The company now does business world wide, but is still family owned and based in Halifax.
On Friday, July 26 I noted a newer model of Rosborough's "Roughwater" [TM] series operated by Canadian Border Services. While the cabin looked familiar, the bow was much shorter, and the collar did not extend the full length of the rigid hull. There is no boat that looks like this on on Rosborough's web site: http://www.rosboroughboats.com/
The unnamed and unnumbered boat was giving close escort to Queen Mary 2. (Note the "Azipod" symbol on the big ship's side - also the large blotches of scaled steel.)
Rosborough also builds conventional looking craft such as the survey boat pictured earlier this year doing a bottom profile survey at the Fairview Cove containment basin.
