Many Hinckleys and Morris cruising boats in that size range with davits? Really? Well, that's not been my observation...
If the listings on Yachtworld are any guide, dinghy davits on such boats would appear to be far from common. Of the 46 Hinckleys between 35 and 43 feet listed, only ONE 43 sports davits... Of all the Morris cruisers up to 48 feet listed, NONE features davits... Same with the 6 Bristol 38.8s currently listed, so I think it's fair to say that this is not the type of boat that one typically sees equipped with davits...
Hey, I'm just asking Graham the question, is all... I have no idea how he plans to use his boat, what sort of dinghy he's using, and so on... I simply happen to think the utility of dinghy davits on boats of that size might be somewhat overrated, but that's just me... I certainly don't fel they rise to the level of being a "safety device". The Bristol 38.8 has one of the largest expanses of foredeck and coachroof of any boat in her size range, and will easily accommodate a tender brought aboard, which with a 2:1 spinnaker halyard or similar, isn't all that much more work than securing a dink on davits... He's gonna want to do that when sailing, or motoring, in much of anything beyond flat water, anyway...
If Graham really feels the need for davits, then of course he should go for it... I'd simply suggest that before he commits to doing so, he might try configuring a temporary setup to hoist his tender, and judge the way it looks, the effect it might have on the trim of the boat, and so on... Perhaps he's already done so, and is comfortable with all that... I'm simply suggesting, with a boat as beautiful as his, that he gives the aesthetics and effect of it all some serious consideration...
Don't take my word for it, take Maine Sail's:
