vibration

[D. Fox]

OK, I gotta ask - what's the vibration I sometimes feel in the hull in a stiff breeze?  Was out this weekend, and sometimes I'd feel this short-freq. vibration run through the boat for maybe 1-2 secs at a time.  What causes that?  Thanks,

Dan

The vibration is very likely the standing rigging transmitting the vibration from the sails.  Check the rigging for proper tension and remember that the aft lowers should not be tight.
