I don't think any one is actually "against" the beam of a 14' cat being in excess of 2.5m, what I think is that a group who are more familiar with the geometry of stability of a 14' "platform" realise the futility of having an "overwidth" 14' cat, and feel that perhaps "stupidity" can be kept out of a class by rules and regulations, (except that rules have never yet stopped stupidity)
