For anyone thinking about DUX synthetic rigging, if you haven't already done so, check out the past post by Jack Molan. He has compiled a VAST amount of information on the subject, and is currently subjecting himself to his own medicine. He cruises on his "all synthetic" Searunner
34 in the Sea of Cortez
I consider him and Colligo Marine
authorities on the subject.
Regarding the cost of deadeyes... I have 40 years of experience at fabricating both boats and all of their parts
. I could NEVER make deadeyes (of any material), as neat, well made, strong, and long lived, as those offered by Colligo Marine
... AT THEIR COST! They are set up for it, I am not. In small volume, the "setup" is most of the cost.
They are expensive, but if your time is worth anything at all, they are a good deal. I had Colligo make up my runners, and have been impressed by both Dux rigging and their terminators. For my application, I was quite pleased.
One observation so far... Over an 80 degree temperature range, synthetic doesn't expand and contract
with the mast
, so tune will change with temperature. On a really cold morning, my runners are considerably looser. With wire rigging, this isn't the case. Presumably, it is that the wire AND mast
both being of metal, make them expand and contract
If one tunes the rig in warm seasons, and also sails
in warm seasons, this should not be an issue.
