Just in passing we have several interested parties with gliders and no tow release. We were able to tow these by using self adhesive Velcro. We put one side of the Velcro on the underside of the fuselage near the nose and used a smaller strip of the opposite Velcro on the tow line. Separation is easy the tow pilot asks if the glider pilot is ready then on the count of three the tug reduces throttle and commences a descending left turn while the glider pilot makes a level right turn. The Velcro peals apart and the tow is complete. On the tow line use just enough Velcro to stay connected under tow but small enough to peal away when necessary. This is a good method for beginners as well as the tow will part easily if things go wrong.
