Comment by designer...
Jim has joined his 6mm inner planking sheets by butt glueing
and glassing. This inner length is the critical dimension
which governed the design LOA,
which was a maximal 2 sheets around the inner curve, plus
excess for development. 15.25feet.
This particular build is tight because Jim is using 2400 long
sheets on a boat designed with 8 footers in mind., 8 feet
The 3 inches lost is making itself felt, but was allowed for.
Jim just does not have the luxury of an opportunity to scarf,
but scarfing is a lot of work for a questionable gain, especially
in this non-visible area. Jim has inside coated these sheets
and they'll be fitted next time around.
