DUXBURY BEACH FYI – GW 100 yards offshore front beach, 200 yards NORTH of 1st crossover. 9:45am 9/5/2022. Fin sticking up out of water three feet for about a minute, moving south, parallel to shore. Could NOT see the outline shadow of a GW so can not rule out common Mola. Keep an eye out. – Capt. Dave
