Newburyport, Massachusetts Chart

Newburyport is located on the southern bank of the Merrimack River, 3 miles from the inlet. The town is roughly 45 nautical miles north of Boston and 58 nautical miles south of Portland, Maine. Known by locals as “The Bar”, the Merrimack River inlet has a strong current (up to 4 knots), and can be very dangerous, especially when a strong ebb tide opposes an easterly wind. Novice boaters routinely get into trouble here. Heavy boat traffic during the summer only exacerbates the situation. Coast Guard Station Merrimack River monitors the river entrance and will provide current inlet conditions via inquiries on VHF 16. Note too that a flashing white light at the bend of the north jetty signals that conditions are favorable for breaking surf.

To enter the river from the north or south, head for lighted red-white buoy “MR” and proceed to lighted buoy R “2” off the north jetty. The best advice is to transit at the top of the flood tide. Locals favor the northern side of the channel to avoid the shoal that extends off the tip of Plum Island.

Once clear of the inlet, the river channel has a mean low water depth of 12 feet (6 feet above Gillis/Rte. 1 Bridge). Be sure to keep buoy R “8” to starboard after clearing the inlet to avoid Badgers Rocks. The shallow Joppa Flats are visible to port, followed by the American Yacht Club, the Coast Guard station and Newburyport’s downtown area.

Be sure to follow the channel markers closely as you approach Newburyport, as you’ll need to steer clear of Half Tide Rocks off buoy GC “17”. This can be a tricky spot to navigate in a strong current with heavy boat traffic. If you wish to continue upriver past Newburyport, note that the Gillis/Rte. 1 Bridge has a vertical clearance of 35 feet at low tide. It can be raised by hailing the bridge tender on VHF 13 or 16. Mean low water depth is 6 feet west of the bridge.

Note: there is a strictly enforced no-wake zone from R “8” Fl R 4s to G C “11”.
