Currently being without a boat I am building a little dinghy. The build thread will be on Bateau.com. 

If I enjoy the whole process and at the end of it I get something I don't mind to admitting that I built I may try something bigger...

Use will be for trout fishing canterbury lakes, crossing the Hurunui river lagoon going after salmon, and mucking around Nelson.

Great project, please post updates on your progress.
Those that say it can't be done are being overtaken by those doing it.

Good on you.
Used to be common here in NZ to build your own dinghy. 
We had some great designers supporting home builders plus many keen builders designed their own. In this weather building in shed is better than being on the water.
Look forward to your project.
I have another in the planning stage - an old style clinker built in glued lapstrake.

Nice one.  How does the saw-max tool go on curved cuts?

The saw-max cuts about 2mm wide. Curves are no problem as long as they are smooth fair curves. No problem with the curves for those panels. Router or jigsaw for finer work.

One thing though. I was cutting flat on the floor with cardboard under to keep the concrete from the blade. I did get build up of dust in the cut every meter or so. Easy to clear once I figured it out.

In the 50s and 60s damn near ever garage had a dinghy built in them.. Think it was the old hartley design or out of Popular Mechanics mags
These days things like fixtures/ glues are far superior.
 We made kayak cannoes.. ply off cuts, ripped a few stringers, brass scews canvas and old house paint...Did from Amuri damn to port waikato, Clevedon to Waiheke and back and a few other trips
 Those plans where out of a popular mechanic mag... we where about 14/ 15yrs at the time.

This boat is stitch and glue. Supposed to be fast and easy construction. I'm drawing and cutting the rest of the panels at the moment. Gluing will have to wait until the weather warms up a bit. Too cold for even fast hardener.

Most photos and info will be on the linked bateau thread though I'll keep this updated from time to time.

I can understand why building is going out of fashion. I will have a bit over $1000 in materials in this by the time I'm done.

I've been looking into stitch and glue. Planning a kayak build later this year. 

With the S&G build system specified, the ply ends up completely encapsulated in and joined together by epoxy, so its more or less functioning as a very strong core material.

A bit different to the old glass over ply with metal fastenings.

I had a bit of a play with the epoxy before buying Ply. Incredible stuff. Unlike polyester it is tenacious at gripping to the wood. This will have 400g biaxial on seams inside and out. Paint everything except the bottom which will have an aluminum powder coating.

I was impressed by the look of your SS18 when I saw it. Always thought that that would be too much project for me. If this goes well I'll probably either go for a FS17 with high sides, or decide that one will do me and buy a 5m frewza, Smartwave or something.

I was wondering if it was possible to see the pictures on the bateau thread without a login? I can post some here as well.

Here is a couple of Kiwi stories well worth following.
Both building one of the best 12 footers ever designed.....put 20 hp on it and you have a great fishing and dive boat.

Photos of marking and cutting hull panels.



Excerpts from plans. I paid about $50 for the plans. High school maths and knowledge of coordinates is useful. It would be easier if I had a bigger set square but I am managing with multiple measurements and double checks. Accuracy within 5mm is accepted as gaps can be filled with epoxy putty. Gaps make a stronger final product.

That's a nice 12 footer. I considered building a stitch and glue 12 foot but wanted to keep the size to where it would fit on a garden trailer. With the method I'm using a 14 foot can be made for almost the same cost anyway.

Looking good mate, I'm still toying with building a bateau FS14-LS or FS14.
Where did you source the ply from?

BBS timbers. Roughly $75-$100 a sheet. Seems to be decent stuff. No voids or defects noticed yet.

There were a couple of fs14s on trade me a while back. Make sure that you build the boat you want as homebuilt boats don't sell well. Personally the fs17 seems like much more boat.
