Hi Tilly,
Nice to see someone putting in the extra effort to get the Hull as per the original boat, and not as the slab sided kits.
and its not an easy job in wood.
Thought I add a couple of pic as they may be of interest:-
a/How to paint it,
b/The Mast details
c/Mast details
d/Close up of non original water canon.
Many years ago Kingston mouldings did the original hull shaped in fibre glass, I believe mtbhulls.co.uk do a fiberglass hull to suit
1/12th 46ft RAF Vosper Firefloat/Crash Tender £92.00.

Have Fun
