Noles is right @ the beginning of the flair

No as far as I know no other damage, thankfully I was alone at sea so no one got hurt, thanks for the concern. 8)

No buttblock is still in place

It's difficult to see in the picture but it looks like the glass, outside skin, did not break. That means the side flexed and the faring and paint cracked. In that case, it is easy to repair but I am still surprised. It is very stiff there with that wide gunwale.
It must have been a major wave.
I have been in that area only once but I remember strong currents and wind against current can create a very steep sea.

Tell us more.
Boy your good :) that's more or less exactly how it happened, imo went into the wave correctly but for some reason got me and smashed me hard into the water, I'm not sure if the glass did break all the way, I think there are some strings broken. Crack stops at the rub rail obviously. Don't forget I did reduce the width of the gunwale from 10" to 8" maybe if I stayed with the design this would not had happen, I don't know :doh: Yeah at the moment (hurricane season) we have strong currents and wind or no wind at all yesterday it was the first. :wink:

Hope the following pics help some more

The slightly narrower gunwale is not the reason.
The boat is extremely strong up to 6" above the sole but in an open cockpit boat, those topsides are never as strong as in a cabin boat. Thicker walls would still bend. The only way to make it stronger, that means able to resist that kind of slamming, is with very wide and tightly spaced framing.
The top of the gunwale is the flange of your beam. The horizontal part is where the strength comes from but right there, you have a seam in that flange! Just at the end of the flare. That seams worked like a hinge and that is how the side bent.

You must have pushed your boat much further than what most people would do Or the, you were caught in a very unusual situation like a wave braking just at the wrong time.

It should not be difficult to fix working from the inside. Build up glass, add a frame is you want.

I'm sorry Peter. I was just trying to ease the pain of what was obviously a traumatic event with a little humor. I know how much time and effort you put into building a very nice looking & tough boat. I won't post in your threads any more.

Are you kidding? why won't you? your remark didn't bother me at all! I really think it isn't a big deal to repair, but I wasn't sure, that's why the head scratching smiley, please post anything you want 8)

Edit: I knew when I put her in the water she would get damaged, never had the intention to thread her like porcelain , I tried to make her nice but she has to work and hard! That's why I'm planning to take her out of the water once a year for big maintenance like anti fauling and so on

Okay understood.

Although I indeed do push her quite a bit, I don't think I do it in a irresponsible way, and I do think she can handle a lot off stress but this was a strange situation indeed, at least for me it was.

Not sure what you mean by adding a frame, if it is a frame like frame F I don't feel much for that, especially because I think this was a situation what wouldn't recur often

That frame is not necessary, it was just a suggestion. More glass under the crack from inside should do the job.

okay thanks, and then just fill the crack on the upper side with fairing compound? what glass should I use under there?

It would take a lot of fairing to add glass outside. I would add 2 layers of biaxial 12 oz. inside just in case the core suffered and finish the outside with fairing compound and touch up paint.
The inside between the frames, above sole to gunwale, where you can reach. maybe add an extra layer of tape to the longitudinal stiffener. I don't remember your building blog but you have that longitudinal half PVC pipe there, correct?

Okay again thx easy fix like that 8) , Yes that's correct half pvc is filleted in and double taped, but that part doesn't have any (visible) damage and feels like a tank.

Wow. Must have been one heck of an impact. Are there butt blocks on the backside there? If so, I wonder if fiberglass splices would have retained enough flex to give and take. I could see how a butt block could lead to a hinging open of the joint in an extreme flex situation. I think I'd be tempted to put at least a light cloth over the repair. I'd be afraid there would be cosmetic cracking/crazing there over the log term without.
