Its fine for day cruising but when the yacht gets pooped you most likely can say goodbye to your tender, not to mention possible damage to the contraption bolted to the stern.
We learned the quick way to store a tender on deck is a better idea then having it on davits when heading offshore, as you never know what the sea can dish out...

In fairness, this may not be a problem in all cases. I carried my previous large dinghy in davits in all kinds of weather (and I mean ALL kinds, including a knockdown in the North Sea), and never came close to being pooped. Given enough buoyancy at the stern of the mother ship, and high enough davits, and this may not be a problem.


But as has been said, all that mass swinging around in a seaway is a different question, and the windage is unacceptable for a keen sailor, at least, if you sail much to weather.




Note that we have been talking about monohulls. I think on a cat all this may be entirely different. First of all, no heeling, so different load dynamics altogether on the davits. Second, a dinghy in davits on a cat will be in the wind shadow of the house, so probably the windage is not noticeable.

Re: Windage implications of dinghys, davits, and arches

i have seen the results of being pooped for a boat exactly like mine with bent over davits and gone dinghy.
now i am planning on installing a combo davit, boom gallows and solar/kayak mount and traveller for mizzen which i use for sailing, using taller davits--the sea wolf had davits low to water, as do ct 41, yet below level of working mizzenboom.
i use no r i b but a walker bay rigid 10 f t dink. is impossible for me to lift n stow that by myself , so i caved to davits.

Re: Windage implications of dinghys, davits, and arches

On my 36 ft cat we have a walker bay 10 on the davits. Ensured there was a quality good fitting cover on the dinghy to try and deter the water ingress. Not been an issue so far.
I think, as been stated previously, davits and cats are good together.
