Davits on a normal sized cruising boat are great for coastal waters and island-hopping. If you are not a superyacht or a Big cat, you wouldn't want to use them offshore. Hard dinghies are great. If you find one that fits on your deck because of the size or because it is a two pieces dinghy, buy it. If you decide for a Rib, don't make the same mistake I did: Buy a hypalon inflatable. The sun destroyed my first 3 inflatables within 2 years. Then I bought a Caribe 8 in Hypalon and after 7 years it is still on deck inflated under the tropical sun: it is very stable to carry second anchors of 45lb, the weight is in the right place of the boat when crossing, and it is also our liferaft, ready for launching. But if you have the space on deck, take a 9 or 10 ft.
