Karma foils at last

A test on Wednesday revealed continued foil control / linkage issues.
I rejigged the main foil incidnece on Thursday and greatly improved the linkages adding a tiny model yacht rigging screw for fine adjustments.
Saturdays pre race test proved it worthwhile and the boat flew straight off. OK but low upwind but high, fast and stable downwind: looking good. As this was as much work as the boat had done it was also a good test of various experimental components two of which were found wanting.
First the forward rakes diamonds spreaders broke proving that they really are doing something and also that the mast will not break without them.
Then while riding high on the opposite tack towards home, the tiny half rudder box shattered.
Repairs will be simple but I think I am running out of time for the Easter State champs. I would rather sail my properly sorted boat than spend the weekend breaking and repairing.
And to reinforce that opinion, I made the beach in time to pack up Karma and rig Tiger on a Chain, make the race start and sail as well as I ever have, finishing third to Dave and Steve in the last heat of our club champs. I think the old boat was telling me that it is not finished with me yet.

Karma sails

I launched Karma yesterday afternoon in a light easterly scratching to make 10kts. A short sail but at least nothing broke. No unusual noises either. I had some unforseen linkage issues and it did not foil so I still have some sorting to do. As well I tore a pocket on the tramp so its off again for some adjustments. Should get another test later in the week when I will get some good photos.

So far so good. It certainly goes better than std in sub foiling pressure downwind, with the unstayed rig going fully out. Full width tramp is comfortable, Cut down tiger hull has enough volume in the right places.

Karma with wings


Some effort being made to get Karma finished for a week's time.

Wings are on. Very light. Mast, boom, tramp and rudder box to finish.
