In my experience, face grain strips are flimsy, tend to warp easily, and split when bent very much, as compared to quarter sawn strips.
I see you have quite an investment so far, and it would be expensive to start over again.
I've read that others have built boats with face grain strips, and have been happy with their finished product.
Me, if all I had was a wet noodle to build a boat, I'd try my best to do it.
So my answer is GO FOR IT !!
Uniform strips, are the best ! If they vary in thickness, your bead and cove will be off center.
A way to resolve this, is to mark the face of the your strips before you bead and cove them. ALWAYS keep the marked side either up or down, when you run your strips through the router.
Example: Lets say you keep all of your face marked strips, face marked down while routing.
When you go to strip your hull, keep the marked faces of the strips, next to the forms.
This will leave the inside of your hull the most uniform, making it the easiest to sand and scrape. You will appreciate this later !!!
One last tip. And it's a big one ! When you bead and cove your strips, run them BETWEEN your fence and router bit !
This will make your strips uniform in height. If your strips are 5/8"-3/4" high, set the gap between your router bit and fence at 5/8". They will all be the same.
I apologize for the crudeness of my router set up, but it has put out uniform strips for well over 25 boats. I would however take donations for improving my set up ! HA !Just kidding !
Best of luck !
