Hello Mart
After racing an I-17 It should be easier racing with crew.
I,ve raced both I-20 and 17 singlehanded and the only real difference is size and small variations in the set up .
Every crew OR TEAM does things a little differently .
Most all I 20s crews set and snuff the spin and most play the spin sheet line though in light wind some skippers play it .
It takes practise to work as a team and it is a good idea to switch places and communicate well.
Locally there is a large active fleet of I-17s --you may find some usefull info on the CRAM site .
One thing I would like to see is development of a class standard lightweight high speed winch system in the loop for raising and lowering the kite . The loop COULD eliminate most slack in the line and that would eliminate the kite from ever dipping into the water.
{just my 2 cents}
I cut off most of the extra line though some lead it to the back crossbeam so the skipper can help with the sets .
Hope that is helpfull .
best regards
