Re: Mark's C21

So the skeg should be at its largest 1 inch wide by 2 inches high beginning 3 feet forward of the center and ending 4 feet before the transom?

Re: Mark's C21

Hello all! I hope you are all enjoying your summer. I've been slowly working on my C21 and I am about to put a skeg on the bottom. I read Jacques's post about skegs, strakes and spray rails. The only thing I didn't pickup on for the skeg was the height. I realize it should start a little forward of ...

Re: Mark's C21

I've never used a grinder before, but I think I can be careful. When you refer to 24-36 grit, you are referring to 24-36 grit sand paper, correct? Do you get mechanical disks that are 24-36 grit or is it like an orbital sander where the 24-36 grit are sand paper disks that stick to the bottom of the...

Re: Mark's C21

Jacques, Guys, Thanks guys for the responses. These areas were wet out thoroughly, but the fabric didn't take it in. I was sweating like a pig hanging over top of it on my scaffold. This is an outdoor build and it was pretty humid the day I was laying this up. I am using the System Three SilverTip E...

Re: Mark's C21

Jacques, So I laid up the Starboard Bottom Panel over the weekend. It appears I have had some wetting out issues on this panel and I am wondering to what extent I need to be concerned about these. If it appears these wetting out issues are potential structural issues, what do you recommend to do to ...
