Greetings All: Well, I'm officially Enriched Air Nitrox certified, woohoo! However, the process wasn't without a great deal of agony..... We went to the dive boat yesterday. It's a new group that the dive shop I go to for my training is using. Its boat is a LOT smaller than the previous dive op, but the divemaster on board and captain both were friendly as could be, and both seemed very knowledgeable. Well, the captain told us that he expected the seas to be about 2', with 100' vis at the bottom, with btm temps at 80degrees. NICE! Well, we get out there, and dear lord I thought I was going to die. That little boat was being tossed to and fro like I've never seen, and the seas were 6' easy, not the relatively calm 2' I was expecting. Me and another guy had our heads over the side of the boat most of the time, and everyone else was nauseous eating crackers like no tomorrow to keep their stomach's somewhat settled. I felt bad, as 3 of the divers on board were there for their open water check out dives. This was the first time for them in the ocean.... I made my first dive down (got to see a 9' hammer head, ok, so that might have made it all worth while) with no problems. Got back on the boat, which was NOT an easy task, threw up some, and made my 2nd dive. Got back on the boat again, which again was NOT an easy task, threw up some more, got back to shore, threw up some more there, and then got home, where I threw up then went to bed. One of the new open water divers got her leg slammed pretty good while trying to get back on board (definitely will leave a pretty bruise I'm sure), one of them had to board with his fins still on because he couldn't hold onto the ladder long enough to take them off. None of the new open waters managed to complete their safety stop, and I had a heck of a time maintaining 15', as it was definitely "choppy" at that depth, and there was no line dropped to hang onto for support...... NOT fun! Had I been told the seas were 6'+, I wouldn't have gotten on that boat, even though I did drive 3 hours to get there. Anyway, my question is this, how rough is too rough to do a dive like this? I understand that the answer will very from person to person, but I'm wondering what your personal cut-offs are?
