For all of the people up north who resort to quarry diving, the first time on a dive boat is...different. Help us out. Some things you wish you would have known BEFORE your first boat dive.
Here is something to know before you sign up for a liveaboard boat trip. Hope it is related enough to be on topic.
I certified in Alaska, did my 4 dives, and then went to Australia. I had arranged to make 4 liveaboard boat trips while down there - 3 3-day trips and 1 7 day trip. What I found was that each boat had different "rules" for how the dives would be conducted. These rules included things like maximum depth, maximum length, prohibition against "reverse profiles" and such things.
On the first trip, they had a maximum 40 minute dive limit AND a 50 bar rule (back on the boat with 50 bar or more). That didn't really bother me, since I was a new diver and couldn't stay down that long anyway.
On the second boat, they just had a 50 bar rule - you're back on the boat with at least 50 bar, but no set time limit. This was reasonable.
On the third boat, there were essentially no rules. The deck was open from time A to time B. You could stay in as long as you wanted, go as deep or as shallow as you wanted, and make as many dives as you wanted. They preferred you back on the boat with 50 bar, but they didn't seem to be real concerned about it. They also allowed solo diving if you could show you were capable.
On the fourth boat, they were nazis (and I had heard about it from someone on the third boat who was just coming off having dived on my 4th boat). Based on what this person told me, I would not have made the 4th trip, but I had already paid, so there wasn't anything I could do. They were very strict about how long, how deep, reverse profiles, etc. They checked your dive computer to see if you exceeded their limits and if you did, you got banned from the next dive. I got banned from a dive for doing 0.1M beyond their maximum depth for that dive. And we're not talking about going to 40M or something. On that boat, the first dive of the day was 20M max. Each successive dive was 2M less - and if you happened to go deeper than your previous dive, even if it was less than their limit, then you were banned for the rest of the day. If you had some other violation, you were banned for the the next dive. They also had maximim time limits, and the 50 bar rule. It was rather ridiculous. Some of my times ended with a half tank or more of air.
Had I known the rules for the 4th boat BEFORE booking, I never would have booked that trip.
So, the tip I am trying to pass along here is, if at all possible, find out the dive deck rules BEFORE booking. In the case of the 4th boat here, it was ProDive Cairns (Australia). I'll never dive with them again. ProDive Airlie Beach and ProDive Townsville were MUCH more reasonable - although now the 40 minute limit would bother me. Mike Ball's 7-day trip out of Townsville was just top notch - but also very highly priced. Still, if you ever spend the money to go to Australia, it is THE trip to take.
Good luck!
