boat models I have made

First Water Trial

The boat is together and ready for its first float.

cut down chair on boat floor

The floor is ready and I cut an old lawn chair down. I'm a bit doubtful that using thin plywood is going to work. I've added a few strips of wood to make it stiffer.

folded-coroplast boat.

The boat folds nicely with all the parts inside. I used dollar store straps to hold the package closed. This fits nicely on my bike trailer and was easy to transport. The boat measures 2 x 4 feet when folded.

The boat is assembled and in the water ... floating ... upright!

Getting my butt in the chair was surprisingly difficult. I don't have good knees and the boat is somewhat floppy. Eventually I stepped down from the dock onto the chair and unfolded myself in the boat.

Paddling in the boat

The boat is very light on the water and easy to move. I forgot my kayak paddle so I used my tender oar. Not particularly good for this but it worked.

I had to slide the seat around till I found a good balance.

When I eventually use the oar like a kayak paddle it works quite well.

It's very easy to move and comfortable. I did not put in the supports from the thwarts. They will go in later. I still have to paint and fiddle a few things.

So what do I think about this boat?

PROS: I think this boat is a great success. You have to remember what it is. An experimental minimalist boat designed for quiet waters. It floated well, moved easily in the water, was adequately stable and has a high "cool factor". For about 50 dollars of materials I had a great deal of fun and a lightweight easily transportable folding boat to show for my efforts. Nick and I paid more for fish and chips and beer this week. I don't think it was as much fun either.

CONS: I had trouble getting in. Ok, I'm an old lady with stiff knees. Getting out was easier though.
The boat is smooth on the bottom and so when I paddle it tends to not track straight. I think a proper kayak paddle and better technique would help. I also think that a small panel clamped to the side would help, next time I'll try this.

One technical point, one of the thwarts T Nut started to pull out from the end of the board where it had been epoxied in. I think I will drill a hole in the board and just tie the thwart on and not worry about the nuts. I certainly know how to make boating knots. Right now there is a hole in the hull to allow the fancy bolt through. A grommet could reinforce the plastic and allow a rope to go through. I will also add the stiffeners that I did not have time to add. This will improve the rigidity of the boat, although this is not really a problem.

The Scotch tough tape has been on for about a month and is not showing any signs of coming loose and peeling off. This is good.

I try to be accurate and check my information, but mistakes happen. If you decide to build a coroplast boat remember its an experimental boat and you need to use it in safe water. Wear your PDF and have fun.
