This video gives the viewer the true sense that, once you get out on the sliding seat, there's nothing static about sailing these craft.
Couple of things to point out;
- The dangly rope led to the outboard end of the sliding seat is the jib sheet. It allows the jib to be adjusted while you're hiking at the end of the seat.
- The German owner hikes the IC the same way I used to hike, wrapping my ankles and shins around the bottom edge of the sliding seat. Most IC sailors don't do that, they hike off a hiking strap that spans the middle of the seat from one end to the other.
- He's got a very funky mainsheet arrangement. Most mainsheets just attach to the back end of the seat carriage with a cleat on the back or the forward beam of the seat carriage.
