Hi all,
I'm trying to understand the new rigging rules. Specifically, I was wondering if it is legal to simply upgrade the common pre-2000 8:1 vang rigging by 1) replacing the 2:1 cascade loop with a block, and 2) adding a sheave running on the Holt key-block "becket" pin (or shackling a separate block from the pin)?
I'm certain that 1) is OK, but 2) seems to be in a grey area. Have there been any clarifications by the ILCA about this kind of modification?
I actually rigged one of the club Lasers here at the UW using a shackled-on block for 2), and there appears to be enough space for that approach to work (I needed a more powerful vang to help some lightweight students on a windy day). I was planning to take a photograph, but things got hectic at the end of the lessons and I forgot...
Cheers,
