(I wish I had) laminated chines & shears with more-but-thinner strips

Am I alone in my long-term concerns?

Looking back, I'm thinking I would have wound up with a stronger, longer-lasting, wave-pounding-tolerant boat had my chines & shears been constructed with a greater number of thinner laminations. I constructed them with three pieces of 1/2" thick white oak, epoxied together. None of them enjoyed being bent to the bow shape, and every time I hit a big wave, I wonder if things are about to snap. I'm sure I'd have a stronger boat if I had built in layers making laminated shears / chines with something like twelve pieces of 1/8" thick white oak.

I also think that tite-bond III *might* have been a better choice of glue than epoxy for putting the chines / shears together. After all, if my chines & shears are immersed in water, that's called "sinking", and I have bigger problems to contend with! :)

For sure, my next boat will be made with a more "lamination" approach.

Or am I completely over-thinking this?

Your over thinking this.

If the chines didn't break when you bent them, you're good to go.

you need to get away from white oak,
it is grossly over-rated

The hull plywood is what makes these boats strong more so than the framing. I crossed a wakeboat wake at 3/4 throttle last time I was out. The hull smacked and slammed HARD. I've done this many times. Inspecting the framing after a few outings there is zero change in any of the joints. You built your boat from tried and tested plans with proven methods. It's not going to fall apart.
