Other Navigators

Names and locations would be welcome if you recognise any of these.

Funnily enough I get the feeling that this is Milford Beach or close by. That could be Motutapu in the background. I do know there is a sloop rigged Navigator around these parts but I have only seen it on the marina unrigged.
Anybody recognise the location?
Just when you thought you would never see the sloop rig. Resonable guess that this was taken at Lake Rotoiti Classical boat regatta.
