Joe, I worked out a simple but effective backstay tensioner which uses a split backstay car like the Johnson unit. Connected to the backstay car is a becket block/clamcleat combination sold by Duckworks ( www.duckworksbbs.com/hardware/cleats/sd002530/index.htm). On the transom, I use the eyestrap already installed (by Bob Eeg) for raising the stock rudder. Connected to this by a shackle is a two-part fiddle block ( www.duckworksbbs.com/hardware/blocks/rl378/index.htm). Between the fiddle block, the lower sheave on the car, and the block/clamcleat combination you can work out an (I think) four to one adjuster using a single line. I won't try to describe how the line runs, but it's quite simple to figure out once you start. Both Duckworks parts are quite inexpensive, nothing new needs to be attached to the transom, and I find that the load on the tensioner is quite low even when the forestay and backstay are fully tensioned. I've used this setup for two seasons now with a CDI furler both racing and cruising under a variety of stressful conditions with no problems.

Definately go with the split backstay adjuster. In addition to your mentioned advantages if you have enough slack in the backstay it is much easier to pin up the forestay. Eldor M17 Motu iti

Has anyone with a M17 with a CDI furler toyed with installing a backstay ensioner? I have my backstay tightened down as far as the turnbuckle will llow but notice that the headstay/furler looks a little limp. To compensate I ightened up the headstay but now I have very little rake, if any. I've seen ecommended rakes as much a 12". 'm thinking that a backstay tensisoner might kill two birds with the same tone..... tighten the forestay and create some rake??? 'm thinking of using a pincher design using a 4 part purchase to tension a pair f blocks to ride down the split stays. Has anyone tried this? Are the ttachements at the the deck for the split backstay strong enough to handle a ackstay tensioner? Am I toying with danger that might damage any of the rest f the rigging?? Any advice is always welcome. hanks, oe 17 Seafrog #651 ______________________________________________ ttp://mailman.xmission.com/cgi-bin/mailman/listinfo/montgomery_boats Remember, there is no privacy on the Internet!
