Hi George, I have lost count of the amount of money I have spent looking for a perfect dinghy. I have had aluminium dinghys, a timber dinghy, a firbeglass 'suicide' pram dinghy, an injection moulded, double walled plastic dinghy, a soft bottom inflatable and now have a 10' RIB Avon.
Each one has had its advantages and each its disadvantages. I think as the cruising fraternity graduates to marinas rather than swinging on the hook, requirements for dinghies have changed. I think you probably have the mix about perfect with two dinghies, each one suitable to a different purpose.
I agree with your choice to stow the dinghies inboard. I think stern mounted davits are potentially the most dangerous appliances on board an offshore cruising boat.
In my perfect cruising world, I would want a 2 metre, noiseless, 6 man hovercraft as my dinghy.
Methinks it is easier to find the perfect woman, than it is to find the perfect dinghy.
