Just came across a reference to this on the Northshore Owners Facebook page.

Whilst I'm not contemplating changing to it anytime soon I had never seen it before and just wondering if anyone has used it and what they think?

I just wish my sail would fall like that

Yes my boom bag and lazy jack's weren't enough to make my sail flake nicely but then I figured out that I was winding on the topping lift too much and now that I leave the boom more horizontal the result is a lot better although still not perfect.

Drilling all those holes in your sails is the main drawback.

As others have said, lots of holes and string. We are lucky enough to have Harken cars on the mainsail luff, a stack pack, lazyjacks and a couple of full-length battens in the head of the sail. It's awesome; just drop the sail and zip it up. Having spent many years wrestlng with flaking or rolling racing mainsails, the stack pack/lazyjacks/ball bearing car system is awesome and doesn't have the problematic holes.

We had a dutchman system on our Catalina 320 when we first bought it. Hated it, too many lines and our main was in reasonably good condition so it never flaked well. When we replaced the sails, like Chris we opted for a stack pack, lazy jacks and battens. Much easier to use.
