AF3 plans come with two sailplans: the original sharpie
spritsail (as seen in the photo below) and a balanced
AF3, CUDDY SHARPIE, 16' X 5', 250 POUNDS
The AF3 (the original design study was
called "Alison's Fiddle") prototype was built
by Herb McLeod of Edmonton, Alberta, with 70 hours of labor.
He used spruce exterior plywood made at the plant he has
to drive past on his way to the lumberyard.
The sail rig is the exact one I used on
my old Bolger Jinni and it also found its way onto the Pencilbox
design. I align the sail area directly above the trailing
edge of the narrow leeboard on sharpies. If weather helm
becomes a problem (hardly ever happens) you can dial it
out by sweeping the leeboard aft. Traditional teaching would
have the sail much farther forward but that guarantees lee
helm in a boat like this. I'll bet the old rule about "lead"
in sail layouts applies well to the sharp deep cutwater
hulls of traditional planked boats.
Also I've shown external chine logs on
AF3 and all my sharpies. They are an easy, quick, and strong
bottom attachment, but many can't accept their looks. Use
traditional interior logs if you wish. Better yet, use epoxy/fiberglass
tape chine joints with a healthy interior radius. That makes
for a really clean looking boat and the worst rot area in
a wooden boat, that chine log, is totally eliminated.
AF3 is suitable for camping one person
in its cabin and there is not a lot of room in there. If
you would like a larger version of it try the 18'
Normsboat or the 20' AF2
that you can find in the online catalog.
AF3 uses six sheets of 1/4" plywood
and two sheets of 1/2" plywood.
There are some other AF3's out there and
I think I can include all the AF3's I know of. Herb's friend
Gordon built this one:
Remember Frank SanMiguel
Pierre Yves Gabi built
this one shown with the Swiss Alps in the background:
Max Wawrzyniak built this
one in St. Louis:
AF3 uses six sheets of
1/4" plywood and two sheets of 1/2" plywood.
