Sadly I don't have the foggiest idea... I have only played within the constraints the builder left for the owners I have never tried to define them. My guess is that if you start out by matching the...

I would go with rod, and if they really want a spare shroud (though for 4 years it's a little silly) then add a dux shroud in a bad somewhere as a get home replacement option.

I haven't, and kind of suspect it can't be done while retaining the line strength. But a custom tapered line isn't a bad idea. They do it a lot of OD race boats, and it doesn't add much to the cost....

What a crap day, sorry it happened.

The only way I know to check the chainplates would be to remove them and visually inspect them. You might be able to get away with drilling a hole in whatever...

G5's UTS is 160 ksi vs 90ksi for 316 stainless so yes you can reduce size somewhat. The tricky bit is that it still needs to match the rigging hardware so you have to retain a large enough size to...

To start with synthetics typically start out around double the strength of steel wire in order to control creep. So you loose 25% of the strength and still have rigging that is 175% stronger than the...

I would recommend titanium instead of bronze or stainless. Do it one right and never think about them again. Plus you can fill the slot between the hull and chainplates with epoxy to permanently seal...

I would second a serious look at synthetics. Saving a huge % of the weight of the rigging while increasing the strength is always a good thing.

Allene,

Wow what a dumb mistake. I was looking at the sizing chart for minimum diameter bails for eye splice load not the D/d chart. Thanks for the correction.

Actually modern high tech stuff is less prone to bending issues than older lines. Dyneema has been shown to retain full breaking strength at 1:1 bend:size.

I went ahead and upgraded the 30mm to a 40mm block which has helped a lot. The biggest question now is how long of a pennant I can leave of the smaller line.

The goal is to always grasp the larger...

Brion,

So you would just use the whipping to smooth the transition?

The major issue is that the line has to be able to run through a Harken 40 fiddle so the line is already right at the maximum...

So your recommendation would be to just run the 3mm as a core inside the Salsa? It would be a much cleaner installation so I am intrigued, but I'm not sure how it would work.

Generally the recommendation is to use a clutch where the line is in the upper range of the size... So a 6-10mm clutch works best with 10mm line. With really highly loaded lines like...
