"Dear Jim, I've got to tell you - that little AF4b of yours is a marvel.
I've logged close to a thousand miles on her so far, through streams,
rivers, canals, bays, sounds, and even one unplanned foray into
the wide Atlantic*; in blazing sunshine, driving rain, wind speeds
over 25k, and temps as low as 30º. Never once has she let me
down." So says Rene Vidmer. Beautiful picture and beautiful job
of building and using a boat.
AF4Breve, POWER CUDDY
SKIFF, 15.5' X 5', 350 POUNDS EMPTY
Bruce Given of Virginia
Beach, Virginia, did a perfect job on the AF4B prototype shown
above. He said he didn't have the shop space to build the 18'
AF4 and when I saw the photo
of him working I believed him. So I scrunched the 18' AF4 down
to 15.5'. I took 1' out of the cabin shortening it to 7', 1'
out of the cockpit shortening it to 5', and 6" out of the
motor well. I'm pretty sure everything is still acceptable,
although the longer AF4 might still be preferred if you can
live with the length. The width and depth of the cabin and transom
are the same as AF4's.
To a certain extent
you could build the shorter boat without new plans by scrunching
up the length dimensions. That method would be a lot more reliable
for a simple flat iron skiff like this one. For more complex
shapes where all the panels are expansions, including sides,
bottom and bilge panels, it would not be so reliable. Bill Wainright
built the original Smoar rowboat by scrunchng up the
Roar2 drawings but he is a sculptor and did the job
with a model. Later I drew Smoar from scratch. Also the bevels
shown on the long boat drawings will not be correct. That might
be no problem with a taped seam hull.
So AF4B is a totally
new set of drawings. There are two changes made besides the
scrunching. I made the bottom 1/2" thick instead of 3/8"
as I built into my AF4. Most folks would prefer the extra stiffness.
On AF4 I think of the bottom flexing only when running hard
into chop. The extra thickness finds its way into a lot of other
parts since they are made from the off fall of the bottom panels.
You could make the bottom from 3/8" ply and save about
50 pounds on the total weight. The second change adds a bottom
to the bow well which lifts the well bottom up about 18".
It is more complex to build but the original deeper well is
hard to reach all the way into. The area below the new well
is accessible from the cabin for an iota more storage.
10 horse power max.
AF4B is simple nail
and glue construction with four sheets of 1/4" plywood
and four sheets of 1/2" plywood.
