Unfortunately, rules cannot be interpreted on principles and ideas of what the class is “supposed” to be like. We grapple with that every day over here in the States as everyone and their brother tries to define what our “founding fathers” meant - or intended ! :mad:
Once the class goes down the road as a development class, whether 12 inches long, 36 inches, 48, 8 feet, 20 feet or 40 feet - development means just that - you are allowed to do anyhting NOT prohibited. Even one designs try this and find out folks can identify loopholes quicker than they can be plugged. I am not an ODOM racer, but discussion came up about having a smaller rig for stronger winds. The class rules (one design) allow only one rig. The rules prescribe the mainsail luff is 52" (as I recall) but nothing in the rule prevents a sailor from reefing his sail (not the stiff mylar ones of course - but soft rip-stop nylon is not mandated) to whatever sail area he wants so he can race in many wind conditions with optimum sail area. They will probably make a rules change in the future to catch that one, as the "intent’ was to have all boats identical as possible regarding rig/sail area.
To name a specific winch is hard - since the Laser Class specified a winch - but have had to change rules to allow the HiTech replacement winch now that the old model is no longer made. Anthor problem with "naming a product if you don’t control it’s manufacturer.
Basically, I am saying when you elect to enter a class that is developmental, it is suggested the rules be read and understood so you know what you are getting yourself into. In the case of the Footy, the basic idea was to create a boat at a specific length with few other considerations. As you can see, the original balsa slab side fFooty has given way to ultra-high tech carbon fiber built in a mould. Was this what the originators of the class wanted? Hard to tell - but it is where it headed when it was designated as development. So to play, one must pay.
Of course, if you do not race, it doesn’t matter - right?
