The Round Turn and Two Half Hitches is named by Steel in 1794. If a spar is small, a round turn is preferable to a single turn. It makes a stronger knot and dissipates the wear.
One taut-line hitch is tied 15–30 cm from the aircraft and adjusted for tension, then a second taut-line hitch is tied 5–20 cm further from the aircraft and finished with a half-hitch. Wind-induced lift tends to pull the knot tighter, gust-induced oscillations tend to damp-out, and once the half hitch is undone, pushing the lower working ...
