Change of sliders on the
main sail
As you are probably
already aware hoisting the mainsail is not easy to do. Same for hauling
it down.
Paying for a gym membership during sailing season has been a waste of
money. The vocabulary also declined and at the lowest point the language
was more like a pirate's and that was just my wife. My language was not
much better but my wife and I seldom discuss that period!
After
testing Teflon spray without much success, we tested dishcloths soaked
with Teflon spray that we stuffed in the mast track (thanks to all of
you on the Hanse forum who gave the good advice!). Wow, that was like a
rebirth when the sail flew up in the top of the mast and coming down
like an avalanche in the mountains!
But,
Christmas lasts only a day and so does Teflon spray. The option to
purchase a Strong Track was not an issue but Peter (also a 370 owner)
gave a tip that was simple and would only cost "about" 100 SEK.
Peter
and I have we have different definitions of "about" :) As it turned out,
to re-sew the sail was cheap at SEK 1.600 including Cunningham ring.
This is only 10% of what a Strong Track would cost which North Sails
suggested as a solution.

1.
This is what the sail looked like before anything was re-sewn. |
|
2. As you can see the sliders were sewn very tightly to the edge
of the main. This made them twist and cause friction in the mast
track as there is no room for movement.
|
3. Detail picture
of stictched sliders. |
|
4.
The old sliders will be replaced with new ones that are attached
to shackles. As you can see there is now space for slider to
freely move up and down and will not be twisting inside the mast
track anymore. |
5. Old slider is
removed. An eyelet is punched into the sail.
|
|
6. The eyelet is
off course stainless and very nicely fitted! |
7.
The sliders hangs relaxed from the sail after been replaced. |
|
8.
The sliders for
the battens have been adjusted slightly so they are the same
distance from the mast as the new sliders.
|
9.
A Cunningham was missing from the sail so the sail maker fitted
one. I did not have a clue what it was but it looked cool...and
these days I of course know what it is used for.
|
|
10.
Detailed picture of the eyelet called a Cunningham. |
11.
The first slider on the top clew was left as it was as the clew
board kept it straight anyway. This has since worked quite well
without any problems. |
|
12.
After re-stitching the sliders the sail comes down easily and
stacks nicely on the boom. There is no friction or tension on
the sliders which makes the down hauling of the sail quite
effortless.
|
13. The sliders
stack closer to each other as there is more room for them to
move freely. |
|
14. We
can now hoist the sail without any problems. Both my wife and I
are able to manually hoist the sail until there is only 20 cm
left and then we use a winch. Strangely my wife's language
improved immensely with the new sliders when she hoisted the
sail manually to the top first time. I had just started to get
used to her sounding like a drunken sailor.
|
15.
The sail is little bit further away from the mast with the new
sliders when having the wind from the bow but when the wind
comes from the beam the gap between the mast and the sail is
smaller. Better or worse, hard to say but we haven't noticed any
performance difference.

Conclusion:
Changes to the sail proved to be the best changes we've made on the
boat. This solution should be standard on our boats. The cost is minimal
even if you pay it yourself. The sail can now be hoisted by one person
and in difficult situations it is easy to just drop it! No more pulling
and climbing on the mast or using boat-hook to get the sail down!
The downside? Well, I now have to buy a gym card for the wife. |

Since the last changes were documented on this page we are back to the
situation where hoisting/lowering of the main sail is not as smooth as
we were used to. Cleaning the mast track and spraying everything
with Teflon has not been the optimal solution. Our beliefe is that the
problem lies in the batten sliders and therefore we have decided to
change them to Battcars. If this doesen't help the next step will be to
install a Strongtrack. |
1. This is one of the sliders. We have four on the sail, one for each
batten. |
|
2. The slider when not fitted in the sail. |
3. The new Battcar from Rutgerson. See product information below.

The batcars have now been fitted to the main sail and the result was
waht we expected. Hoisting and lowering the sail is now easy and safe
and it has reduced the stress on the boat somehow as we don't have to be
worried anymore if the sail will come down or not. |

The batten rests now on the wheels and lowering the sail is just pure
fun now! |
