just picked up a 272LE but not sure I have all the components to rig the main sheet. There currently are only two Gehauer blocks on the bottom of the boom although there are three or four (one at the aft end of the boom) attachment points ... and a double block on the traveller ... and there are two Shaffer blocks permanently fixed to the mast below the boom. and another Gehauer block on the deck that leads to the cockpit. Ideally we would do a "W" to the traveller ... lead it to the mast at the boom and then down the mast, across the deck ... but it doesn't look that is the way it wants to go. I would need more Gehaurer blocks to make this logical. Second problem is that it looks like the way to attach the bottom of the gib to the roller F. is to use rope and not a fitting ... maybe i am just too used to a harken.
