But you can hang the boats from davits two ways:
1) on some vessels the boats was suspended from the davits and then lashed against the griping spar by diagonal cross-over straps- in the model- glue the boat to the spar and simulate the davit falls with sprue or PE
( illustrated in the link below )

2) or... insert fine wire-..tungsten or similar into the boat. make a small hook shape at the upper end.
glue and it hangs...
or make a jig to support boat, and use butt glue joint as below in my Wien

sorry Moomoon!
