If its dead calm and 5 knots when you leave, you'll be OK.
You find that the wind comes in early out wider so it just means a lumpy ride back in but tomorrow you shouldnt have any issues with that. Worried about being seasick? Just take some kwells and life is good. Unless i know 100% that someone doesnt get sick i recomend kwells just to be sure because its no fun when soneone is sick.
Light winds all day so it'll be heaps better than being at work

if its really calm it might be glassed off but i've never caught fish when its like that.
How big's the boat, what are you chasing and how far west of west end are you going?
