A group and I dove in the Gulf during Huricane Gustaf a few years ago. The morning reports stated "some chop" so we decided to go out. It was a bit rough going out. We did our first dive and the viz on the wreck was so bad, I didn’t even know we were on a wreck. I saw metal, but I had no idea it was an actual boat. The water all that rough down below, but the viz was churned up. When we surfaced, the water was so bad, there were major issues getting back aboard. I clibmed on and the DM stayed in the water. He helped get people to the ladder and I helped them get up the ladder. It was the worst conditions we had seen on a dive trip and it took major effort on everyone’s part to get back on the boat. Of course, after all that, the Capt cancelled the the second dive and went back into port. He refunded 100% of our money for the day and was very apologetic for even taking us out in it.
