If you fancy something different perhaps the Sir William Arnold???
got plans and superstructure templates ( sides only) for her.....enjoyed that build.........something different......got lots of pictures of the real boat too.
I have a friend who is a retired staff coxswain for the RNLI who sailed her back to Poole from Brixham after she had put it to port after her gold Medal rescue of the crew of the Bonita, 13/12/1981( just 6 days before the sad Penlee disaster ).....
The boat had taken such a battering during the rescue that the incumbent Guernsey Cox (from where the WA was stationed )thought he had dislodged one of the engines, and so she needed a checkup at Poole.
My friend said that even though the weather was still poor motoring her on one engine to Poole the day after the rescue, she handled absolutely superbly.......and to quote " was probably the finest lifeboat I have ever sailed".
