Method of whaleboat davit attachment outside of bulwark

[jablackwell]

All, I am posting this topic here as well as in my build log for the Kate Cory:

 

A question all:  

 

The Kate Cory has a port-side fore whaleboat. As with all the whaleboats, there are two davits to hoist the boat up and out of the water or to lower it down. The stern davit for this whaleboat is inboard of the bulwark, like all the rest. The forward davit for this whaleboat is on the outside of the bulwark, actually in a location intermingled with the forward shrouds and between chainplates. I am ok with the location. What is not clear to me from the plans or instructions is the method by which this davit is attached to the outer hull of the ship. Ideas anyone? Images? I would imagine not only does it have to be attached firmly but also maybe to swivel? Maybe not? Maybe it's rigid? All help on this one greatly appreciated.

 

Thanks,
