Clew block for reefing main

Sorry to start a new thread on the well worn subject of reefing..but I have been googling and searching for at least an hour now and haven't found what I am thinking of

I remember reading about blocks that can be sewn in ? to the clew of a new construction main to aid in reefing. I seem remember the manufacturer wasn't one of the big ones. Anyone know?

If not, anyone have a good solution for blocks to attach to the clew?

Sailboy-

Blocks aren't generally attached to the clew or leech of a sail. Occasionally, small blocks will be attached to the reefing cringles to lower the amount of friction in the reefing system. However, I'm not a big fan of them, since they can chafe the sail near the cringles.

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.

I don't like the idea of blocks either, however the product I saw served as a replacement to the cringle, probably less weight too.. Just can't remember! Had a backing piece which was somehow fixed to the clew, and incorporated a sheave somehow.

What you saw was being developed Martin Van Breems, the inventor of the Dutchman. I was also interested in that reefing system, but after speaking with him several times, it seems that he's given up on it.

What is it about reefing a mainsail that makes a clew block necessary?
