furler jamming; halyard wrapping around

I have a halyard restrainer but it's not very low down so the angle of the halyard to the furler isn't very great and we are getting jamming due to halyard catching and turning around the foil

do I need a lower halyard restrainer or should I pop a halyard deflector on - I had thought a restrainer lower down to get a greater angle but maybe a deflector would do it?

confused of portsmouth

thanks!
 
sail's all the way up yep :) newish sail tho as previous sail was only a 90% jib and we've gone for a 135% which might have something to do with it
 
I've just got to the strop answer via google :)

thanks Bob - this weekend we'll hoist the old jib and check for issues and note the distance to the top and then re-fly the new sail and have a butchers - but I think that could be the answer :)
 
Did the previous foresail have the same problem? If not then are you sure the sail head is high enough? I had a new sail and needed a short strop on the tack to ensure the head was high enough.
Also is there enough halyard tension?

It is generally recommended that the angle between the halyard and the forestay should be between 15° and 25° ... but no more than 25°.

The deflector wheel fitted to the top of the spar by Plastimo, and one one or two other makes, is a convenient way of deflecting the halard away from the forestay in DIY installations where the spar is being fitted to an existing forestay without climbing , or lowering, the mast.
If you can access the top of the mast, especially if the mast is lowered , a fairlead fitted to the front face of the mast to give the required angle between the halyard and the forestay is likely to be the more satisfactory arrangement

Fitting a short lanyard to the tack seems to have cured a similar problem on my boat - I thought the angle & diverter was sufficient but I was wrong (I didn't want to clamber up the mast to check angles etc).
 
Also make sure the bearings in the swivel are clean and free of any gunk or corrosion. A few years back my Facnor became sticky and sometimes wrapped. Took it all apart, replaced the balls with Delrin and cleaned the bearing races so that they shined. Not had a single problem since then, even although the halyard angle onto the swivel is not big.
 
I spoke to the Selden guy at SIBS about a similar issue, and his first question was "do you have a new sail". This is, as others have said, almost certainly where your problem lies.

I recently had a problem with halyard wrap. The top bearing on the furler was jamming up.
