Thank you.  Yes i will post photos.  Need to find them.  Yes the new sprit will be a wishbone.  I thought I had  posted a pdf.  I did but it is in the text for some reason.  

 

Will fix that.  I will be back..

Reef lines: The purpose was to reduce the effort required to reef. This is my mizzen sprit. The reef lines are on one side of the sail.  They attach to the reef point with a ball with a figure eight knot. Also I used a block on sprit to lead lines to the cleats.   Not a big change from original set up.  It is better not perfect, at least for me.

So normally the line goes through the reefing grommet and to the other side of the boom. Is the advantage here is that the friction of the line is reduced by the pulleys?

It's usual to have the mini block hanging aft, off the leach, usually by a loop or gasket of line, then to dangle down one side. I'd imaging this will work as well, if a little more wear and tear. The trick to this setup is the location of the turning block and eye strap on the boom. I like them a little aft of their location on the sail so they pull aft a bit, when hauled down.

With the sprits, the snotter should force the new foot of the sail tight more or less regardless of where the block on the sprit is located in relation to the cringle, as long as your snotter is adjustable and tightened when you reef.

Thank you for the comments. Yes the idea was to reduce friction. Since the sails stays on one side of the sprit it is possible to have the reef lines on one side and not through the grommet.  I attached my reef blocks on the sprit in according to B&B drawings.    I co-opted this set up from my 

Wayfarer.    We use similar kind of set up on the boom when we use it with reef-able  main.  I think it is an improvement, but there are always better ideas.

How are you planning on making the wishbone sprits?  Bent laminations (clamping the laminations together utilizing a curved form)?
