Coastal Motor Boat Replica

Here is something which you won't see too often, an upside down WW1 Coastal Motor Boat!

No 4 Boathouse at Portsmouth are restoring the original CMB 4 which served in WW1 and on secret operations in the Baltic afterwards where she sank the Bolshevik cruiser Oleg. The vessel is on loan from the Imperial War Museum. The Boathouse is currently constructing a full size replica and the hull is currently upside down while final shaping takes place. This gives the opportunity to admire the sculpted hull form and the 'step' which assisted planing. Not sure what wood they are using but it looked lovely!

I'm looking at suggesting an article on the Boathouse to Lindsey as I think it would appeal to a lot of modellers as:

• Vessels owned or being worked on include several very popular modelling subjects
• Woodworking techniques are full size counterparts of how many of us build our own models using wood
• Mixture of boats being worked on and operational vessels.
• Lots of historical associations.

Didn’t know they had a stepped hull?

Yes, we saw it at Chatham Ashley!

Would be nice to go back.

I've got a close up of the step on the Chatham boat!

Vic Smeed's Model Maker Manual has a photograph of a boat which puzzled me mightily until I read about CMBs

Hi there, for anyone interested this link - hope it works - is to the build on British Military Powerboat Team website

I believe the timber used is Iroko wood and also it has been covered with an Epoxy Resin similar to the West System

My CMB model that was made from a free plan in Marine Modelling International April 2008, built by Mr Keith Hayes.

Wasn't this CMB on display At Gosport at the southern end of the Pneumonia bridge years ago, Possibly in the 70s
