I used to be an expert, 30+ years mechanical engineer, designed all sorts of bending/cantilevered things.

IMHO, UHMW is way less stiff vs. oak/oak laminate. That means the boat will likely flex/work more for a given load.

Data: UHMW, E (modulus of elasticity) 110,000 psi
Oak, E, about 10x that above.

And yeah, I've made all kinds of stuff out of both. Stay with oak. UHMW is amazing stuff, but it is not structural grade material, not for my boat!
