Got frustrated trying to make the batten controls worked, recut the old sail so I could go for a sail.
All worked a treat. Not much wind, but it got along very nicely until I broke a tiller. Easily fixed, along with a few other mods, should be out again tomorrow. There is a picture of the boat in the Elementarry telescoping wing mast folder. Will get some of it sailing this weekend, all going well.
Had to get it up 20m/yds of beach to get it above the high tide mark. Put a fender under the bow, sheeted on the sail, lifted the ww hull and it sailed up the beach. Tempting to strap a trolley under both ends and the ww hull and see how it goes along the beach.
I have booked the garage for next week, will start on the telescoping section.
