Turbo fin question

I installed my new turbo fins last night. I noticed the brass adjusters on them. Can somebody explain what these do exactly and which way adjusts what? I assume they have something to with the pitch of the fins? IDK The paper that came with them says nothing about them and I am brand new to all this Hobie stuff. Thanks again in advance.

In a nut shell, they are for custom tuning. Tight = fast with more resistance, loose = easier to pedal but slightly slower. I've kind of played with them a bit and not noticed any significant difference, so I set them in the middle but made sure they had pretty equal tension.

Awesome, thank you! Thats what I did, set them in the middle.

Nice to meet you yesterday.

Check out the hobie forums.  One of the members tested the turbos at different settings against his gps for speed.  If I remember correctly he found that loose was the way to gain maximum speed.

Loose provides more torque, do faster acceleration.  IIRC, top speed was the same on the tests, but look it up to verify.

Per Lees comments above, here is a good Hobie forum link on the subject....http://www.hobiecat.com/forums/viewtopic.php?f=11&t=10176&start=0

You found it, that's the post I was referring to.

On a re-read he does conclude loose is faster in a sprint (only 2%) and less effort at cruise.

Wherever you end up setting them, make sure it isn't too tight.  The nut will actually pull through the hole which could cause your fin to fall off.

There's probably only one way you could know this for certain... Hopefully it wasn't too far from shore.
