You need to become more experienced before taking a bunch of fellow rookies abalone diving under the guise of being an expert (I'm of course referring to your side business at Hunt n Gather SF).
First, it sounds as if you went diving on a particularly rough day. If the wind is whipping spray in your face as the sun comes up, you should rethink your plan, maybe go get coffee or something instead. Second, use a FLOATLINE to mark abalone! A bunch of newbies are going to stab countless abalone in their efforts to pry them from the rock, and without a floatline to mark their spot, they'll drift off of it between breath-holds, and leave the ab to die as they go off in search of another. If you know what you're doing you can easily pry an ab off after it has clamped down onto the rock. Just measure it, mark it, and come back to it. And finally, an abalone is NOT a filter feeder! Do you tell your "clients" that? They are grazers. Big difference.
Seriously, someone of your experience level is in no way qualified to lead diving tours. I'd hate to hear of someone getting hurt on your watch.
