I'm always trying to reduce rigging time by finding more efficient ways, I'm hoping some of the wing sailors here have discovered a better way for the SX wings.

The "book way" is to use clevis pins/rings in two sizes for the eight locations where they are needed, four on the main beam connections and four on the small strut pieces at the rear of the wings.

I'm using eight bolts/nuts rather than ring-dings as it seems more secure, cheaper, hate ring-dings, and bolts don't have anything to snag.

The bolts probably don't take any longer than pins to install but do require several tools to put them all in, I use a nut driver, pliers, and screwdriver, which I have to keep track of.

I had thought of using toggle pins like these
http://www.amazon.com/dp/…000BYCHP/ref=cm_sw_su_dp

But they can be a problem when put through a pipe because if the toggle-flap goes sideways inside the pipe it can be impossible to get them out.

But something like that, tethered to the wings or boat would be ideal, no tools, nothing to lose, just insert and go. Any magical fasteners I've missed?

I know exactly what you are talking about. As a kid I used on to hold up the telescoping section of a birdhouse pole. I use to place a wrap of scotch tape around it to make sure it remained aligned, til pushed through to the other side. Once it came through, you just turned the lock tab down.
That would probably be a bit of a pain, as you would have to tape them before insertion & removal.
What about those clevis pins with the safety spring? They can be had in many length/diameters, round, square.

This one is specifically for pipe.

That actually might be a good application for those hairpin type fasteners. There are a number of types of locking hairpins that are more secure. Like these: http://www.pivotpins.com/catalog/bow_tie.shtml or these http://www.pivotpins.com/catalog/RueRing.shtml

This look promising, have to check what sizes it's available and if it comes in stainless. Do these things spring closed to that position or does the wire clip onto the pin?

that bowtie pin has possibilities, have to see one in person, I don't want any exposed stuff to snag a foot or line.

Some great suggestions!

I know they come in stainless, & 1/4" for sure. Don't know what lengths are available or what you need. The couple I got years ago, (not for a boating application)were just spring loaded. They held bett than one might think, as the round clip sort of grips the pipe.

Check a local farm/ranch supply store. I picked up the clevis pin with a safety spring there. They aren't stainless but I am in fresh water, and mine look almost new 4 years later. They are cheap and if they rust in a couple years easy to just replace. I also use a larger one for my trailer hitch pin. Got the idea from Fleet 2 in California, which is full of H18M's, and they all use them.

Lots of cool things you can find in a ranch supply store. I found shoulder length disposable gloves (you don't want to know why they have them, if you don't already) for doing fiberglass work inside my hull. Kept my arms clean of resin while working through a small port opening.

Here is a link to Grainger for something like I use. A wopping $2.75 each.

Grainger (Acklands Grainger here) is a GREAT source for supplies. They have lots of stainless fasteners including clevis pins, detent pins and pop rivets at a fraction of the cost you pay at the sailing shop!
