A cracking sail this weekend in a good five building towards a six, quite rough sea state (sea breeze). Little Swift was flying at over 8 knots.. (I didn't even think this was possible!). Crew said they saw 9 kn on the gps but I'm not that sure so not logged that!.

I kept getting a buzzing/vibration through the boat at that speed which I thought must be the keel vibrating in the case?It didn't cause me any consternation, more I felt she was singing along happily blasting about!

Has any other owners experienced this ?
