Thanks, makes sense, one more question - Do you cut or bend these strips to match the curve of the rib?

Is this about the right place for the cut out for chime strip on the ribs with the rounded rails?

Of the two squares you have drawn, the one on the left looks ok - use the outline plan on your bottom deck piece just to make sure you are close to the right shape, and measure to keep it symmetrical. It's real easy to flatten off thè outline on one side just by being a few mm off.

For the rib blocks you can rough cut then sand them to shape once glued. If you have balsa then a craft knife trim would do

Thanks Mike, that helps a lot

Personally I would be tempted to add another chine strip to the left of your two blocks in the drawing, otherwise part of your rail is going to end up quite thin in that area and weakened as a result. The extra chine strip will be very minimal in terms of extra weight but will add quite a bit more strength to that part of your rail. Also, if your sanding is a tiny too but aggressive in that area you risk sanding right through with nothing behind!

That's only my opinion and I am by no means an expert at this!

No harm in that's suppose Sam so a good suggestion.

What deck thickness you going for?

I'm doing mine at 1/4 inch before sanding etc, but it is paulownia which is quite lightweight and a bit weaker than cedar I think so ongoing to glass the inside of the hull and deck with 4oz glass and the do the outside in 4oz too to create a sort of sandwich which is supposed to come out very strong, we'll see!

Thanks Sam. I was thinking the same thing. Also, to add to the potential problem, I am using a 4mm ply for the base, so there isn't much available to sand in the base. So I am going to add the extra chime strip. It is only about 4 or 5 ribs that need it, and as you say it would add much weight.

Mike - I still haven't decided on my deck thickness yet, it depends what wood can I get. I am going wood shopping soon and see what they got. Most likely I will go with standard 6mm thickness everyone uses.

I made my leash plug today, I used the end of an old scrap table leg., the wood is imbuia or brazilian walnut, a nice hardwood so it should be strong.
The metal is 5mm aluminium bar I had lying around, nice and light.
and by pure chance it seems to be perfect size for my 30mm hole saw. :D
maybe a little bigger than that its needs to be but I am happy with it.
took me about an hour to make.
cost = 0
