Keep your keel on your boat where it belongs!
If it's high tide and you are about to pass in front of the American Yacht Club while following the channel upriver, you may be tempted to turn toward the club house and shoot across the open water and into the AYC mooring area only a short distance away. DON'T! Lurking a few yards to the south of green can C-17 are the aptly named Halftide Rocks, which are quite an obvious hazard about three hours after high tide. These rocks have claimed more than their fair share of fiberglass, wood, lead, and propellers - not to mention whole boats. Be especially careful at night since the channel here is quite narrow.
Your Best Approaches
Depending on tide, here are the best methods to use in avoiding the hazard when approaching the club or mooring field
When you are heading upriver, be aware that the riverís current on an ebb tide (current downstream against you) can run very fast, so it is advisable to run past green can C-17 for some distance before attempting the port turn toward the clubhouse. Even then, you should crab against the current by keeping your bow pointed to the right of the club. With a flood tide (current upstream with you), it is safe to turn soon after passing C-17. Unless you know the area, it is also not advisable to cross behind the rocks into the eastern end of the mooring area; it does shoal in places.
