Roger, I think you're accurately ID'ing some of the problems with moving to davits on your smaller boat. Conceptually, the basic problem with this choice is that the system you want to add - davits, dink, panels
and perhaps more before it's over - are all fairly independent of boat size. IOW you could have a Bristol 35.5 or 38.8 or even 41 and yet all the add-on's would likely be roughly the same size and same weight. OTOH their impact on your smaller boat will be more detrimental.
I think one issue we all become somewhat experientially oblivious to is the impact of all this stuff on windage, primarily because we incrementally add all this 'stuff' and incrementally suffer from its effect on the boat. As one example, let's imagine making anchor
choices for your boat as it came from the factory; you could be reasonably assured that you wouldn't have to load up the bow with beefy anchors, chain & windlass
and yet hold well in a tough anchorage. But now let's add the normal liveaboard
assortment of 'stuff', then add the canvas
'stuff' (no doubt including a bimini), perhaps add some extra pieces like a radar
array, whisker pole and jug farm, and now add the davits/hoisted dink/solar panels
. When we think about it a bit, it's easy to imagine that the challenge of staying anchored has measurably changed and so we build up that "anchoring" side of the equation to compensate. Of course, this just adds to the negative side of another equation, which is how the boat handles (in comfined harbor basins, sailing in light winds, heavy weather
handling) and on it goes.
I don't think this impeaches the idea of davits...but it's another step down the road of asking a boat to perform like a boat while making it more and more into an RV. For protected waters, probably not a big issue. Long term and with longer runs in mind, that might not be true. Obviously, in the end that's your call.
