Building Notes

  • Dacron is used for the Trailing Edge and double dacron near the Standoffs. No Leechline.
  • A Kitehouse-style nose is used for the STD/COMP (not for the UL). The Spine pocket is sewn closed 3 cm from the top of the nose like this:Krijn_raffle_p3_39

Ultralight

The ultralight version of the NKOTB is different compared to the STD/COMP versions. The connector positions make for a slightly different overall silhouette. The Bridle is also different. Use the sail template of the STD/COMP.
