caledonia yawl project: late fall tinkering

COVID has meant that the big move out of the boat is delayed. But I don’t want to lose momentum. So I’ve started to think about the rigging in anticipation of getting started on the spars in the spring.

I’ve decided that with the new Dyneema materials it is a nice way to simplify the rigging and keep it light and strong. So I ordered some materials and a splicing tool to start practising my splicing and work through what I want to do.


I started with 4mm per-stretched heat treated Marlow Dyneema line that I’ve made into a few soft shackles and a strop.


I was also inspired by the article in the latest issue of Wooden Boat magazine #277 by Harry Bryan on a more accurate spar guage.

as it turns out that is my next upcoming task. So I set to work with a few pieces of my reclaimed cherry wood and the prescribed parts for making the tool.

Not yet quite as pretty as Harry’s example but with a litle finish work it will get there.

I’ve also ordered a few sheaves with the idea of making a modern composite wood rope stropped fiddle blocks for the mainsheet with Dyneema for the strops. If my idea succeeds they will be light and look at home on the Caledonia Yawl. This was inspired by the illustration for rope stropped blocks in Brion Toss’ Riggers Apprentice book.

The cheeks for the moment are 1/2″ reclaimed cherry wood that is hard and easy to work with. All I’m missing at the moment is the rod for the bearing of the sheaves. The strops will be made of 6mm Dyneema.

I’ve also have to make or find some thimbles to complete the block ends.
