Hi Michael,

Of course, your boat, your choice.  But I'm wondering if there is a way 
to have the best of both worlds (a stronger beam and keep the looks).  
Why not reinforce even your NEW beam with Al sisters, then attach a thin 
wooden laminate over that so that the reveal is wood?

Also, the new boats don't have a wood beam there, and to my eye, the 
beam doesn't look THAT bad (on 521, it's painted to blend in with the 
overhead).

I'm wondering if the question to ask is "why did that adhesive fail?"  
Seems to me it has to have at least a LITTLE to do with the working of 
the beam as the rig compression oscillated while the boat is being sailed.
