Rigging Details - Spar and Boom

The designer, Ross Lillistone is a fan of simplicity attaching a halyard to the spar. He advocates tying it directly using a clove hitch. This works well, and is very simple. However the spar can pull away from the mast. It can pull away from the mast even more when any reef is put in the sail. Ross recommends a 'snotter.' Here is the snotter design from Ross -

I tried this approach with the boat on a trailer in my driveway. The only difference is I used a bowline knot instead of an eye with a thimble as is shown. It worked, but required a little more effort when lowering the sail as you had to loosen the snotter first before easing the halyard.

I found another method that small boat designer Michael Storer (designer of the Goat Island Skiff and the OZ Goose). Details from Michael are here

While this is a little more complicated to rig, it does keep the spar against the mast no matter where the spar is on the mast. I attached a ring to the spar using a dyneema loop.

The halyard comes down from the top of the spar, through the ring and forward around the mast and attaches to a loop on the forward end of the boom.

To keep the boom near the mast I used a small dyneema line with an eye at both ends. One end goes around the boom (and through the first eye) to form a loop around the boom. The line is led forward around the boom - 

And attached to the front of the boom -

I have been using this setup for a while and I find it is easy to rig and keeps the spar and boom close to the mast.
