[Passport] stay tensions on a p40

[dennis]

Hola everyone
I just removed and repaired my roller furler and tensioned it back up.
but I don't want to go too far. It hadn't been properly tensioned by
the previous owner. Does anyone know the ft/lb numbers or something
else to go by? Especially the backstay.
Thanks all
Dennis

Hola Dennis, Que Pasa?

On Cayenne, a 1984 P40, there are several considerations

1.  Take the sag out of the forestay.  This requires about 1000 lbs in moderate weather to about 2000 lbs in heavy upwind work.  Beyond that, you're just bending the hull.  Jack Bieda on Trial Run used to say that you did not have the backstay tight enough until you couldn't get the forepeak door closed.

For downwind work, I ease the forestay alot, for sail trim reasons. There is little point in trying to bend the mast, but you can move the masthead, if that floats your boat.

2.  The shrouds.  I had an odd inverted mast problem, so my forward lowers are rock-solid while my aft lowers are pretty slack.  For the uppers, I got them even and pretty solid feeling and then went sailing to see if things looked right.  Ferenc Mate's "Shipshape" describes rig tuning very nicely.

Good luck

Michael
