Better to not try at all. The east channel above Strong Is. is very narrow and best located and logged at lower tides. The narrows to Little Bay, however has many big rocks along Sipson Island and the narrowest part has shoals to starboard and rocks to port. Turning back to Strong Island, the northeast corner of the island has one marked rock but many more extending twice that distance from shore. The course to find Crooked channel from this direction is best found on a calm day and well logged.
Little Bay is mostly grass flats with the channel circling the western shore.
At the northerly head of Little Bay, Namequoit Point bar extends far to the east. Follow the Buoys around the bar here and you won't run into trouble. Caution should be taken not to discover the rocks lining the edges of these rivers. Keep to the channel center. Throughout the Pleasant Bay system, there are flats and shoals.
