i am sure this question has been asked many times on this website but allow me to run it by once more.its all about the mainsheet setup on the oday 22 built in the mid 70s. you know what i mean. its the deal where the sheets are shackled onto a triangular plate on the backstay and then runs on to the end of the boom.is this safe? DOES ANYONE HAVE any alternative configuration I might use or has this system worked out okay for you? THANKS A LOT

Backstay mounted sheet

Art - There are a lot of boats out there with a sheeting arrangement like yours and if everything is in good shape there tend not to be problems with it. The general issue is that pulling perpendicularly to the stay changes rig tune and if things are loose can really alter geometry. On the other hand boats are built with backstay adjusters to allow you to tighten the stay to windward, the condition you are likely to exert the greatest force during. If things are in poorer shape, the mainsheet rig could precipitate a rig failure but there would have to be other things going on there too. In terms of change, you can install a travler across the aftermost part of the cockpit. You would see substantial performance gains, especially to weather or in big wind, but as a safety issue its probably moot. If things were bad enough the stock system would take the rig down its going to come down anyway - with a hard jibe or similar stress. Justin - O'day Owners' Web

Mast connections

I have had some experience of failure on an Oday 23 with the same type of riging. It works fine if everything else is right. Be sure to check all points of connection. a failure of a cotter key at the wrong time could lose your mast. On my own 23 I've never had a problem
