Rig Tuning and Web Pins: The Evolution
2¢ added to the turnbuckle discussion...
The Web Pin option fits perfectly with how we sail & race this Olson34. Each spring the mast is stepped, plumbed for in-column true, with a Loos Gauge confirming shroud tension on upper and lower shrouds* are equal, which we call 'Base Line Numbers', which are kept under lock and key (not really, but kinda).
From this point forward, throughout the season, we'll spend @ 30-minutes before each race to retune the rig, either from 'stiff' to 'soft', depending upon the predicted conditions for that day. There's small whiteboard by the Nav station that lists what the rig tension is, mostly so it's not left to the whim of accurate memory. For Distance Races, especially Long Distance marathons, we tend to err on the stiff side, as we're not allowed to retune once we start.
The Web Pins make this retuning procedure far easier and eliminates the presence of 'snaggers' at the turnbuckles that are never good.
*the diagonal intermediates are tested with a hand tug at the dock, with just a bit of tension deemed to be 'good enough' (i.e. - loose), so that the offwind side while under sail is very slack, inducing a bit of belly to the main. At least that's been the thinking...
