through to fast passenger ferries and including a round-the-world record breaking trimaran. With experience in one, two, three and five hulled craft in Composite, Aluminium or Steel and at speeds ranging from 7 to 70 kts, we are in a position to consider almost any challenges that are put before us.

TEAL was designed for the Fathoms company as an 18.25 LOA multi-purpose Catamaran workboat vessel that can be utilised extensively around the coast of the UK and Europe as a workboat, support vessel or for charter. She is capable of working up to 150 miles from shore or for close-to-shore work as required and is capable of undertaking many tasks.

TEAL's special features and gear include a four point mooring system and low speed manoeuvrability (a feature that is particularly useful when carrying out Survey tasks).

TEAL is powered by two Scania DI12 41M engines, each rated at 410hp. The engines drive conventional handed open propellers through Twin Disc MG5114 SC gearboxes to allow TEAL to achieve a maximum speed of 12 knots. Electrical power is provided by a 32 kVA genset. 12v and 24v DC power supplies are also available. TEAL if built of heavy duty steel (with 8mm steel aft deck) and carries both a 10 ton A-Frame designed by Ker Associates and a 18tm HIAB.

Her ample accommodation features a galley, shower and heads. Berths are provided for up to 4 crew when working on extended and overnight operations. Her multiple roles can include dive support, salvage, cargo recovery and debris clearance; hydrographic and geophysical operations, environmental and scientific studies, ROV operations, personnel transfer/cargo supply operations, buoy laying and general workboat duties.

Ker has been subcontracted to undertake the realisation of several roofbox design concepts created for sale by Thule and Halfords. Ker Associates used advanced surfacing modelling techniques to produce the shapes which were then sent off for tooling by CNC.

Ker carried out hull design and stability calculation for the Sealander amphibious vehicle. It is in service ferrying up to 46 passengers to & from a small island off the Cornish coast in England. The owners here required the vehicle to be a lifeline to the main land even when their fleet of smaller passenger boats were unable to put to sea. The final specification included twin engines, two hydraulic lift stairways and a disabled person's lift that doubles as a cargo loading platform.
