Glad to hear you enjoyed it. It's amazing how easy to sail the 87 is.
I find it interesting that you found the 32 fin too small and I found it slightly too big. Probably down to the strong tide you faced. I'm only a couple of kgs lighter.
Now you have a GPS I hope to see your tracks on http://www.gps-speedsurfing.com/gps.asp
. It's really easy to post on there.
