Tensioning frac rig with swept back spreaders

[mikehoyt]

HI. Have Hinterhoeller Niagara 26
I purchased a Loos tension guage and it stated for 3/16 wire to tension shrouds to 600lbs.

On my boat I thought this a bit excessive but tried. Seems to now move well upwind in windy conditions and waves. Seems slower than before downwind esp in lighter winds.

Am planning to ease the outer shrouds 1/2 turn on turnbuckles.

Comments?
