Be careful on the light fuel load. When we go out, all we get usually is a center of lightering area location, & the ship may or may not be there. I've seen them 60 nm off - they were off a whole degree on longitude. 10 or more miles is not at all unusual, & at least down here in the Gulf there may be 8 or 10 VLCC's in the area, all lightering, & you have to find the one you're looking for in the herd. An extra half hour (better an hour) of fuel is warranted.
And the decks may be large, but the obstacles are many. Look out.
