Hello Borrel
The naval historian John Lambert conducted the greatest amount of research on Coastal Forces craft for his books and model plans, but sadly died before publishing anything comprehensive on the British Power Boat designs - at least as far as I am aware. I don’t know if naval historian and co-author, Al Ross, may hold any details, otherwise Portsmouth City Archives might be the best bet, or possibly the National Maritime Museum for plans.
This film from the
East Anglia Film Archive, which I have pointed out before in this forum, contains some interesting shots at the end of the film, and in colour, of RAF rescue launches which are British Power Boat whalebacks, that would otherwise be identical to a Coastal Forces’ MASB, and which provides a useful insight into their sea-going characteristics.
