I've aired my comments on model contests several times in the Forum, and I don't imagine anybody wants me to do so again. Briefly - I don't believe in model competitions. But to each his/her own; if somebody else wants to enter a competition it's not for me to talk him/her out of it.
Enemeink's comment reminded me of my days (1980-1983) as curator in charge of ship models at the Mariners' Museum. One of my more frustrating duties was to come up with a set of rules for the museum's next ship model contest. (The first one had been held just before I got there, and it was planned as a once-every-five-years event. That MM competition had quite a reputation until, if I remember right, 1995, after which one of my successors decided to discontinue it.) I sent out a form to all the people who'd entered the 1980 contest, asking them for suggestions. Bad idea. The notion of breaking the competition into subject categories was obvious. (There had been no such categories in the 1980 contest, largely because the museum had expected about a dozen entries. More than a hundred showed up.) If I'd followed every suggestion I got on those forms, one of my successors would have been in the position of writing a letter reading: "Congratulations! You've won the second place award for a semi-scratchbuilt, full-hull, plank-on-frame, unpainted, rigged model of a nineteenth-century sailing ship more than 100 feet long, built to a scale larger than 1/16"=1', with hand tools, by an amateur - outside a bottle."
We eventually settled on three subject categories: sailing ships, powered ships, and small craft, further divided into scratchbuilt, semi-scratchbuilt, and kit (modified or unmodified) models, with a special division for junior modelers. (To my knowledge, nobody ever entered the junior division.There's a sad commentary.) I think the museum retained those categories till the contest shut down. There's been talk of reviving the idea at some other institution. I believe the Navy Museum in DC has expressed interest, but to my knowledge nothing's been done about it yet. If that competition does get revived, it will have to do it without me.
I won't say I'll never enter another model contest; if I hear about one in which the grand prize is a new Ferrari and the runner-up gets a Chevy Corvette, I just may show up. Otherwise, though, no more model contests for me - and I'll never judge another one.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
