I'm looking at a new dinghy as well, and thinking about a murcury RIB.
the ABs are huggely expensive, as are the caribe which I have now.
also most are rated for 10 hp and I have a 15 hp. mercury is reasonably
priced at defender and is rated for 15 hp (the 310 model). not to heavy
at 130 lbs in hapalon. I have not met anyone yet who is happy with the
aluminum bottom.
