Unmanageable Mainsheet
We've encountered a bit of a problem with our new-to-us Pearson P30. When close hauled or on a close reach in any kind of air at all, we find the mainsheet basically unmanageable. Sometimes we can't even get the mainsheet out of the cam cleat and, even if we do, even I am not strong enough to trim the main in sometimes. (It's not like I'm about to win any strongman competitions, but I'm no 90 lb. weakling, either.) We find ourselves sometimes having to pinch up enough to depower the main. As you can imagine: This doesn't do good things for ones speed.

The thing that gets us is the PO used to race our boat. We're wondering how in Neptune's name they managed that mainsheet? We're wondering if we're doing something wrong, but cannot imagine what.

We're wondering if we need to upgrade something? Here's what things currently look like:

The P30 normally has the traveller in the back. The PO moved it up and upgraded it to that Harken traveller you see in the 1st and 3rd pictures. That works like a charm :).

That cam cleat has pretty aggressive teeth. Once that thing clamps on, under load, it takes two strong men and a boy to get it loose.

What do y'all think?

I think you need a bigger fiddle block arrangment and a thicker sheet.

Also to release the rope from the cleat, ypou don't pull on it, you give it a 90 whip, to relase.

I can search a good fiddle for you if you are interested and give me a few minutes.

A thick sheet helps, as does more mechanical advantage. I have triple blocks top and bottom and no worries.

Giulietta 09-21-2007 01:09 AM

Here we go...

For the boom..

For the traveler. But on this one you turn the cleat the other way around so it releases when you yank the sheet upwards, not downwards, because if you yank downwards, you keep hitting the legs of those seating near it.

Put a spring belloow the fiddle on the traveller to keep it VIAGRA!!!

By the way...the blocks you have look pretty shitty and weak, good for a smaller boat.

Giulietta 09-21-2007 01:13 AM

And you can, if you really want it to be butter smooth get this for the boom

This for the traveller...again inverting the cleat..

and VIAGRA for the block

Your blocks are indeed small - wonder if those were original ??? The PO may well have kept the nice Harken blocks for his next boat and replaced them with something he had lying around...and then again, maybe not


He may well have been using the winch to help him, as well as the boom vang. You may find that if you use the vang in concert with the mainsheet that things get a little easier...

I would buy bigger blocks - what you have looks a litte undersized.

Giulietta 09-21-2007 01:18 AM

Then if you really want to impress your lady...

Check this one out...

For the Boom: This

For the traveller,this..

Just looking at them I get an orgasm......

By the way mine are of the same series, Lewmar R1

For the traveller Lewmar is the best, for other applications Harken is the best...get the Lewmar...its very good, and then we would have something in common..but if you get the racing Harken, we will also have something in common

Look how sexy the Lewmars are..

Giulietta 09-21-2007 01:43 AM

I forgot to tell you, the two top ones are Harken, and their references are the numbers you see if you save the photos, the Lewmars have the references if you click the links.

All of them have ratchet features, that allow you to ratchet the main block sheave, so you only cleat when needed...COOOOOOL

SEMIJim 09-21-2007 01:54 AM

Wow, quick feedback. Thanks, guys! :)


Could you dig up the Harken (I assume that's what they are) part numbers for those 1st two solutions you showed? Or at least the sizes you're recommending (from which I could probably find part numbers myself)? Thanks! (Yeah, I'd really like to impress my lady, but I can't quite justify $600 for the Lewmar solution ;).)

Edit: Okay. Got it on the part numbers. Thanks!


We were wondering the same thing. This man was not shy of spending good money for good equipment. Note the Harken traveller. He also upgraded the two jib sheet winches from the original, rather small Lewmars to Harken #40's. He didn't scrimp on anything, basically. So... I dunno. I'm guessing what's on there now are the originals.


A thicker sheet? Recommendation? (Obviously I'd need bigger sheaves to accomodate a thicker sheet.)

Thanks, guys, for your help.

The Lewmar 60mm fiddle with cleat is around $165, and the fiddle for the boom, also 60mm is around $70.

The Harken fiddle is also around those prices...

Give Sailnet store a call you WILL be surprized the price is around $210 for everything you need. If you go 60mm

For your boat you don't need the 80mm the 60 mm will do fine.

And if you want to go 80mm (75 mm for Harken) its $320 all you need.
