As the owner/operator of our Oahu dive boat, we limit our group sizes to no more than 6 on-board. It’s a unique dive boat in Honolulu because of this. Most boats bring out group sizes 20 – 30 on-board. Why dive with a Honolulu scuba company that doesn’t own a boat or uses a cattle-maran jammed full of 30 divers? Small size groups equate to increased safety and greater fun.
