By private vessel or bareboat you can do it on the ROAM App on your smartphone. The boat needs a customs decal.
Last week we had one of Captain Jays/ CYOA 45 Mono's out and used the ROAM App passing Johnson Reef. At Stevens the App still indicated "Processing". We changed our course and grabbed a Ball at Lind Point, reported to C&I and while we were waiting our turn it Indicated "Accepted". Lesson learned, Sometimes the app's on Island Time :-)
