actually we frequently will opt not to go out if weather is not good. Once we see 4-5 foot seas or a very strong chop, it is just not safe to put divers in the water. The boat can handle it but a boatload of seasick divers, or divers falling, or having issues getting up the ladder are not worth the money. We had questionable weather a couple of weeks ago, started out but as soon as we broke the inlet, we turned around (choppy with occasional 6 foot seas). no argument from customers, they liked our safety approach and, of course, we comped their next trip.
