"Departure - if there's a nice drop-off, it will probably be tempting to nose over and head off like a diving seagull - don't do this unless you're absolutely sure there's no wires to spoil your fun. Otherwise a normal departure or a level-ish airspeed over altitude type one would be good"
If it's an elevated pad (like a toadstool), may I suggest that you don't just move forward from a five foot hover. If the engine were to fail just as you clear the deck, your tailboom hitting the pad would cause you to head nose first into the drink. Better to go up vertically to about fifteen feet or so and then move into forward flight -an 'offshore' take-off.
