Sailworks Revo '99 rigging

Hi
I've got a '99 Revo that i rig on a 430 mast as i haven't got the
recommended 400. I have been downhauling until the batten above the
boom cutout is mid way along the mast and visually the leech does not
go very loose. The sail also felt really stiff rigged this way. Could
this be the mast, although the 430 is not first choice Sailworks do say
that you can use it as an alternative. If i downhaul to the max
recommended with the batten just touching the mast the leech seems to
be much looser. I am 80 KG's, does anyone have any advice on rigging
the Revo? Also, i use a rigging crank and even with that it is a real
effort downhauling the Revo. Much harder than downhauling my 8.5 Mtr,
seems strange.....
Cheers
Paul

What size sail is it and what stiffness is the 430 mast? It might be
too stiff.
I have the wrong masts for some of the my older revo's but the stiffness
is correct and find that cranking the downhaul until the leech is looser
works fine. That way gusts will twist off the sail. I'm quessing that If
you can find a 400/18 the sail would then work better, but with a loose
leech you will have fun. I always use a crank, that's perfectly normal.
Just use the pictures in the rigging quide to gage leech looseness.
If you do not have the rigging quide they are availible online at the
sailworks site.
Also make sure that the battens are tightned properly before each
session. Otherwise the sail will definately let you know it's not
happy. (twitchy center of pressure shifts.)

Then go out, put all your weight in the harness and hang on.

Thanks Tom, the sail is a 4.2 and the mast is a Gun430/IMCS21

What length are you setting the extension strap to?

Not sure exactly, but when i rigged it to the max with the batten above
the boom just touching the mast, the pulley was maybe an inch above the
mast base pulley. I just try and get the gap between pulleys as small
as possible.

Re: Sailworks Revo '99 rigging

I'm certainly no expert, but I suspect that you will be so much happier
on your fine classic Revo if you use a smaller mast. All of my small
Revos are elderly, but still perform beautifully. I use a Sailworks
370 Lipstick on my 4.2, although I'm very light and a 400 of good
quality would probably be good for you. It also makes a difference if
you are putting too much of the extension up into the mast - when you
don't need much extension, you might try a stubby to reduce unnecessary
stiffness at the bottom of the mast.
I rig all my Revos so that the batten above the mast slightly overlaps
the back of the mast before I apply the outhaul, and that the outhaul
is just a centimeter or so past neutral - I then fine tune to the
conditions with the outhaul. I understand your reluctance to buy a new
mast (or a decent used mast), but the pleasure you'll get from being
rigged just right, particularly in high wind conditions, more than
makes up for the expense.
Hope this helps -
Lisa

Re: Sailworks Revo '99 rigging

Paul,

I second Lisa's recommendation on matching the sail with the correct mast,
maybe even consider an RDM. I sailed my 5.8 2003 Revo on a 430 cm SDM wave
mast (PowerEx) for a couple of years and came to appreciate how much a
different mast can change the feel of a sail when I switched to a Sailworks
430 cm RDM. While I could dial the 5.8/SDM combo to achieve desired power
over a great range of wind speeds, the sail always felt stiff. Upon
switching over to the 430 RDM, the rig is so much smoother with gusts
dampened out very nicely. There has been no noticeable no loss of range or
speed.

If you still want to use the 430, try downhauling per leach looseness
instead of batten tip position. Back when I had a 7.5 and 6.5 Retro (PowerEx
460 75% SDM recommended for both), the 6.5 leach did not loosen up as much
compared to the 7.5 leach for the same batten forward tip position. The 7.5
would rig exactly as described in the SW rigging guide whereas the 6.5 leach
looseness/batten tip position did not have the same relationship.
Consequently, I would apply more downhaul to the 6.5 and rig it per leach
looseness rather than batten tip position.

Hope this helps.
Best,
Matt

According to the specs at
http://www.sailworks.com/06/previous/1999_Specs.cfm#anchor471372
you must be talking about the 4.2 or smaller. I had a 5.4 99 Revo that
I rigged on a 430, and I found that even at my weight (95kg/210#), that
mast was about as stiff as I'd want it. So yes, the 430 is an alternate
mast, but yes, it will make your rig feel very stiff. Extra downhaul
will help, but there are limits to everything.

If you're looking for a strategy going forward - get yourself a 400cm
Backbone RDM. It should work very well in the 99 Revo as it is designed
to emulate the bend curve of a SDM, and it will be much more responsive
than your 430. And when it's time to replace the sail with a new one,
you've already got the right mast.

Re: Sailworks Revo '99 rigging

Thanks a lot for all your replies, it's gonna be absolutely howling
tommorow down here so i should get to try out a few different settings.
If it still doesn't feel right i'll have to get the credit card out and
go shopping for a 400!
Cheers
