Hi Phil, thats a nice model. It could be an A Class Destroyer also known as a 27 Knotter from the 1893-4 building programme. Several had three funnels, Spitfire built in 1898 by Armstrongs, Sunfish by Hawthorn Leslie, Surly by J&G Thomson, Conflict by J S White. Or it could be the later Albatross built by Thornycroft.
Also the later turbine powered boat Viper had three funnels as did Velox. Heres a photo of Velox at full speed.
