Some explanations:

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?

I think this is wonderful! I love the video when your shoe comes off. You did a really good job! The little dog wants to go with you so much! Cute!
Way to be creative!

Cute! Of course it needs more than the 2x4 to properly finish it....but hey...outriggers? I've seen little boats kinda this shape, being used just fine. Maybe by kid fishing in the farm pond...keep in mind that Howard Hughes made, and flew, his Spruce Goose, _one time_, to prove it could.

Neat idea, but the need for an outrigger kinda defeats the whole premise of the build.

That's a gorgeous project boat! Without plans it sounds like too. Don't care what anyone says, to me it looks great!

Thank you! Now it is a shelf. You can see it here: https://www.instructables.com/id/Boat-Shelf/

So, let I get this straight: You create an astounding piece of beautiful craftsmanship & you cover it with a plastic tarp. Couldn't at least go with, like, varnished canvas or something elegant like that?

You didn't read his comments after the video. Why should we read yours?

I think this comment was really meant as a compliment, alias somewhat backhanded.

I got the complement, but why ruin it with the comment about the cover? StephanP1 took the time to write an explaination about the "ugly" plastic and duct tape so it was easily removed. I was going to give the explanation to stevofhenw but thought why should I when he does not read explanations. I get tired of people not reading everything before commenting. At least have the courtesy to read the opening comments of the auther. Because of your kindness, the next time I am frustrated I will let it go. Peace.
