    Don Grillo has been teaching us to do precisely that, right wing tied lower!  :>)

    The Proper tie down knots withstood 70mph force winds for me when I was based in Florida

    On the subject of one wing down, with the 2-33 tail on a stand there would be all of the weight on one side of the fuselage rather than balanced equally. I’m not a fan of that.

    Steve,  having a wing slightly lower (right wing in our
    case) keeps the mostly westerly winds from getting underneath the
    wing and lifting it. You would not want to have an excessive
    amount of wing down as you mention below.

    As in all groups, Sky Soaring being no different, there will be a small handful of those who can do such things as making a proper knot to secure aircraft. However to protect the clubs aircraft it is necessary to accommodate the lowest common denominator, those who are “knot” capable of making one. I suggest staying with tie-downs that require a minimum level of expertise. Even a cheap Harbor Freight strap will protect better than just one improperly tied knot. All it take is just one loose rope and once again another glider will be lost and destroyed.

    I also think the probability of aircraft damage would be higher by having a wing lower on the 2-33s. It is a good idea on other gliders.

    This may be a bit late, and if you use knots and it’s been successful I’m happy to hear it. That said I sail and keep my boat moored on Lake Geneva. I’m sure some boat owners use knots, but I don’t know of any. I use thimble and eye splices. Knots lower the breaking strength of the line they are in (up to 50%) and can come undone. Splices minimally reduce the strength of a line and if done correctly can’t come undone. We have a lot invested in our sailplanes and our tie down equipment should be sized for length and strength for each sailplane. I’m willing to help with this if help is needed when I’m back in town.

    Hi John,

    I would be interested in meeting with you to learn more about the thimble and eye splices. It sounds like something to consider. Greg Tomczyk

    Greg and any others. I use thimble and eye splices but I don’t make them myself. I use braided line and the splices are more than I wish to tackle so I buy pre-spliced line. In the boating industry there are many “generally used sizes” of mooring pendants and I easily find one for my use. That said,  I saw Mark Mallamo giving instruction on making eye splices this last summer in dyneema or spectra line. There are instructions on line for most all types of line. Finally the only difference real between “eye splices” and “thimble splices” is that the thimble splice is an eye splice that is made small and tight enough to hold a metal “thimble” in it. The thimble allows the use of steel connectors with a “soft” line. I am not advocating the use of line over straps, just using something made for and strong enough for our intended use. John Lincoln

    Someone contacted me on where I used to get the webbing used for the tow ring straps. Any 1″ climbing rated webbing will do. It’s been a while but I think it was at REI.
