Calm winds and a following sea my friend. Be safe and remember, you have to go out, but you don't have to come in.
i guess i look at that a bit different, chris. you don't have to go out (bad weather, etc) but once you are out there, you do have to come in.
in any case, the point here is that the lord protect you and take care of you, as this is a dangerous occupation. i do enjoy the rewards at the end, though.
