Gilligan:Otter,
Mike Severns, Ed Robinson and B&B Scuba are all good 12 pack boat operators. Another one to keep in mind is a 6 pack boat run by a man named Ron of Dive & Sea Maui He is a good person to talk to if you want to charter is entire boat and call the shots as respects dive sites. I think there are only two (English speaking) 6 packs left. The other is Makena Coast Charters.
Thanks.....
