For sale is a brand new, never used 8' Sport-Brella that was intended for a boat I sold soon after. These retail for $65, I'm asking for $30 plus the cost of shipping. I also have a Clavey Paddlesports umbrella mount that I'm selling as well, if you're interested. It's not a perfect fit for the umbrella, it requires some modification.

Here's a description:
  • 8-foot umbrella canopy features UPF 50+ sun and weather protection for the beach, camping, sporting events, concerts and festivals
  • Oversized umbrella provides privacy and maximum protection from the sun’s rays and rain with two patented side panels; stow-away clips store the flaps when not in use
  • A heavy-duty 1.25-inch center pole has a built-in tilt mechanism for adjustability; zippered windows allow for airflow and prevent the umbrella from blowing away
  • The oversized auger bit with an integrated twist handle easily and securely anchors the umbrella in sand, grass, and dirt; included stakes offer extra security
  • Internal pockets store a phone, snacks, or other gear; carry bag, stakes, and guy lines are included; packed umbrella measures 53x3.5x3.5 inches and weighs 8 pounds
