Please note that the Pathe Pictorial labelled 1956 is in fact 1955. You can see me in it!

We look forward to seeing pictures of her sailing. Chippendale did build good boats.

The current PY is 1094. This applies to all boats. Our Class Association agrees that 1094 is correct for modern boats. For your Design 8 they suggest 1104 as a PY. Your club may well insist on using a PY of 1094. In my experience you may well find that in lighter winds you will do all right with 1094. Enjoy your sailing.

As I understand it, the wire from the bottom of the shrouds to the mast foot is to transfer the vertical load in the shroud to the bottom of the mast so that the mast compression balances the shroud tension. The space frame deals with the horizontal forces. I would expect that (hidden in the forward buoyancy tank) there is also a wire from the forestay foot to the mast foot to do a similar job. The end result is that most of the rigging loads do not go through the hull shell.

The cigar shaped "thingy" with threaded bolts is a turnbuckle. The threaded bolts have opposite handed threads. Rotating the barrel (using a rod through the hole in the middle of the barrel) while not rotating the bolts will lengthen or shorten the wire. You need the lock nuts to stop the turnbuckle coming undone.

When the jib is hoisted and the shrouds are tensioned you want the load on the hull shell to be small. I am not sure exactly how this is measured.

I learnt to sail by crewing in her and other boats
