SKIFF, 19' X 5', 250 POUNDS EMPTY
Bruce was looking
for a large powered canoe but couldn't find one for sale. He
said they still make them by hand in Maine but he was in California
and you couldn't expect to buy one anyway unless you showed
up with money in hand on the day the builder happened to finish
one. So he wondered if the row/sail skiff Woobo
couldn't be redone as a long lean powerboat. It's not the first
time that has been mentioned. Ray Laviolette had the first plumb
bow Roar, predecessor to Woobo, built up in Michigan for rowing
and both he and his builder thought the shape could be modified
for low power.
pretty quickly from that. I kept the plumb bow, easy to build
and lots of folks like its looks. The multichine shape is very
good in rough water. it's not as stable as a flattie of course
but sometimes I think it is safer in that you must walk on the
center of the boat because you can't step on the slanted bilge
panels. Your weight is always close to centerline where it should
be. I made the main cross section 6" wider than Woobo and
a bit deeper. From the center aft the bottom is straight and
flat. The sides could be that way too, but I pinch them in a
little and sweep the sheer up in the stern a bit for looks.
I gave it a skid/stiffener on centerline so she would stay put
on the water. These multichine boats have little lateral resistance
on their own and sometimes would just as soon go sideways as
I'm a big chicken
on power and would keep this one at 10hp max. I think the main
problem will simply be the weight of the motor, fuel and skipper
in the stern. I've never designed a downward hook into the bottom
to cope with bow wanting to go skyward, although some swear
by that hook. The boat could be trimmed with wedges glued to
the bottom stern if needed.
I kept Woobo's light
taped seam construction and the plywood bill looks like three
sheets of 1/4" and four sheets of 3/8". That's about
250 pounds of plywood and I would expect the finished boat to
weigh about that much. The bow is boxed in with a storage/buoyancy
chamber, the middle has a stout boxed thwart, and the stern
is boxed in with a draining motor well. There are actually two
places in the boat long and wide enough to lie down in. It might
be a reasonable expedition boat given a small motor that burns
little fuel and a canoeist skipper who is used to roughing it.
Brian Nimmo built the prototype:
He brought it to Rend Lake with fresh paint and a new 10hp four stroke...
And I hopped aboard for a ride. He had his gps with him...
Very nice I thought. He will be using it to run rivers. We figured we were at about 800 pounds total. At 8 mph she started to lift on plane and at full throttle was doing 15. She banked her turns nicely, something you can't expect a true flattie to do.
