For a very simple, inexpensive “Go Fast” addition to your boat, try the auto trap. No fussing with complicated triangles on your mast to support the big kite, just two rings and a bit of spectra. Pics below explain it all.
The pic below is the ring assembly. Left of the picture is the top of the mast. The blue is the spin halyard. The left most pink string is the ring from the top. And then the two bow lines on the right go off to the trap lines.
Picture two is the actual measurement. Measuring from the very tippy top of the mast
Picture three is the measurement for where the line from the ring meshes with the trap lines. Once again, measuring from the very top of the mast.
