That looks all great 8) only thing that I'm not sure about is the support you glued under that cleat in the second picture, it may create a unwanted pressure point,maybe better put a backing plate under it? again not sure though :doh:
I am going to make some hatches there, so I can install a backing plate, but I'm not sure that it is necesary. The bottom is made of 2 layers of 10mm plywood, so the first layer is the backing plate. And on top it will be the chair.
I'll think about it anyway, thanks for pointing it.
Again I'm also not sure about it, maybe some other opinions will be shared 8)
Edit: I'm also not understanding your answer I think, you laminated 2x 10 mm for the hull panels?

Hi all. Well, I'm back after a prolonged break.
I hope i'll resume the construction in a couple of days.
I want to build a d5 at the same time.

A double bottom is very rare in my designs but here it made sense: flat or almost flat panel. It is still fiberglassed on the two sides. Bottom only and staggered seams.

I had a problem on that build, since the very beginning.
My stringers slipped one side, when the boat was bottom up. I've checked the alignment several times, so I don't know how this happened.
Anyway, the tip of the stringer on starboard is not touching the chine panel, there is a 1/2 inch distance, and of course, on port side it goes out by the same distance.
I had to trim the now unmatching frames, in order to fit it straight.
That worked well, untill I put the hull panels.
They are ok, but the starboard panel didn't bent like the other, it has a slightly lower camber. It is only observed at the gunwales.

So, I built an offset rubrail, thicker in the middle, to compensate that, and after dry fitting the decks it looks fine.

I hope that a 1/2 misalignement on a 20 ft boat is not such a catastrophic mistake, because I can't undo anything.

I'm kind of sad, because I did try my best, and I wasn't in a hurry, no deadline, so I did everything by the book, except for that.
But I have to go on, it is not a structure issue or something like that.

The only thing is that now I can't rely on the plans. I will cut the pieces by the plan, and adjust them to fit, I think is the best thing to do.

1/2" is not going to make a difference in performance or strength. Don't worry.

Hi. I can't post pictures, i don't know why. It sais something about checking file dimension and correct url. I finished the top panels, the rubrail, the sprayrail, the decks and coaming.

I am ready to flip, wich was my main concern since the beginning, so i appreciate any advice.

If I find the time, I"ll do it later but I am typing this from my phone with a bad connection.
