|The vang puts high loads on hardware attached to the aft face of a mast. This can cause failure as diaristson and I discovered during a recent regatta. To avoid a repeat of this problem at the CMBA Nationals I decided to see if I could teach myself how to splice eyes into the ends of 4 mm twelve strand spectra line, sometimes called "spectwelve". A spectra mesh strop, looped around the mas,t is SOP for the high ratio vangs on Europe dinghies. Borrowing this strategy would permit us to transfer the loads from the vang to the front face of the mast rather than to a fairlead attached to the aft face. An eye splice in spectwelve is similar to Chinese finger cuffs--the harder the pull, the harder the splice sets. To keep the line from creeping up the front side of the mast I first fabricated and epoxied a small carbon cloth/G-10 fairlead to the front of the mast similar to the one John Z. taught us to make on an earlier post. The only differences being that my fairlead has a hole large enough to pass the line through and John's craftsmanship is streets ahead of mine.|
You may have to copy/paste the URL for the video. For some reason youtube wouldn't transfer it to this post. Bottom line: the strop I made stood up to the two days of racing in the 10-15 knot winds we encountered at this year's National Regatta at Elizabeth City last weekend. In higher winds I suspect something else in the vang cascade will fail before these eye splices do.
