Nice Capt Bob that explanation makes a lot of sense. I see what you mean by longitudinal strength. I am going to beef them up a little, but I'm still leaning the route without foam.

Well as any good c & p guy knows, your design is as only good as its attachment so no matter how much you beef it up, how you stick it to the hull is what really matters.

In reality, we have seen several builds where the stringers are still sound even with soaked foam, only to be detached from the hull bottom.

Good luck. :thumright:

Yes going with the 3/4 inch marine ply doubled up. I have already cut the first piece and discovered I have a little more grinding to do in the bottom corners. Also a little outward bow in the skin. What do you think of the crown? 37 inches from the keel.

Also a little outward bow in the skin.

That is not good. I would recommend that you make some structure to reinforce the transom skin. For example, a sheet of 1/2" with some straight 2"x 4" backers. Do not allow that bow to be incorporated into your transom, it is an indication that some other surface is out of shape in your hull.

I like the look of your cap mock up. I started to glass my transom and have let the glass run high. I am still playing with the crown ht on mine. I will cut the outer skin after I install my core. Maybe this weekend.

North I plan on doing the same, I cut my transom core and couldn't get a smooth line. Can't wait till I have to cut the ark. Should be comical.

Temporarily attach a batten across the back with the curve you want to guide a skilsaw base.     Probably take 3 passes while increasing blade depth.  And you can angle the base to compensate for the transom angle to make the top of the core flat too...

Dirt, a skill saw like a circular saw? I never tried to cut a curve with a circular saw.

Yea just use a blade you don't like :mrgreen:

Itll cut fine as long as you don't have a huge curve (which you wont judging by crown youre after).    Just make your first cut pretty shallow and increase your depth with 3 passes or so...
