Shipyard Park sits right at the harbor's elbow, where ships were once built and where the town now carries lawn chairs down on summer evenings. Lawntain keeps the grass in that part of Mattapoisett and well beyond it looking level and lived-in: weekly mowing, trimming, clean edging along beds and drives, cleanups in spring and fall. Salt wind off the harbor is hard on turf, so consistency does more good here than any single ambitious afternoon. The result worth chasing is a lawn that looks unfussed and still entirely kept. Cut, edged, blown clear, and gone before the light drops behind the masts.
