Tight single line reefing

My Hunter 326 comes with 2x single line reefing for its Mainsail. Increasingly, I finds it tough reefing and even tougher shaking out the reef. Many-a-time I've to pull clear the reef line from back of the boom. Any advise on how to "lube" and make the reefing lines freer ? Much appreciated.

Are you running the reefing lines through the clew and tack reefing cringles on the sail, or are you using blocks, like this:

I use the cringles. No blocks. Would blocks help ? The red tap and ring on the leech, did you buy it or made it ?

Blocks would definitely help! (Especially ball bearing blocks).

I made up the red webbing strap with the two rings, but you could possibly skip that and just shackle the block directly to a ring on the opposite side of the cringle eye. The Seatbelt webbing is just there to keep the blocks from flopping around.

Very interesting setup...I would think you could do away with the mast fair lead and come straight from your stand up block....You would loose a little forward pull but not that much as your boom block is well forward... The further forward the stand up block was to a point the less loss of forward pull

Very cool detail on this thank you ..I have been scratching my head on what to do myself..

Would moving the luff attachment point up another foot basically offsetting the reef points by one foot alow for a better fair lead or would the single line system just try to balance it back out anyway?.. I wants too work in my mind..

spraying the cringles and sheaves with McLube SailKote would probably help to some degree... but adding blocks would be a better solution. However, you really do need to make it so that the blocks don't chafe the sail where they're located.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Omatako will become famous soon enough
Whilst I have to concede that blocks would take some of the friction out, if the single line system is tight there is another reason for it and you need to find it. If not, the components that are causing the tightness will eventually break.

A properly operating single line system should not be tight.

Personally I would not put blocks on my sails simply because it complicates a simple process and this will cause me some worry. Each to his own, I guess.

Forget to mention, FWIW, Antal in Italy makes special "Reef Blocks" intended for attachment to the sail; probably only viable if you were having a new sail made.
