I am in a family of 5 who is trying to plan a liveaboard trip. My mom, myself, and my sister all dive and my youngest brother will be in the next year. My father;however, went through all the class work and pool sessions but couldn't do it when he got to open water. Since he is the one who is working and supporting the family we don't like to plan vacations around things that he doesn't enjoy or participate in. We talked about doing a liveaboard trip with him and maybe having him give it another try in open water and get the cert. He said he would be up for it but only if there would be something to fall back on if he didn't want to do the diving. He really enjoys sailing and said he would be all for a trip where he might be able to learn about sailing and help out the crew sailing a catamaran or whatever sailing liveaboard there may be. My question is, are there any liveaboards out there that will let their passengers help out with the sailing or maybe have the crew instruct them in how to sail the boat?
