Depending on the experience, age, and maturity level (I've been around some 50 yr olds that need a good switching) of those actually involved in the diving and operation of the dive boat would determine whether or not I would want to assume the liability of such an outing. Also does your FATHER EXPECT a professional with insurance and experience because if something goes sour it most likely will be him saying "Hey you helped him plan this and we gave you a free ride out and paid you x dollars to ease our minds and look he got bent" or worse! He will be the one calling the lawyer. Unfortunately we live in a society where we as divers are supposed to know and assume the risk. Our families, however, are not under any obligation it seems based on past occurences. Especially if the person we are escorting, buddying up with, or helping plan something like diving where there is a genuine risk of serious injury is a minor not related to us. The poster did not specify his age and I'm not saying he is a minor, but the disrespectful "rich old geezer" remark when speaking about one's father is not something you normally hear come from a responsible young man over 18. If my son were to refer to me in this way I'd be on the boat and he'd be scrubbing the dock on his hands and knees. Sorry it's just this generations lack of courtesy and respect for those who provide for them and indulge their every whim with out expecting anything in return burns me up.But that's to be expected from some of them who cannot even pull their pants up or put a proper size shirt on, or the right size hat on straight. Back to the topic at hand. If I'm going to assume responsibility for any action I may take as a diver whether it's in the water or out or whatever action I am assumed to be taking as a guide, buddy, source of info, I want everyone to be crystal clear on what the exact relationship is, before I step on that vessel, accept any form of compensation including air or gas, and know what my responsibilities are or what you think they are. I also would expect the boat operator to be able to provide adequate service to a diver in the water including making it safe to get in and out, being there when we come up (involves keeping track of those below), and mooring in such a way that it does not destroy the coral reef. Which may involve going down and setting the anchor (possibly another expectation and which may also require a seasoned diver who knows what they are doing and can assume responsibility if something goes wrong with this.) To me it seems all the more reason to go with a seasoned, established operator. Which I am not but really would like to be someday. Jim, PADI Master Scuba Diver and Divemaster Candidate
