Do you race bouys with them here in FL? I have never seen one on the course, so I don't know if they race with spinnakers or not. Are they on snuffers, "manual", or roller-furled?

Great on light air distance racing (Mug comes to mind), but judging from the jib-only finish at Hogsbreath, they are a handful over 15 kts. But then again, what boat isnt?
