I'm looking to upgrade my backstay adjuster to allow for more raking of the mast heading downwind and for more bend in the mast heading upwind. I'd like to put in a 12:1 purchase system...I'm wondering if anyone knows how many pounds of pressure is exert

Sounds like a question for Catalina's technical assistance department, i.e., Jerry (sp?) Douglas. If you leave him a voice mail(and maybe now they're using e-mail) he's very good about getting back to people.

Doug - maybe I'm missing out on something but my only question is "why?". I have the simplest adjuster possible - two sheaves connected by an O-ring across the backstay, with a lanyard to pull it down. The tension on the 2 stays keeps it in place and to

Derek,

I have the same type adjuster on "Life o' Riley" now...I am looking for far more adjustability (is this a word?). I would like to have the ability to pretty much let off the entire backstay and use the rear shrouds to rake the mast forward head

Jeff - with all due respect, a Mumm is a pure racing machine. Our C25's are racer/cruisers and we have to accept their limitations. You are comparing apples & oranges!
If your main is blown out there is only one good solution - buy a new one! A 12 - 1 ba

To add to Derek's comments, what you probably need is a new mast (which I assume will put you out of the class). Even the newer racer/cruisers have fractional rigs with tapered masts that, pound per foot, are much lighter extrusions meant to be bent. Ou

Thanks for the input fellas - Steve, Derek, Dave

A 12:1 could very well get me in trouble...I'll probably go with the 8:1 configuration offered by Catalina Direct (although I'll probably throw my own together from West Marine parts and with the help of

Can anyone explain why you go faster downwind with the mast raked forward? Does it have to do with jib shape?

Thanks.

Doug - to reiterate, why bother spending that money? If you go to the old home page, somewhere you will find an article titled "Fleet 2 Speed Tips" Read, mark, learn and inwardly digest! It has been my bible for the last few years and it is accurate and

Premature posting...I hate when that happens. What I meant to say...

I do appreciate your advice. The whole reason I am interested in exploring the adjustable backstay with more travel is due to some information from Jeff Pierce's Racing Tips section

Doug - it would seem to be a good idea. However, I don't know how loose you carry your backstay & forestay. I have about 8 - 10" sag in the forestay and the backstay will wave about a foot with the adjuster off. I can pull down on the lanyard until the 2
