My spinnaker hoisting is slow due to friction. I've replaced all the cockpit blocks with ball bearing ones and might do the same with the mast sheeve. (already well lubricated)

Halyard is 4mm.

I've used silicon spray on the chute mouth

So the question is what next. The spinnaker has two patches, currently I rig them on the outside of the sail so the colours on the edge tapes match the side they are on.

Would it work better with the down haul rigged on the inside of the sail? Should I not bother with the lower patch? Any ideas?

If its an old kite that has lost its crinkly finish and gets all soggy, sadly the best solution might be a new rag.
The mast sheave does tend to be the most critical one and the one that takes the worst beating.

You must have down haul inside - if you have two patches.   Make sure the halyard can move easily through bottom patch.  I have just bought a new spinnaker (360ish) and it has holes not patches so top half can be on inside and bottom half outside which worked well last WE but that was first outing.

You need to stand up to hoist and drop quickly so tiller must be long enough to steer with legs.  This works till waves big enough to dump you in then the crew does the drop and the high winds ensure plenty of adrenaline.

You could also try spraying the whole kite with silicone.
A 4 can is cheap to try.
Test the blocks etc by taking the kite out of the loop, tie a bit of string between halyard and downhaul.
It could be friction inside the mast.

There are several things that can increase the friction on the L2 spinny so without looking at how it's rigged and how you perform the hoist/drop it's difficult to say. As Spike says, the patches go on the inside, here's a list of possible issues.


Rinse the salt (if you're on the sea) out of the halyard after each sail.
What going on with the guy and sheet when you drop/hoist?
Are you trying to drop and hoist on a slight reach?
The halyard goes through two fairleads and then the cleat jaws on the cockpit floor before passing through the steel hoop which you pull against. You are pulling the rope over that hoop at 90 degrees which causes loads of friction so decent rope that isn't too stiff makes a big difference.
Put a plastic parrel bead on the halyard between the first and second patch. This stops the knot at the top patch getting stuck in the loop at the bottom patch.
Is the halyard free in the mast? IE not wrapped once around another halyard. This can happen so easily if it's been re-threaded at some time.
If the spinny is old and absorbent (as Jim Says) it will be like dragging a dead body out of the shoot.

Just a few thoughts.

Thanks, really good points, especially about putting the patches on the inside and and the parrel bead.

Spinnaker has hardly been used. I'll check the halyard in the mast. I might be able to replace the cleat hoop with a small block I've taken off from below the mast. Smile

Try threading the halyard through the lower patch, then through the bead, then tie a stopper knot about 250mm from the end of the halyard, then pass through the upper patch and tie another stopper knot. That way you will not be trying to pull both patches into the chute at the same time.

Thanks Chris ,

pulling both patches into the shute at the same time is what is happening, so I'll have a go with your idea as well.

Yeah, spacing the patches is a good idea. It might be worth laying out the kite on a flat surface and figuring out what a good location for the stopper would be with view to reducing bunching but still getting it down the chute properly. A bit of whipping round the halyard where the knot will go is handy for repeating the setting. A good kite will have the patches located for the spacing.

One boat I sailed on, the kite was a pig to retrieve if the ratchets were not switched off.
Friction on the sheets can be as bad as the halyard.
