The 76 would have to be one of the best helicopters for landing on moving decks. Most companies seem to use 10 degrees roll as max but if the occasion warrants it, this should not be taken to be an out & out max figure. I have seen a roll of 15 degrees with 25 degrees pitch up & 12 degrees pitch down with about 90 feet of swell, that figure came from the pressure alt, so it could have been higher. The nose wheel extended quite a bit on the pitch up but nevertheless the 76 sat very solidly. The deck had a rope net & the 76 did not slide at all. I don't think another machine could have handled those conditions as well as the 76. Obviously it was not easy for the pax to climb aboard, in fact they crawled in to avoid the blades. It was that or drown when the rig sank 30 minutes later.
