The first OD cat classes in England (Shearwater) and Australia (Yvonne) are both still alive - proof that ODs do NOT die as you claimed.
Kieth, bummer about your tramp. We had a similar problem with ours, in a class that HAS got multiple suppliers. We haven't really worried about it.....compared to the cost of updating to the new sails that competing sailmakers have brought out it's a minor problem.
I'm NOT having attacking ODs, or loose ODs, or development classes, they're all fantastic and all offer vital things to our sport. All I was doing is replying to a claim that ODs always die when they clearly do not, as is proven by the fact that the very first ones are still around.
Hiyas,
I don't think the OD's are doomed at all. The whole concept is evolving though. Not many classes that have lasted the distance are *exactly* the same as origional. H16's have changed, H14's change, even the Yvonne that you mentioned have changed. The boat was designed in the mid 50's and stayed virtually the same till the rig was changed in the early 90's and more recently the origional spi has changed to a huge assemetric (sp?). They are good to sail - like sitting in a big comfy arm chair
