Further to Malcolm's earlier post, many Vic Smeed (& other authors) books are now dated, building materials, finishing materials, r/c, motors, electrics and batteries have all changed.
If you are looking at a cabin cruiser, in the 65th Anniversary Model Boats special edition Dave Milbourn wrote an article which updated one of Vic Smeed's early designs 'Twinkler' to a modern standard. A plan (MM2102) is available. Photographs of the finished model are on this site under the 'All things floating' heading and the thread is 'Vic Smeed's Model Boat Designs' and just wade through the thread (near the end I think).
