...And that ain't good.

Anyone know what to do about it? I put the teflon shims in, I scraped the trailing edge with scissors (as per On the Wire).

This hum is loud and I can feel it slowing the boat. Yesterday, my GPS clocked the hum starting above 8-9 mph. And it didn't stop if I went faster (even up to 18.5 mph top speed yesterday. Yahoo!) But you know, as a Hobie sailor, you always want a little bit more...

So, please, advice, comment, tips, fokelore...

Eternal thanks,
