Chas,
I made a model of Bardic Ferry back in the 70s.
I assume you are using the Vic Smeed plans and I agree that the fine detail of the crane mounting isn't altogether clear. I made mine as best I could from the plans using styrene strip.
There was a model of the vssel in the Midhurst show last year, photo below. The crane is a bit out of focus but may help.
The best photo I have seen of the ship which shows the crane is this one on sister ship Ionic Ferry:

Bardic Ferry's crane can also be seen in this photo:
