The RS900 - 'our' fantasy dinghy!

Originally posted by winging it I looked at the asbo website again last night.  There were some pics of some experienced sailors presumably sailing the finished version, and it still didn't inspire me as much as a 5oh does.  The proof of the pudding, of course, is in the eating: I am still awaiting my invite  oh, and I'm afraid this pic of yellow wellied old beardies was the only one I could copy across... Clearly the photographer caught them just before they got into their morris traveller and trundled home for a nice cup of tea and a round of golf...

"cup of tea" ?

All sorts of loads change in quite a complicated way if you have a two string/caps rig against a single string/spreaders rig. The mast is supported quite differently. I'd normally expect the total loads to increase because the extra trapeze unloads the windward shroud and that has to be compensated somehow.

When I changed my Cherub from single string/single shroud rig to caps/checks/shrouds I used lower shroud tension but alongside the shrouds pretty near the same load again in the check stays, so the total loads were much greater - to such an extent that I had to beef up the internal framing because the boat was bending.

Don't think loads are much an issue, since rig tensions are not that much higher than the standard 29er.

Actually, the rig is now completely different to the 59er, but this has been the case for quite some time now. The spinnaker is flatter and she carries another 1sqm of main plus jib. The mast is stronger, in order to better support a twin wire crew and a square cut top main. PLus the alu rudder gantry and gunwhale extensions.

Just a note, the last time I really had anything to do with the XX was at the Garda worlds in '09, so all may have changed since then!
