[frers-list]Rig tensions

[Bruton, Tom (GECAS)]

Scott, when you say less than an hour, are you assuming the mast is down? O=
r is it just the roller furler that's being swapped out - I assume an actua=
l head stay change cannot be done by a trip up the mast?
Tks, and sorry if this is stupid question,
Tom Bruton
F36 owner with the same problem

Mike,
Risoluto had a Harken MK2 for the first three years I owned her.  I had the=
 same issues as you with regard to bottoming out the threads and not being =
able to tighten any further.  The boat did not point well and I was never a=
ble to remove the headstay sag in medium or heavy air.
In year four I removed the roller furler and installed a new headstay with =
a twin foil.  The boat was instantly faster and pointed much higher.  I reg=
ret not making the change sooner.
If you can own two headstays, and have a way to store the furling headstay,=
 you can swap them out in less than an hour.  This gives you the chance to =
change from racing to cruising mode in a very short time.=20
