Ron, remember that it was our choice not to address the issue for 10 years ... we didn't notice it before we left the country because it's not really obnoxious until it's shaking the entire rig in the black of night when you're trying to avoid a ship that won't answer you on the vhf! It had nothing to do with Mack not being local because they were 3 hours away for the first 3 years we had that sail.
Cheers! Jan
