Personally, I prefer to have a bit extra safety margin on the highly loaded controls, like the mainsheet... if you've never seen a block disintegrate under too high a load and shoot pieces past your head... you don't know why I do this... but I'd recommend going with the 57 mm blocks..

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Here is what Harken recomends, assuming you have the loops at the bottom of your boom. If you have webbing holding the boom sheaves, then a different sheave is needed. They recomended 40's for the whole thing. I have 57's for the main, and 40's for the micro per their recomendation on the compuspec.

ZZ,

Here is a pic with the micro on it. Not sure if you have done anything as of yet.

Thanks marty. I'd like to do something like that, I bought the 40mm carbo blocks and ran some 5/16th Samson Apex single braid through it. If it actually measured 5/16th in diameter than it would run fine, but it looks closer to 3/8th, this apex stuff must run really large, and therefore drags through the cam cleat and little hoop. I'm thinking of filing the hoop/fairlead to make it a little bigger.

Or I could just buy a 1/4" mainsheet which is what the 40mm carbos claim is their max line size.

Last I checked, the 40 mm Carbo Harken blocks have a max line size of 3/8".

I have worn out a few full size parts and find they keep things pretty close to the edge

If a dirty bottom slows you down what do you think it does to your boat

If you keep that one arming up you will go blind. And for a guy who says he doesn't talk about his member you seem to be quite open about it.

zz,

I would NOT file anything, but going to a smaller diam line would be better in the end. Otherwise, "IF AND WHEN" you do go smaller in line, you cam cleats may not close on the line. I have 1/4" in my 40mm micro setup, and it works quite nicely. Not sure I would want to go bigger in all honesty.

I have 1/2 or 9/16 in the 57mm main part.

I was at a lewmar winch maintenance class at local WM the other night, and he asked if we thought we needed new winches. The rep mentioned, "most" folks that feel they new new winches, are running line that is TOO large for the sheaves they have. Take the diam of the rope, multiply by 7, and that is the sheave size you need. As I am typing this, I am also thinking I am not quite right, but in the ball park for the ratio etc. just something to think about re the 40 mm sheaves, max line would be 6mm or 1/4" lline!

Traditionally, sheaves are supposed to be eight times the diameter of the lines running in them. That has changed a bit with modern materials...some for the better, others for the worse.

The carbo fiddles will fit 3/8" line, and have a max line size of 3/8", however, the cam cleat Harken uses is only 1/4". They also reduce the SWL to 400 and something pounds b/c that's what the cam cleat can hold. The cam cleat is the weak link in the system, and the tiny fairlead doesn't help.

I wouldn't mind going to 1/4" mainsheet, but I think it would be a bit of a pain to get a grip on it. I'm using 5/16" apex and it measures closer to 3/8". The 3/8" apex I originally bought measured in at 1/2". Either they have a new guy working the rigging shop at Defender, or Apex runs REALLY big.
