Because I'm in the process of building an F16 to my own design, I thought I'd do a bit of research into the design of the centreboard. I'd read in these forums of a rule limiting cb cant to only 6 degrees, which I'm happy to abide by, but couldn't for the life of me find it in the rules.
I've consequently discovered it in the definitions section, but the way I interpret it, the definition doesn't limit the cant, it just states that any centreboard like item that is canted at more than 6 degrees isn't a centreboard...so it must be something else. I'll call it a widget! Widgets aren't banned in the rules. (I'm being silly)
If F16's don't want more than 6 degrees centreboard cant for the class, it may be wise to move this definition to the actual rules, and worded something like "...centreboards shall not be canted more than 6 degrees from 'vertical'...", whatever vertical may be. I'm sure this is the intention of the definition, the intention just needs to be reinforced.
