Introduction: A Boat From a Single 2x4

First, sorry for my English.
I built this boat for a 2x4 contest. The rules said I can use a real 2x4 , so my 2x4 was 5cm x10cm and 8 feet (240cm) long. The rules said also I can use 10% other material, this is the reason why I covered it with this ugly plastic bag and I used duck tape so I can remove the plastic bag easily after the contest. The design was really bad and I do not recommend it. I made no plan only a little model to get an idea what it should looks like.My biggest mistake was to use a extra board for a seat. Without this seat it should be much better. The weight of this boat is 6,7kg.
Step 1: Sawing
I cut the bar in many thin stripes
The thickest was 8mm and the thinnest was 2mm
Step 2: The Back Frame
The back frame was made with half lap joints.
Step 3: The Side Bars
I cut very thin stripes, I drilled holes in a board, put wooden dowels in and glued 3 stripes together
Step 4: Put the Frame Together
I put the bars in the right position and cut them in length
I glued and screwed everything together. Later I replaced the screws with wooden dowels.
Step 5: the Crosspieces at the Bottom
The crosspieces at the bottom are simple butt joints
Step 6: the Crosspieces on the Side
For the crosspieces on the side I used two piece of paper, put each of them on a bar and sticked them together with tape. I transferred the form to a piece of wood, cut it, sand it and glued it on the frame.
Step 7: The Big Mistake
I thought it is a good idea to make a seat but this was a fail.
Step 8: Cover the Frame
YES, it is ugly!
But it was only for the contest later I removed it!
Step 9: Will It Float?
