The limits are somewhat flexible, but realistic, and enforced. As for USCG SAR, it is somewhat depressing. They will eventually get there, I think, but they are slow. They do have hoists in their cute little Dolphin helicopters. ;-) They don't have a lot of range, but they can refuel on any of the fuel platforms, and often do. My only real complaint is that it seems to take them a rather long time to get started.
