Thanks Brian,
Thought they looked familiar.
I work at Austal Ships and was on the Armidale Project from the start, also the Cape Class, which use Vestdavit equipment as well, a very good product. Talking to the Reps who come over to commission their gear, the Davits on the Armidales are their most used system in terms of number of launches/recoveries per week/month/year. Bearing in mind that they also supply equipment to many Navies, including the USN for the Nimitz Class Carriers!
The Armidale davits are rated to 4.5t, and the Capes 6.5t.
