[Rhodes22-list] Centerboard thumping

[Peter Nyberg]

Peter,

I've never removed by centerboard cap, so I can't comment on the internal construction, but I can say that my centerboard will also thump when it is down and the boat is at anchor and rocking a bit.  It's done this since I bought the boat newly recycled from General Boats, so I consider it to be normal behavior, and not something to worry about.
