Hiking Lines


I've seen photos of people racing in their Flying Scot where the crew had a line wrapped around their feet or had their feet underneath a line to enable them to hike out further.  Is this class legal?  If so, what is the best way to set this up?

Here's the information that should be helpful.
The link to the current FS Class Rules. See pg 35 for specific info, It states the following: 


4. No hiking straps, flying trapezes or other contrivances which achieve the same purpose may be used. Up to two (2) hand lines affixed to the centerboard cap are permitted, providing: their ends are terminated in a whipping, back splice or knot (not a loop); and, their ends cannot extend beyond the rub-rails when fully extended with the ends touching the deck.
