Tom,
I'm based in Knokke-Heist (VVW Heist). I don't know where you live but I'm certainly interested in taking you for a sail if you want to.
What I can tell for sure is that you will sail as fast on the F16 as you did on the F18.
I'm sure it would be more interesting for Cirrus to built an F16 compliant model instead of their 16 foot boat they have now.
Next year I'm planning to sail the regatta at Carnac. And I hope some other F16 sailors will be there too, to get France interested.
Regards,
Gill
