A while back I was able to link to a video showing how to right a Scot whose centerboard had slid back into the trunk.  The video showed the use of a rescue boat with a line tied to the low side shroud plate.  I had the chance to put that info to good use this past weekend in 25 knot winds  It worked like a champ!
I tried to find that video on the FSSA  site to review.  I could not find the link.  I think it was VERY helpful as we would have been stuck without the knowledge. Others may find it useful as well.
