Status Report:

I purchased some "Board Carpet" from Annopolis Performance Sailing for 1.85/ft. It's 1" wide 1/4" thick with adhesive backing. I only needed about 1" to 2" per side to tighten up the daggerboard play.
This reduced the hum by maybe 60% of what it was.
It's almost tolerable now.

However, I'll probably end up smoothing the trailing edges of both boards and rudders in the fall.

I also tightend up my tiller extension a bit which also helped the helm response.

Question:
On starboard tack I'm getting slight weather helm (good) but on port tack I'm getting a little leeward helm. I noticed that my port tiller arm has been dented inward from the inboard side by maybe 1/4". Could this be the reason for the leeward helm on port tack?

Thanks,

Tim
