The BISCAYNE 18 & 22 classic mahogany runabout designs
capture the look and feel of production runabouts built in
the several years either side of 1940, and incorporate
similar hull shapes accordingly. That means reverse-curved
flaring topsides at the bow blending gracefully aft to a
generous tumblehome at the transom. Such attractive contours
are impossible to build using sheet plywood alone, yet easily
reproduced using our carefully detailed building methods.
Also, notice the gentle reversed sheer profile lines of these
designs. They incorporate enough "heft" within the
specially-designed structure so you can create that soft
"rolled edge" gunnel. That's a prime feature
giving these boats the elegance missing in more
"ordinary" runabouts of similar size. Couple this
with the authentic "plumb" stem and careful
cockpit/deck detailing and you have a boat with true classic
authenticity.
But beyond the authentic styling of our Biscayne 18 & 22
is both a superior boat and one that will cost a fraction of
a new replica or restored original. It's all due to our
modern wood-epoxy "cold-molded" planking method
that prevents leaking joints and flexing hulls that can
detract from performance and longevity. If boats of the past
had had such technology, they would have been built this way.
Using double diagonal ply/veneer planking, there are no
rabbets to cut, no steam bending, no caulked seams, and no
lofting. Bottom thickness totals ½" (four layers)
with 3/8" topsides (three layers with the final
appearance layer applied lengthwise). Planking is reinforced
inside by a series of longitudinal stiffeners wrapped around
a series of husky sawn wood frames and other backbone
members. The result? A stiff, strong, durable yet lightweight
hull that's free from rot and easy to maintain.
Power comes from a direct drive motor located amidships. We
prefer a contemporary power plant over traditional motors
that are sometimes still available because they are lighter
in weight, more compact, more reliable, and offer higher
output for their size. Usually gasoline motors are used, but
diesel is an option as long as weight won't exceed that
of the largest gasoline type that might be found within our
listed displacement ratings.
However, we advise against overpowering these boats;
practical speeds should be limited to the 30's and
40's. And if using longer in-line motors, and/or those
that may be on the heavy side, we would recommend considering
building the longer option hull included with both designs.
This is done by respacing frames proportionately so
appearance features are retained. Shortening these boats,
however, is not recommended.
Plans with instructions aimed at the amateur craftsman
include all the details along with material listing,
fastening schedule, and resource list to help you track down
what you need. Also provided are FULL SIZE PATTERNS for the
sawn frame and backbone members so lofting is not
required.
