Lake Poinsett is a 3,300-acre natural glacial lake in Hamlin County in eastern South Dakota — the largest natural lake in South Dakota and the centerpiece of the Glacial Lakes region that defines the northeastern South Dakota boating landscape. The lake sits in the Coteau des Prairies — the elevated glacial plateau that separates the James River valley from the Minnesota River valley — surrounded by the productive agricultural land and wetland complexes of eastern South Dakota’s prairie pothole region. Lake Poinsett’s natural basin and prairie shoreline support a walleye, northern pike, yellow perch, and bass fishery managed by the South Dakota Game Fish and Parks. The lake is the flagship of the Glacial Lakes State Park system and draws boaters from across eastern South Dakota and western Minnesota throughout the open water season.

Upholstery FAQ
Costs vary by boat size: Single seats typically run $200–$500, while a full pontoon reupholstery generally ranges from $2,500 to $6,000. For a 25ft+ cabin cruiser or ski boat with complex curves and piping, expect to pay $5,000 to $12,000 for a showroom-quality finish.
If the vinyl is brittle or “chalky” from the sun, a patch is only a temporary fix. For boats over 5 years old, a professional shop will typically replace the entire panel to ensure the new material matches the structural integrity of the rest of the seat.
These are signs of microbiological staining (mold/bacteria) growing from inside the foam. While surface cleaners help, permanent removal often requires a professional deep-clean or replacing the underlying foam and treating the vinyl with an anti-microbial barrier.
Marine-grade vinyl (28oz or higher) treated with UV and mildew inhibitors is the industry standard. However, Sunbrella fabrics are increasingly popular for cabin interiors and biminis because they breathe better and stay significantly cooler in the direct July sun.
Most factory stitching uses polyester thread that breaks down after 3–5 years of UV exposure. Premium shops use PTFE (Teflon) thread, which is virtually immune to sun and chemical damage and often outlasts the vinyl itself.
