Sjælland Rundt 1988

 Back in 1988 I participated in Sjælland Rundt in a boat just like Cool Blue... It was Diva, Bianca 107 DEN 34, owned by Ted Gräslund. 

There's actually six Bianca 107s on that list. One did not start, so five participating 107s.  The Bianca 111 had even more participants.

I actually found the results online. Here's a cutout:

 Apparently, there's nothing you can't find online. What fun!
