Many of the charters only go out on the weekends (certainly the case with North of Nago). Of course the military will have July 4th off so you shouldn't have a problem - just make sure you reserve plenty in advance. As far as diving the Emmons, you will certainly need a rental car to get up north. Ishigaki is great - did two days of diving there (5 days) but only saw mantas on one dive - kinda hit and miss during the summer. Keep your fingers crossed.Oh tentative dive plan
July 4-6ths go out with Destiny Charters (thinking Kermas and Maeda Point), though I am trying to get a day to go out to the Emmons with North of Nago.
July 9-11 go out with Prime Scuba Ishigaki.
