This is a story about the physics of sea breezes. Yeah, I know...the last thing you want is a physics lesson. But take it from me — someone whose grade point average was ruined by Calculus — knowing which way to go in a sea breeze doesn’t require high math. You just need to understand four different scenarios. And maybe keep a few crib notes in your pocket.

Setting out on your first cruise can be a dream adventure if you follow a few simple steps.
