Fin-keeled boats like the Tanzer 22 typically sail at anchor, because they lack the mass and directional stability provided by a deep, full keel.
This is a large advantage when sailing, but not so much so at anchor. The anchor riding sail is flown from the backstay, and works as a windvane to keep the boat pointed into the wind. It is often sheeted to one of the toerails, although I sheet mine to the mast.
I started by cutting a triangular shape out of 9oz sailcloth. Heavy cloth is an asset here, as it minimizes fluttering of the sail in use.
Once the main area is cut to shape, patches are attached to each corner. For ease of design and construction, I used webbing loops at all three corners instead of grommets. Due to its small size, only two hanks are needed to clip it to the backstay.
Closeups of the corners of the sail. The head (photo 1) is attached to the main halyard. The tack (photo 2) is tied to the stern rail. The clew (last two photos) is sheeted to a strap on the mast.
As with most items on a boat, this sail does double duty. Before it was ever used as a sail, it served as a rain cover on our 2002 cruise of Lake Ontario!
Finally, three photos of the sail in use. It's inherently difficult to take pictures of this sail, as it's not possible to get off the boat and take a picture while it's normally in use!
