keel fairing

I power washed 30 years of anti-foul paint along with the fairing off my lead keel today. Once I get the keel totally cleaned up I was going to put a couple of coats of interprotect on it. Other than fairing out the hull to keel joint, is there really a need to fair a lead keel?

I'm not happy unless I'm complaining about something.
I'm having a very good day!

Re: keel fairing

fairing also gives less edges for stuff to grow... but yeah, it's mostly a foil efficiency thing.

I've read that you can fair before interprotect or after, it really doesn't matter. The smoother you get the final product, the less drag it'll create. Also the better shape the overall keel has, can dramatically improve your point, and/or your sideslip. There is a pretty distinct science to getting the shape right. Depending on the boat make and model you may be able to get a keel template from a place like compu-keels to help improve the shape of your keel in the fairing process.

Oh and if a power washer took your fairing off, then it was likely time to refair anyway.

Re: keel fairing

The existing fairing was nothing more than a skim coat.
I never gave any thought to the nooks & crannies that would become habitat for stuff.

Thanks for the info Hudsonian & Shnool!
