I dive with Island Divers Hawaii, they pick up from the Wakkiki hotels and bring you to Hawaii Kai shopping center where their 2nd shop and dive boat is docked. If you want to shore dive, check out www.shorediving.com. The north shore is undiveable since the high surf is here now. IDH dives the south shore and also have special trips. Morning dives deep & shallow leaves dock at 8AM, afternoon dives shaallow & shallow leaves at 12:30PM. Their boat is named the Sea Fox and will take up to 18 divers. They are the best operations that I have experienced for the last 10 yrs of coming to the island of Oahu. Good luck, Charlie
