The paper trail on 8 Boathouse Road is short, and the shortness is the story. The year on file is 1955, no sale appears in the record since, and the brokerage calls this the first time the property has ever been offered. What comes to market is a six-cottage summer colony on a flat 1.16-acre parcel in Shinnecock Hills: five cottages of two bedrooms and one bath in roughly 800 square feet apiece, a sixth of one bedroom, knotty pine and checkerboard linoleum throughout. At the road, a hand-lettered green and white sign still reads Jo-B-An Cottages, Summer Rentals, and carries a 631 phone number, an area code that did not exist before 1999. The colony was taking bookings into this century. Great Peconic Bay lies a quarter mile off, the town boat launch around the corner, and the parcel holds R-20 zoning. It comes to market whole.
