A-5 Corp with its 45' slip is located in Honokohau Harbor in Kona Hawaii. You can do fishing, diving, snorkeling and whale watching with your commercial/charter permit. The night time manta snorkels or dives will soon be restricted to grandfathered in permits..But no body knows when the restrictions will start. Would need to contact DLNR/BOR about that. At moment there is no restrictions on the manta snorkel.. Maximum size boat would be 45'5" allowed in the charter permitted slip.
