Ideally I'd like to have a sail that would allow me to paddle and sail at the same time; especially in light winds. The now unavailable Spirit Sails look like they would have worked well for that purpose.
Some years ago I had the opportunity to try several of the downwind sail rigs in a head-to-head tripping test, including the QuiverSail, Pacific Action Sail, Windpaddle and Spirit Sail. For my solo boat tripping purposes the Spirit Sail was by far the best.
Small, light, compact, easy to install on the fly in the boat, no mast sticking up or battens lying retracted across the hull when the sail was down, carbon fiber battens that flex to spill sudden wind gusts for a smoother ride with fewer “Oh-shit” moments.

Not a bad point. I was thinking of ways to rig a DIY sail to be hands free but if my hands are going to be holding the control lines of a factory sail then I shouldn't expect the DIY version to be hands free. Hands-on would make it a lot simpler.
Hands free if I don’t have a rudder is pretty important to me. I can plant a paddle blade as a rudder, or even as a small leeboard if needed. I can still paddle in light winds, or even power stroke on the downwind side for real speed. But more than any of that, when the boat gets moving and riding waves I really want to have a paddle in my hands. Even in a ruddered boat under good control I often hold a paddle, maybe just as a comfort item.
You can go hands free using sheets/lines, fairleads and cam cleats, but setting up and running the lines on the fly is a mess at best.
Making something DIY similar to the plug-and-play Spirit Sail is not only doable, most of the parts are readily available.
The Spirit Sail consists of three parts. The sail itself is simply the sail material, held in a V between foldable shock-corded carbon fiber battens. So, sail material, carbon fiber tubes that sleeve together, shock cord kit. Simple.
The base mount for the sail is a (was) simply a rebadged Scotty Rod deck mount. $8
http://topkayaker.com/index.php?main_pa ... ts_id=1030That Scotty deck mount has a toothy arrangement in the center so that a rod holder (or etc) can be locked in place at 0, 30 or 60 degrees.
The missing and unavailable piece of a Spirit Sail is the Y connector that fits into that toothy base, so that the sail can be locked at 0, 30 or 60 degrees. That Y connector is no more; not a single Spirit Sail vendor I have found has one left. BTW, that piece, in the Spirit Sail design, does not float. Ask me how I know. Hence maybe why there are zero spares still in stock.
Scotty however does make a couple of accessories that fit in that base mount with the same 0, 30, 60 degree lock function.
The swivel fish finder post bracket and the universal sounder mount.

Some articles that may be of interest, also from Tom’s Top kayaker site.

Some dimensions if you decide to try making a hands free DIY sail. Spirit Sails came in two sizes, full size (17 SF) and mid-sized (8.5 SF).
The full size uses 6 ft battens, with two shock corded pole sections on each batten. It is a handful in any wind to get up or down, with lots of sail flailing around, and having the extra batten section on each pole to take apart and fold (while holding the first folded sections together) is awkward at best.
I just took a full sized SS out and unfurled it. Unfurling it was fine, but even standing at the windless shop bench it took me a couple of tries to get it properly folded, furled and put away. And that was with the sail battens already detached from the base and held in hand.
The other issue with the full sized Spirit Sail is that, for me, it is often too much sail. In double digit winds the 6 foot tall battens will flex so much that it can be difficult to remove the battens from the Y to collapse the sail.
In a 15-20 mph tailwind I’ve had the battens bent towards the bow at a held-steady 45 degree angle, with so much stress on the connector that I couldn’t rotate it to dump air and the following waves were big enough that I couldn’t afford to put the boat sideways, even briefly, to spill air from the sail.
All I could do was ride it out until a shallow sandy beach appeared where I could safely ground the boat. The second time I did that (yes, twice) I began to appreciate the force of the wind filling 6 foot carbon battens bent near horizontal. Nuh uh.
I still bring the full size and put it up in light winds, but I know to take it down before the breeze hits the teens.
The mid-sized SS uses 4 ½ foot battens with one shock-corded sleeve on each side. WAYYYY much easier to step and unfurl. With a little practice it takes me 10 seconds to set up or take down the sail, maybe 15 seconds if it is really windy. I can, and do, use the smaller sail in higher winds (10 mph provides a decent cruising speed, 15 is fun fast, 20 starts getting exciting) and have never had a problem turning the mount to spill wind and detach the sail.
I know you are a tricky devil Alan. I am sure you could DIY a hands free sail of your own design using a few manufactured pieces. $40 or $50 in parts and pieces for a small, lightweight piece of gear that can provide effortless propulsion? A good paddle can easily run quadruple that, and a small sail is a whole different arrow in the quiver.
