Boy that hurts!
Last time I dove with them the weather was not that good at the dock but we went out, It was very very wet all the way out.
I got down and did my thing (baged a few nice Blacks and headed back to the line). By the time I got out on the surface the seas were 4' + and just as I was on my last step I got hit with the mother of all waves from the back. Well.. I landed up on the deck and 6' from where I was just a minute before (speargun on one hand, fish bad on the other and there was blood and bleading fish all over the spectators. What a mess that was.
I soon found that most of the divers on that trip were beginers and most did not got in at all, only two got in the water and one lost the way to the boat, panic, dumped and was seen floating away from the boat at a good clip in high seas.
I din't know but someone was throwing life jackets in the water as to keep the same drift as the diver on the surface. By the time we pulled her out she was in bad shape but got better by the time we pulled in.
The point of the story..You just never know who you're diving with and when the weather is bad they should not get out.
