Thank you for the welcome, Gary

The reason for most H16s sailing w/o spins is probably that spins aren't allowed in their one-design class. As far as I know, they are only "legal" for youth events (<=21 years).
After going out on the water with the spin, downwind-sailing became a whole new experience! Before spin, that course was peace and quiet; with spin, screaming speed, high-frequency weight trim, bows in the water! It felt great, especially after being back on shore in one piece.
I feel I already profit from your experiences posted here, so thank you all for that.
Best regards,
H77
