As part of my son's birthday/high school graduation present I said I would take him on a liveaboard. Since I've done an Aggressor before and he knows others who have been on various Aggressors he wants to do an Aggressor either in Kona or the Caribbean. He's not new to boats having not too long ago spent a week on the Shedd Aquarium's research boat in the Bahamas. He is however a new diver, they did snorkeling off the Shedd boat, so he's comfortable being in and under the water but the diving should be for a newer diver. Any suggestions? Thanks.
