My husband and I are considering doing a liveaboard in the Red Sea in May or June of this year. He has a problem with one knee that results in his having a weak kick. He can dive in minimal currents such as Bonaire, and he can, of course, drift. He cannot swim across a significant current. We prefer shallower dives so as to have longer bottom time, but can go deeper as needed. We would love to see larger sea life if possible. The liveaboards listings offer a choice of north, south, or combination. Taking his problems with swimming across currents in mind, do you think that a Red Sea liveaboard is a good plan for us? If so, what sites would you say to go to and what sites should he avoid due to current? We obviously don't want to do a liveaboard where he has to sit out most of the sites.
