Neil Pryde V8 cams keep popping off

[Knut Aksel Sęthre]

Last year I bought a -97 7.5 NP V8, and while once a joy to rig, in
recent weeks the sail has become a real pain. The two upper cams keeps
popping off when I insert the mast, this happens befor I have the chance
to apply any downhal. The mast is the recommended NP CK55 490/28.

Anyone else experienced the same thing? How can this be fixed?

Regards,

Knut

Have a VX Ltd. Lots of cams. Find it best to have your extiontion
ready and your dowwnhaul. Keep the pressure on the sail all the time.
Let the pressure go at any time the sail rides up and the cams go pop.
Dont be too tempted to try to push them in as you may snap the battern

Knut, its not clear how you are inserting your mast. Try placing the base of
the mast against a solid object, such as car tyre. Then insert the mast into
the luff tube. Thread all or most of the sail on the top half of the mast.
Then hold the sail near the bottom camber, and push the sail down the rest of
the mast (this is why the mast needs to be against the car tyre). The cambers
should slide down the mast without popping off because there is no batten
tension until there is tension in the sail panels. If you try to pull on the
sail at the downhaul before all or most of the sail is threaded onto the sail,
the batten tension will pop the cambers off. In this way, the V8 rigs about as
easy as a RAF sail.

Cheers, Bob

I to have had the same problem. The way I find the best is to slide the
mast all the way without ever letting the mast or sail touch the ground.
When the mast is all the way thru ( keep you extension close by ) slip your
extension in and thread the line thru. Do all this without any of the
battens touching the ground. Begin to pull the downhaul. Once you have
some downhaul pressure then you can lay it on the ground and continue with
the rest of the downhaul. Works everytime for me.

I am wondering how do you insert the whole mast without the mast or the
sail touching the ground, specialy when the sail is a V8 7.5 or like
mine, a VX2 7.1
.

Again, how do you do that?

You can do this without letting the mast or sail touch the ground! Boy, you
must be pretty darn tall, and strong too!

But seriously, I had a problem with the top one popping off. When I opened the
zipper and had a look at it, I noticed that the cam was attached loosely with
a small strap using a knot. I just untied it, took out some slack, and retied
the knot.

As long as i remember, if its a big nielpryde v8, the cams will pop.
Its also like bad wine..it gets no better as it ages. .
all my V8 do this - and they ARE on the recommended masts
(usually a 490 or 460 CK55)
I love these sails, but the campop is a design problem that needs to
be addressed by nielpryde.

My sails include;

1992 7.5 (2 cams, pop off 100% and now a true pain)
1994 7.5 (3 cams, not so bad- 25% pop off rate)
1995 6.5 (3 cams also not so bad)
1996 8.5 (3 cams getting close to as much a pain as the 1992)
1996 5.5 ( only 4 pops in about 25 uses)

I have a VX2 7.1 and the first time I rigged it, it was a disaster. I
realized that whenever I raised the mast-sail from the ground while
threading the mast into the sleve, the battens were more bent (the mast
20'' above the ground and the extreme batten tip touching the ground),
and the cams will pop out.

Then, I inserted the mast just applying pressure in the bottom
of the sail, wihtout raising or lowering the mast (if done that, the
pressure in the batten will pop out the cam). I managed to thread the
last yard of the mast and extension just downhauling the sail with the
line, and voila! the sail was rigged in less than one minute, even the
male cap of the sail went nicely into the female cap of the mast just by
himself.

All of this was in my backjard. Last thursday I was in the lake
and I tried to repeat the same procedure. Invariably, one cam popped
out, and the rest after the first one. Everytime, I had take out the
mast and start all over again. After one hour, I quit this procedure and
apply a more brute force one that worked right away. This time I just
slided the mast into the sleve without worrying about the popping out
cams (the more cams out of place, the easier to slide the mast in the
sleve since there is no pressure of the baten-cam in the mast). I
downhauled like 90% and I ATACHED the BOOM. I APPLIED THE MAXIMUN OTHAUL
TENSION and then, I started to pop in the cams into place (I had 6 cams
out of 7), STARTING from the TOP ONE. the top one is the easier to pop
in (by pushing down the baten like 10" from the cam) because it has the
smaller baten and the less presure in the mast.

With 6 cams out of place the mast was strait, but just placing
the top cam into the mast made the mast to take some of its curvature,
which in turn, helped to place the following cam (the second top). The
more cams go into the mast, the more the mast bends, and along with the
outhaul in its maximum setting and the sail not touching the ground
because of the boom, helped to pop in the bottom cams easily.

Then, just downhaul all the way and readjust the outhaul

I hope this method will b next time repeateable

I have an old VX 6.3, after having problems with the cams coming off I
rig my sail:

1. release bat cams on 3battens above boom and one under boom (that
leaves the top two done up and the bottom one also.

2. SLide the mast up the sail, trying to keep the cams on the mast, the
pressure of the mast pushes the released battens out a bit.

3. Get the sail fully on the mast, not worry too much if the cams pop
off. Apply 90% down haul

4. Put the boom on and outhaul a bit extra.

5. Do the battens up starting at the top of the sail. It helps a lot if
someone else can make sure the cams stay on and the batten feeds in
nicely.

6. Finish outhauling and down haulling.

7. Sail.

Pat.

I have a quiver of Pryde sails and on a few of them the cams come off
while rigging. Talked to the guys at Maui Sails (where they are
designed) about it and they showed me a better way.

Slide the mast in as far as it will go.
Go to the top of the mast and pull the mast up until it seats in the
cap.
Work from the top sliding the top batten down until it is tight and
then slide the second batten down until it is tight etc. etc. You
have to move the lower battnes down a little during this process to
take up the slack, but dont't pull them hard or they will pop off.

One thing I've noticed is that the sails I have that tend to pop
cambers while rigging are the ones that have been left rigged, but
with a losened downhaul for weeks at a time. (I don't do this any
more)

If you want to ask Pryde directly the E-mail address address of Maui
Sails is: maui...@maui.net . Direct any questions to Gus Taylor
or Kevin Ozzy.

I have an older V8 (1992) and had no problems at all until last year.
Upon inspection I noticed that both cambers we cracked (unrelated) and
replaced them with the new roller cams which popped off every time!

Now I rig like Tom (earlier respondent): slide mast up beside cams,
down haul lightly, attach boom, outhaul strong, pop cams on, set
downhaul and outhaul. Works every time.
