In the tropics, Caribe and Avon are pretty good.
Zodiac is about the worst just like every other PVC dinghy.
If you do more than paddle between boat and the shore, get a RIB, davits etc. It is your car, pleasure craft and it's garage. We do expeditions up rivers where no man has gone before or
anchor for diving and snorkeling on reefs far from the big boat. You want very good
gear in that case, incl. a big
anchor and a waterproof bag with
GPS, handheld
VHF and personal EPIRB. I don't see it work with less than 15hp
outboard in that case.
