Genoa UV strip vs coils on reefing drum

[Chae_73]

I seem to be a bit stupid here and I can't quite work out in my head how or why this is happening.

To achieve the correct angle of the furling line coming off the drum, I want it to exit on the port side of the drum. But if I furl the sail to achieve this, the UV strip on the wrong side of the sail.

Is there a way to solve this?

Thanks in advance.

Can you explain why the direction of the furling line on the drum makes a difference?

 

[Refueler]

OK ... first of all .. What Furling system do you have ?

Most will allow line to come off either side - to port or starboard. It is common for it to be Port - but that's only a convention - not a rule.

If you are so determined to have line come of as you say - then you will have no choice but get sailmaker to change the side of sail UV strip is on.

I agree that direction of rotation isn't fixed. It wouldn't furl and unfurl if it wasn't able to rotate in either direction. I imagine that you can set the guide to be on either side to run back on port or starboard. I suspect that turned the drum in the wrong direction when you put the line on.

Easy enough without the sail as you just rotate the drum by hand in order to wind on the correct number of turns. It is a bit trickier with the sail up and if you don't know the correct number of turns either.

I make it easy for myself by having a note of both direction and turns to avoid winding on incorrectly. I'd bet that someone simply wound the line in the wrong direction before hoisting the sail. Count the number of turns required to furl/unfurl and note for future reference.

Thanks. To answer some of the questions:
Make of furler unknown. Any branding that may have been on it seems to have worn off.
It has no guide eye for the line.
I want the line to leave on the port side of the drum to avoid pulling against on the the stainless bars which enclose the drum, it looks as though that's how it is supposed to work.
I have tried completely unfurling the sail but if I was then to furl it in the opposite direction, the UV strip would be on the inside of the sail when furled.
It seems that @Refueler has identified the issue.
As I'm having another headsail made, I guess I can correct the problem with the new sail.
First season with this boat so on a voyage of discovery!

Can you provide a photo of your furler drum ? I am sure we can identify it or at least advise what may be possible.

OK - question : Did you buy the boat with this already at fault ? Did the drum ever get taken off to service and may have been put back wrong ?

Eye's or guides are usually for open drums such as the 406 .. 609 .. and similar Plastimos ... my closed drum Profurl did not have eye or guide ...

Its easy enough to create a guide - by mounting a small line block on the pulpit upright to feed the line to the drum .. i have this as well as the Plastimo wire frame guide on the drum.

Here's a picture of the line exiting the drum.

Not sure if it was like that when we bought the boat. Since then, the mast has been down, sails removed, valleted and repaired.

Here's a better shot

OK .. looking at your photo ... I have no idea what brand of furler that is - BUT the solution should be easy.

The furling line can easily be on the other rotation so it comes off other side of the vertical wire frame. I would also suggest that having such a long lead back without guide causes the furling line to rub on the wire frame vertical. I would be inclined to fix a small line block to the stbd pulpit stanchion so that line is guided to the drum clear of the frame ...

Here's your present with line rubbing on that frame ...

Here's a suggestion with the block fixed to the stbd pulpit upright and line wound on opposite rotation :

Note that line will now feed clear of wire frame .... furler will rotate in other direction and UV strip will be correct on genny. (Excuse my quickie copy - paste to create a stbd side pulpit etc !).

I would suggest that if you have another genny and are keeping a port side line out - fit the block to port pulpit upright to avoid that rubbing on wire frame ..

If you look do you have two slots for the sial to go into?
You might find it is in wrong slot, when I put the sail in the wrong one on my boat it was then at the wrong angle to furl in the correct direction.

It is very easy with the sail removed and you know the number of turns required to furl. Start with the line fully out and manually rotate the drum to wind in the line. Think carefully and wind it in the direction required to pull the sail in with the UV strip on the outside. It should be easy because the sail is already up and the current direction is wrong. You want to go the opposite way and can also count the turns before removing the sail.

The line will be fully wound on before raising the sail. If the UV strip is on the stbd side the line must pull the drum anti-clockwise and the opposite if the strip is on port side. It makes no difference whether the line is guided down port or stbd deck. The direction of rotation when winding it on initially is the important point.

You can manage it with the sail up but you will need to remove the line completely and wind it in manually and go several turns too far, winding the sheets around the sail. Remember to wind the sail with the UV strip outside. Re-attach the line to the drum and it should be fine.

Interesting .. what furler was that ?

I've only ever seen two slot when its Profurl (one slot for sail and other for the halyard / furler line) and second when its racing foil for quick sail changes ...

Can you not just take the line to the other side of the frame member it's bearing on?

It would still be wrong rotation. He needs to wind it on other way ... in fact I can see a revision in my earlier sketch ...

Further looking at the original photo - the line rubbing on the frame means it is wound on wrong direction. So remove the line and wind on opposite direction still staying in same slot of wire frame ... the line then stays on port side and has a better lead to the drum. It could even not need the small block I suggested.

 

[Stemar]

Just do what I do. Wind on the line, then add the genny so the UV strip is on the outside. Pull the line to see if you got it right. You didn't, so tie up the genny, unwind the line and keep winding in the same direction until it's back on. If you need to fiddle with the run of the line, fiddle, adding one of these if necessary.

Refueler has it - its clearly wound on the wrong way. Have the line led on and off clockwise.
Looks like a Profurl.

I thought the point was that if it was wound that way around (i.e. rotating anticlockwise looking down from the masthead when you pull the string), it would wind the wrong way for the UV strip. It's rigged like it is so that pulling the string causes it to rotate clockwise, putting the UV strip on the outside.

Go back and read first post. He says that wound as it is now - the UV strip ends up inside the furl instead of outside the furl. Second - the furling line is fouling the wire frame - indicating its wound on wrong.

Not sure I agree @Refueler

The OP wants it to come off the port side of the drum. (post 5: "I want the line to leave on the port side of the drum to avoid pulling against on the the stainless bars which enclose the drum, it looks as though that's how it is supposed to work. ")

However if they do that, it rolls the sail the wrong way for the UV strip. Hence why the line is taking the convoluted route it is now.

That's how I read it anyway.

As OP said himself - I had it right ..... and he said to stay as it was - the UV strip would be on other side of his new sail.

So that shows that the turns are wrong way round. If he corrects the turns so they enter and hit drum on its port side - he gets both .. line exiting port and the existing sail UV strip correct.
