I have no idea on the displacement of Firecrest but she must be fairly similar. The cabin is very nice but does cause a problem in windy weather. With such a lightweight boat, the high sides of the cabin did catch the wind yesterday and cause us some issues. The engine is rated by the builder as a 1/2hp compound diagonal paddle engine, similar in layout to Maid of the Loch in Scotland.
I will post up a couple of videos if that's possible and if I can work out how to.
