During last years sea trails, I played around with a traveler for the forward portion of the mainsheet. I am finalizing the design and installation now. I want to use 1/4 amsteel (pictured) . The Sheave that the traveler runs on is designed for 1/4" material but I believe that 7 mm Dynex Dux will also work. Colligo Marine's website shows 7 mm Dux fails at 15,000 pounds - unbelievable.
This line will see some pretty high loading - especially during jibes. Keep in mind that my mainsheet is "split" fore and aft with 4 parts
just ahead of the pilot house and another 3 parts
at the very aft end of the boom (and boat). The boom is a bit small in diameter for its length and is a flexible. I believe that the aft portion is going to see higher shock loads than the forward portion in spite of it having one fewer mechanical advantage "parts".
My hope is to be able to quickly remove (without tools) the traveler line in order to stow and reduce sunlight degradation.

Pic #2,3. Close up of traveler anchor
point. I will create end "eyes" with those Chinese finger puzzle type splices - whipped for security
. Eyes will be just
large enough to fit over (with determination) the cross toggle to prevent unintended releases during flogging (boom is really long and heavy so it does not actually flog).
Pic #4. Aft portion of mainsheet. I wanted to keep the aft bench/seat clutter free and simple so a fixed sheet anchor
was chosen. Initially, I tried a plain block and used the bollard pins below to belay. This proved difficult to use at times when under load. The problem occurred when on a tack that caused the sheet to cross over the belay making it difficult to remove. This cam cleat block is the most sophisticated part of Panope's rig. It has proven to be very handy under sail.
I am thinking that a proper rigging
job should utilize Colligo's line terminators with a shackle. My hope (as always) is to use simple homemade stuff. Also, (as mentioned above) I would prefer tool free removal
of the traveler.
I have very little experience with synthetic rigging
so any input would be greatly appreciated.
