Supermarine Powerboats: Bespoke Powercraft
Supermarine Powerboats: Bespoke Powercraft

Selected Projects


We worked with Adam Younger design to develop the tooling for a revolutionary 55ft long marathon Class powerboat.

Originally conceived to compete in the London to Monte Carlo Powerboat race, (subsiquently cancelled), it was designed to be a smooth rough water powerboat suitable for long offshore passages.

With a very deep forefoot it can cleave through rough seas giving its suspension seated crew a much smoother ride.

We manufactured all of the plugs, moulds and mouldings; moulded in vinyester and carbon and fully cored, with structural input from High Modulus, it is very strong and quite light.

Now powered by twin mercury Racing Qc4V petrol engines, each of 1650 HP, it runs about 115 MPH. Development is still ongoing to achieve better reliability of the mechanical elements and a slightly higher top speed. New Mercury 8 outdrives are currently being fitted along with a stronger driveline.



We were approached by one of our ongoing customers, Powerboat P1, to design and develop a new one make rib race boat for their worldwide powerboat racing series.

We proposed a 7.5 metre monohull, with no steps to ensure easy handling, tapered tubes, with 5 compartments, and a reinforced cockpit for safety of the 2 crew.

We did all the design work, made plugs and moulds and then built the craft. We tested for CE compliance and mounted the engine, seats and controls.

With over 80 hours of on water tesing, with multiple World Powerboat Champion Neil Holmes,  we then signed off the boat to P1 and they were very happy indeed with the 62 MPH speed from only an Evinrue G2 225 HO outboard.

Many examples have now been made and they can now be seen racing around the World.
