I have a Beneteau Oceanis 300 that needs the standing rigging replaced. I was wondering if there's a data sheet somewhere that gives me (with confidence) the sizes and lengths of eacj replacement wire for my boat. Most web sites I've visited suggest removing all rigging myself, taking the bag of wires to a rigging specialist and then having replacements made up from the old templates but it would be so much easier if I could simply get the dimensions. Maybe I'm being naive and there's enough variation in these boats to make it impossible to provide a single set of figures. Any help much appreciated.
