Re: [AtkinBoats] Thoughts On Study Plans for Little Silver
- Trust the designer! The 1/2" batten-seam topsides are lighter and stronger
than 13/16" carvel planking (except against punctures). Using 3/4" cross
planking on the bottom wouldn't be any heavier than the double 3/8"
planking, but wouldn't be as strong. If you must use carvel planking on the
bottom, the framing is more suitable for lengthwise planking. But I wouldn't
be surprised if Billy Atkin chose two layers of light planking to make it
easier to fit the planks to the twist of the bottom. Little Silver's
construction is pretty standard for motorboats of her day, and is still a
good sort of construction today -- especially if you need to haul her around
on a trailer.
