Genoa UV strip vs coils on reefing drum

[Refueler]

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.

OK lets see if we ca clear up ...

What side is the UV strip on your existing sail ?

If you furl with the line set as you have in photo ... which shows it coiled ANTI-clockwise - does the sail furl and have UV on outside as it should be - or on inside ?

Those two answers will give us the clues to finalise.

Hint : If the UV strip is on the port side of sail - then it needs to furl up CLOCKWISE to have UV strip on outside. (Someone may correct me - but I think if it is port side UV - then its unconventional - most I know are UV on the stbd side of sail)

Your line at present turns the drum / foil clockwise to furl - but has the line rubbing on the wire frame. Therefore if its correct rotation - you need to add a small block to port side pulpit vertical to get that line away from that frame... OR lead the line down stbd side on other side of that wire frame vertical.

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

Yes, Refueler's picture helps explain exactly what I've been trying to say in my earlier posts. People were still talking about the exit angle of the line. You only need to do something about the direction of rotation and ignore the angle. The angle only becomes important if you want to change which side the line runs and nothing to do with direction of furling/unfurling.

I've mentioned it in my earlier posts and tried to give instructions. Refueler's picture does make it really obvious.

My post above doesn't all make sense. Clearly if the furling line is led on clockwise, then it must come off counter-clockwise.

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 ...

Sorry I don't know the make.

I also wound the sail on plus a good few turns on the main lines.
I then attached the furling line, thus ensuring that when fully wound in there was plenty of the other lines to wrap around the sail.

I am completely confused now ... thread started by Chae_73 ....

Now have Mister E

?? Are we still answering Chae_73 or is that all done ?

I was just saying how I attached the furling line so that I did not have to worry about the direction that the furling line turned, with the sail the right way round when you unfurl the sail the line sorts itself out.

There seems to be a little confusion here (for me at least!)

I thought the OP was saying that the set-up as shown wound the sail correctly (with the UV strip - which is on the post side of the sail - on the outside.) His problem seemed to be that he doesn't want the line bearing on the frame of the furler. One suggestion the OP has for achieving this is to wind the line on the furler in the opposite direction: this won't work unless you also move the UV strip to the other - starboard - side of the sail. What would work, as I tried to suggest above, is simply moving the line to the other side of the offending part of the frame and then putting it back in its existing route to the cockpit.

The only fixed thing is the side of the sail that the UV strip is sewn on. This dictates the direction the sail must furl. You have no option unless you get the UV strip sewn onto the other side which is an unnecessary expense. The direction of furl rotation then dictates the direction the rope must go. Then you use stanchion blocks or similar to give the rope a fair lead from the last block onto the drum.
I don't understand what is so difficult in this to create two pages of debate. Refueler and others have already given the solution.

I think he said the opposite.

Or just attach a small block to the pulpit upright to lead the furling line at better angle

 

[Chae_73]

If you furl with the line set as you have in photo ... which shows it coiled ANTI-clockwise - does the sail furl and have UV on outside as it should be - or on inside ?

At present, the sail is furled the correct way, so the UV strip ends up on the outside. The problem is then with the direction of the coil on the drum.

My question was "is there a way to achieve the line coming off the port side of the furling drum without ending up with the sail furled the other way and the UV strip therefore on the inside?"

I think this has been answered in this thread and also by me unwinding the whole thing and trying it in the other direction. So.i think it's "no" unless I'm still missing something.

I could just put another block on the pulpit to improve things, or else run the line down the starboard side of the boat.

Many thanks for all the advice ?

 

[Chae_73]

Or as Thistle says, lead it out on the other side of the bar on the frame. Only slight downside to this is that the line is across the deck.

 

[Refueler]

Here's my line via a block to the side .. a bit further back than yours would be .. but shows what I mean ..

Your last post has cleared up the last bits and I would suggest just add the small block and let her work as is. If you do get another genny - then its easy enough to sort rotation as necessary with or without block etc.

Don't know if you have such - but I fitted stanchion blocks along the port side - when I bought boat all it had was that small line block up at bow ..

If you look closely at stnachions - you can see the furling line via the small blocks.

Looking at the picture of your drum the fixed frame which is causing the problem seems to be clamped to the stem head fitting, If you loosen the frame clamps can the frame be rotated until your line will miss the frame. If it can be rotated it will solve your problem. Which side of the sail is your U/V strip, port or starboard.

UV strip is on the port side, I think.

Here is a pic of the furler drum

I have spent many happy hours on a calm day rolling and unrolling my headsail to achive the preferred outcome. It can be done.

I think you may be mistaken.

From the photo it looks to me that (a) the genoa is wound on clockwise (facing downwards), (b) it is the port side edge of the sail that is exposed, (c) there is no UV strip visible, and therefore (presumably) the UV strip is on the starboard side of the sail.

The furling line is wound on the drum anti-clockwise (facing downwards), which is correct if (by unwinding the line) you wanted to furl the sail clockwise.

It seems to me that all you need to do is rewind the furling line onto the drum in the opposite direction (clockwise) as per Refueler's diagram in post #14, and this will solve both the UV strip problem and the line fouling the drum cage bar.

 

[Chae_73]

The UV strip is definitely on the exposed (port) side of the sail. It's white, which makes it less obvious as to whether the sail is furled in the correct direction.

I did have a good look at it whilst in the marina yesterday, and I'm sure that the sail as pictured is furled in the correct direction. This was also confirmed by the guys from Dolphin who were there fitting the sprayhood, and took a bit of an interest in our antics with the genoa.

Having thought about it some more, when I sent the sails to dolphin over the winter (having purchased the boat at the end of last season), they made a repair to the other side of the leech of the genoa, so it could be that the previous owners had the sail furled in the wrong direction for some time, leading to the observed damage on the side opposite the UV strip.

Looking at Post #35 picture - there does appear to be a slight twist to the lower chain plate to stemhead fitting ... but that will never be cured as the twist will re-assert it self.
Simple cure is that small block on that upright

Was the sail made for that furler?

I had a furler drum come unscrewed from the foil in a strong blow when I fitted and furled according to the sail which I had brought along from a previous boat.
