Don’t forget lots of Insurance, a dry suit being that you’re in Alaska, a crew (if you are going to run it as a charter - e.g. dive leader, deck hand etc. and a USCG 6 pack/50-ton/100-ton captain’s license) oh yeah and a dive buddy. I would be happy to come up and fill that role. BTW being a displaced Alaskan myself and knowing how much you have already invested, just take a trip down south and get your certification man...take a few weeks get some good dives in and a few specialties then go back up. Lots of good dive centers in California and Arizona (believe it or not).
Oh yeah did anyone mention Beer and Rum?
