World War One-era speedboat replica takes to water off Portsmouth - BBC News

September 14, 2023

A replica of a World War One-era military speedboat has taken to the water for the first time.

The Coastal Motor Boat Number 4 (CMB4) torpedoed a Bolshevik cruiser in action following the Russian Revolution.

A team of volunteers at BoatHouse4 took six years to build this replica from the original plans and have held successful sea trials off Portsmouth.

Volunteer team lead David Griffiths, a retired shipwright, said the project had been "hard work all the way". Landau worked closely with the BH4 team throughout the project and the boat spent 6 months in our secure facility in Marchwood being sheathed, painted and fitted out. Once the engine was installed and steering fitted the boat returned to Portsmouth for final preparations for sea trials.

The original 40ft vessel - now part of the Imperial War Museum's collection - could reach speeds of up to 40 knots and was used to attack much larger ships during World War One.

The craft has a long wooden rack between the cockpit and stern on which a Whitehead Torpedo was held. The crew would have to quickly steer away from danger after firing their torpedo to avoid being struck by it.
