Different types of
davits offer different compromises. Different combinations of davits and dinghys offer different compromises. Davits of any kind is a compromise in itself, as are all other means of storing a
dinghy or not having one at all, as are different styles of yachts and sizes. It boils down to personal preference.
Me personally, there are a lot of things I dislike about davits. Springing the bough off a
dock, going stern in, having a
dinghy in the way of entering/exiting, the extra length (and sometime extra harbour fees), windage, boat balance, the worry of it suddenly heibg filled with
water (or sliwly if the drain plugs), its looks, drilling into the boat, costs...
I also enjoy not having a dinghy on
deck. I also enjoy the ease of which I can get the dinghy in snd out of the water with the
engine,
fuel tank, my groceries, etc - many days in a row. I enjoy not having to tow (noise, loss of speed, in the way at
anchorages, getting the tow line to jam my rudder - which btw happened to me when I was a total noob). I enjoy not gaving it tied to the side at
anchor or in a marina (knocking about, in the way, easy to steal, getting griny...). I find lifting the dinghy and
engine on and off the mothership a PITA when I have to do it often.
If heading
offshore for some time, then I prefer to have the dinghy on
deck or in a locker.
Ofcourse I did not imply swapping between a
wind vane and davits out at sea. The suggestion was more in terms of before leaving the Canary Islands to cross the atlantic, and then sgain when you get to a port on the other side of the pond a few weeks later. That much said, I think that most
ARC type boats could enjoy both davits and a
wind vane without having to swap back and forth.
As for making a strong enough construction to hold even a fairly heavy 10ft
rib with a 20hp engine with console snd
fuel, and also have the dinghy well seated so it doesn't move arround at sea (add some bits and bobs to the floats so it nests on the davits) - many have done it. However much I like a
RIB though, something light and stowable is the better compromise for me.
I
sold my
Jeanneau Rush 111 (aka sun shine 36) as there were too many issues with it that would be impossible or too costly to rectify. I'm trying to test out as many boats as I can - trying to settle on what I want within my
budget (still undecided). Some I have rented so to get to test them better. One thing is certain, after having tried one with davits - I'm never going back. Most of the time I enjoy both sailing and
living aboard the floting condo type production cruisers - more than a long keeled heavy
displacement dungeon of cruiser with kegged rudder and constrained living space both below and in the
cockpit. My main concern however is all the bad stuff I have heard about failing steering on these production boats - hence my
research into
wind vanes as a backup.
Your points on the importance of balancing the boat is a very good one. I am convinced that it is more than lijely a significant contributing factor to many steering failures, and in the ARC in particular. I am under the assumption that ARC attracts less experienced sailors (like myself) - people who might not only be able to fully assess the condition of their steering system and rudder, nor be properly able to sail or steer the boat with the TLC it needs to endure the crossing - a combination that can easily spell disaster.
