    The aforementioned Six-Hour Canoe is a proven easy build for a group of eighth-graders .. and even three grown men could probably handle it ok if they don't fight over the screwgun. But frankly its not so complicated you can't do as well by scaling up your own cardstock model. Have fun. :)

    Thanks davhill.

    No power tools allowed though.

    Also a time limit.

    Who said anything about grown men? :)

    We'll have fun, maybe even too much!

    Cheers.

    A nail for a screw pilot and a screwdriver bit on a T-handle or brace and bit will speed things along. Gorilla glue will seal the seams.

    Thanks Hoyt.

    Here are some links to past events.

    Beware, home video and it's not mine.

    Couldn't get the videos on but the still is of the 2011 winning boat built and crewed by the local fire department.

    Some pretty comical boat designs in the video. No matter. Looks like a good time was had by all.

    Tom I think that the video will suggest that double paddles are faster than singles. The first place boat was the better design but the second place boat had superior power application.

    The speed through the water won't have much to do with the shape as 3 people can keep full power going for 300 yards. The race will be won in making the turns.

    Clever man Hoyt.

    You can see the duration is only two minutes.

    Another idea below.

    I saw a cat rig the same in another YouTube competition.

    It went really fast but the guys weren't very coordinated in yaw control.

    Top view. To scale.

    The forward paddles a double blade while the following two, singles.

    Those are 6" X 8' floats that draw 1 1/2' with 6" freeboard.

    Sit on top, sealed pontoons.

    It would be a learning curve to master the handling but it would be straight line fast!

    It's almost THREE times the wetted area of the mono hull.

    The only drawback with the mono hull is the potential to tip.

    Okay, I've got another one for you to decode Hoyt. Thanks.

    Around minute mark 6:20 you can see the speed they're acheiving.

    Of course for a three man it gets a little more complicated.

    Cheers!

    P.S. Still looking for a good plan as per my original post folks.

    A couple of years back...

    For what its worth, Tom:

    http://www.boatdesign.net/forums/boat-design/camping-kid-build-raft-race-28311.html

    This made a fast boat, being so skinny; the 4 little boys really did trounce the adult field. if you are limited to ply, I guess it would mean some more fiddle building the outriggers and beams. Build time? might struggle to make 4 hours if you had to make ply outriggers too...

    Probably not the tightest round the marks tho! - big rudder?

    TT,

    Thanks for that.

    I remember the thread now that I see it.

    I like the idea.

    I have entered a number of similar local build/race contests. Go with one long hull, with two two small outriggers. it will be stable and fast, and fairly easy to turn (put the guy in the back who knows how to use the paddle to turn). Use kayak type double bladed paddles. A mono-hull would likely tip over with three adult guys trying to paddle around two buoys.

    If you can use a couple of water noodles for out riggers, or something similar that you do not have to make, it will make the build much faster. An inflatable air mattress wrapped around a 2x4 also make a fast to build outrigger.

    good luck.

    Thanks for that Petros,

    We have four hours build time, that's not part of the timed race.

    So, building low-drag outriggers isn't an issue.

    I'm torn between the tri design from post # 24 and your concept.

    One issue with out-riggers is when using double paddles (which is faster), you've got to negotiate the cross bar ama supports when paddling.

    But I think if I space them just right, it's doable.
