It does not appeal as an exactly sensible idea...
I only fly a machine with emergency pop-out floats, but I cannot imagine that the utility floats were designed to use the helicopter as a watercraft for extended periods.
Plus considering the insane amount of corrosion I've seen on helicopters parked *at* the ocean (including the supposedly corrosion proofed R44 Clipper's...) I don't even want to imagine what parking them *IN* the ocean would do
