16 nautical miles
Mean tidal range of 4.07 feet at Bristol Ferry. Floods north, ebbs south. For ideal timing, launch from Weaver Cove a few hours before high tide, rounding the northern tip of the island around slack and having current assist while heading back.
Tidal Information
The channel between the launch and Prudence Island is a popular route for powerboaters and a high-speed ferry. When current turns against wind, the area can get fairly rough.
