Also want to piggyback on what’s been said regarding seasickness prevention IF you are prone to it:
1). AVOID being on your phone. Similar concept to reading in the car
2). Don’t go down in enclosed spaces
3). Avoid being the one who has to get a hook out of the net or untangle a gigantic tangled mess of fishing lines. I’ve noticed a period of intense concentration on something close up on a wavy day can trigger feeling nauseous.
