Must be some fancy fitting if it costs £80.

I've seen plenty of these used on Phantoms, carbon sealed mast and external halyard, and at £3.29 are a lot less expensive.

You need a knot for that though.

We used them on our 505, it does a couple of things.  First off as mentioned there is no halyard tension running through the mast, secondly you are guaranteed the mast is hoisted to the correct place every time, also there is no halyard slip when you crank on Cunningham.

I suspect we're talking an internal halyard and lock rather than an external.

On Finns now most manufacturers use them as standard and they work very well. The ball on the wire strop wears and really isn't noticeable, so I always keep a spare in my kit. Having had a new one stick at the Dinghy Show a few years ago, I would recommend close inspection, cleanliness and maintainence, there is nothing more frustrating than having everybody pulling there stands down and you still having a fully rigged boat that you need on its side without enough bodies to do it. Happy days, role on first week in March Smile

I made one for my Canoe that doesn't use the ball and ramp, instead its got a trigger release and its all internal. You can use it with a rope halyard - it just needs a shackle on the end to engage. Seems to work OK so far, but its got a lot of components and would be very exepensive if manufactured.

Mine is just an open cleat that the halyard jams in. You need a little slack in the system so you can pull it downwards to release but not much. I also have a cleat at the bottom to take up the spare halyard.
Everything I say is my opinion, honest

the megabyte has the same system as the byte and also the europe.  If it works on a finn and a europe I'm sure it would be transferable to an ok.

there is a halyard lock in the p&b catalogue at £77!

I think I am going to try the phantom style system on the contender, not least because I hate rethreading halyards when it all goes wrong.

Recommendations for the right sort of string?
the same, but different...

Ian, is yours an external halyard then? Is the cleat on the side or the front of the mast?
 
Just curious to give it a go and your system sounds potentially the cheapest/easiest.
