Warning: Woodworking is inherently dangerous. You are using sharp tools some of them spinning at large RPM's. You need to be wearing eye protection at all times, hearing protection as needed and because you are going to be working on some very small pieces you must use a push stick. Niether I or Instructables bear any responsibility if you do something stupid, lose focus, act carelessly, or recklessly.
The same can be said about boating, you should be wearing a life vest anytime you are in a boat and always acting in a safe manner.
The town I live in has a boat building/ racing contest every year. The challenge to this contest is the materials you are allowed to use as well as the ones you are not.
The materials include:
1) 1 sheet of Plywood (any thinckness)
2) 2 8 foot long 2X4's
3) 1 Roll of Duct tape (Essential for almost everything I build)
4) 1 Lbs of fasteners (I chose 1X6 rough thread drywall screws)
You are not allowed to use Glue, Epoxy, Chaulk, Silicone... In short NO adhesives at all.
The boats may be decorated with paint and will also be judged on theme and appearance.
I had paint laying around so my total cash outlay was less then $50
Here is a link tot he Yahoo groups that I got the plan / desgn from along with some great advice. http://groups.yahoo.com/group/onesheetwonders/

Signing UpStep 1: Materials
1) 1 4'X 8' sheet of 1/4 inch B/C grade plywood
2) 2 8" 2x4's (As few knots and a straight as possible, Yeah, Yeah I know) If you are not entering a contest like I was you might want to get a knot free 1x4 for the chine logs.
3) 1 Roll of Duct tape. (Once again if you are not entering a contest like I did get yourself some waterproof adhesive, chaulk and maybe some fiberglass tape and resin for the seams.)
4) 1 Lbs of fasteners, I used about 1/2 lb of 1"x6 coarse thread drywall screws. I f you can get 3/4 inch that will be great for the Chines and Gunwales and Iwales (Pronouned gunnel and innel).
5) You will also need a scrap piece of wood 32" x12" that you will use for a removable form

i will try and get a pic for you to see, we also use them on a small tidal river and use a plank to make a seat to sit higher above the water line.
Good luck with yours and stay safe.

I weigh about 200 lbs and had about 5-6 inches of freeboard.
Good luck and psot a picture when you are done please.
I suppose you caould put two small children in, But I don't reccomend that. I also strongly suggest wearing a life preserver/ jacket of some type.
I pulled the paddle very hard and it didn't tip in eiother the quarry or the pool.
By the way I might build this some day. Nice Instructable!
Good luck with your build and feel free to ask any other questions
I just layed mine on 2 2x4'sand set the circular saw depth for 1/2 inch.
But your method will give it more stability.
That being said The 1/ 4 inch B/ C plywood I used was about $20-$23
The 2 x 4's cost about $5 each(I bought Premium grade to reduce the knots and I spent about 40 minutes going through the pile.
I used coarse thread drywall screws these were about $5. I had to use 1" but 3'/4 would have been preferred.
Primer is about $8- $10 and Paint is $10- $15.
All told about $50.
As far as weight I weigh about 200 lbs witht he paddle life vest about 210 lbs and I had about 4-5" of freeboard.
I also squared and changed the angle on the bow, put a keel strip, made it a bit wider and lowered the thwarts so my kids could sit on them ..
Sadly It was dangerously "tippy" and we didnt even try the outboard.
In the end we just added some rollocks and have been happily and safely rowing on our local river ever since. Here's a pic of my son....Cheers
A keel strip about an inch thick by 3 inches wide, would help a lot with tracking. It would also help with the strength of the bottom.
I might adapt your design to an outrigger sail boat for my kids to play with. I will however use caulking and a little stronger gunal bands. I don't have to follow your race rules. :-)
(1) 2 pieces 8" => (foot?)
(2) 2x4's => (2 inch x 4 inch?)
No need for the metric sizes any more, i can convert them for myself
