The Wednesday night weigh-in at headquarters for the Martha’s Vineyard Striped Bass and Bluefish Derby appeared to follow a familiar pattern. The first fish of the night was a bluefish, followed by a striped bass, then a bonito. Then came a cooler full of blues, with a striper thrown in for good measure.

Seconds after the bell was rung at 8 a.m. Sunday announcing the start of the Martha's Vineyard Striped Bass and Bluefish Derby, two fish were carried through the door, lifted onto the scale and recorded on the leader board in the Edgartown harbor weigh-in shack.

The shack at the end of Main street in Edgartown lies dormant most of the year. During summer months it is used by the Edgartown Junior Yacht Club. During the winter, it sits empty, a little outpost on the harbor. And for five weeks in the fall, the shack comes alive.

The gray-shingled shack that sits in front of the Edgartown Yacht Club in the harbor goes unnoticed by most visitors to the Vineyard, but during the Martha’s Vineyard Striped Bass and Bluefish Derby it comes to life for four short weeks when fishermen bring their fish in for the morning and evening weigh-ins. Twice each day they come to the derby headquarters and get their fish recorded in the official database.

Fishermen participating in the 68th annual Martha’s Vineyard Striped Bass and Bluefish Derby are already out plotting a strategy for success. Nearly all of them will visit one or all of four popular fishing spots: Menemsha Jetty, Joseph Sylvia State Beach, Memorial Wharf and Metcalf’s Hole.

Put plainly, most of the movie footage is not terribly good. Some of it is out of focus or overexposed. Some of it lingers too long on fish lying dead on the rocks. Some of it wasn’t even shot on the Vineyard, and it takes a judicious eye to determine which scenes show the Island and which show Nauset, Cotuit or the jetties at the northern end of the Cape Cod Canal.
