Bonded, really? The ones I've seen where big stainless brackets bolted to the aft cabin superstructure above the upper rubbing strake - with suitable reinforcement behind i'm sure.
If it wasn't a straight swap job its probably not worth it alright.
Not chemically bonded, I used the word as a generic term for how the davits are joined to the boat.
They are bolted to big stainless steel brackets that are glassed into reinforced pads.
