Has anyone with a M17 with a CDI furler toyed with installing a backstay tensioner? I have my backstay tightened down as far as the turnbuckle will allow but notice that the headstay/furler looks a little limp. To compensate I tightened up the headstay but now I have very little rake, if any. I've seen recommended rakes as much a 12". I'm thinking that a backstay tensisoner might kill two birds with the same stone..... tighten the forestay and create some rake??? I'm thinking of using a pincher design using a 4 part purchase to tension a pair of blocks to ride down the split stays. Has anyone tried this? Are the attachements at the the deck for the split backstay strong enough to handle a backstay tensioner? Am I toying with danger that might damage any of the rest of the rigging?? Any advice is always welcome. Thanks, Joe M17 Seafrog #651
