I don't remember his forum name. He was around here in beta. He made a few posts in a single Ten Forward thread with one of his fan ship designs. The response was incredible. So incredible, in fact, that his post was quickly buried in a few dozen pages and lost except to those who saw it and were following the thread because of it.
I managed to track down his Deviant Art account again. I looked through the contestants and I don't see anything resembling his work (and if there is, someone should verify that it's not someone stealing it) or anything nearing the quality and love that goes into his designs.
Here is a front and side view of the ship he was showing off in beta. Maybe I'm just missing it and he has submitted it, because the last time I saw it, it had it's own name and now it's called the Enterprise-J in the pics.
He has some other great ones in his gallery as well.
I'm hoping he's still around and has submitted at least one of his designs as they look very canon while still looking futuristic. If not he needs to be alerted to the contest.
Well the link I put here didn't stick to the specific ship. Oh well, two designs on there that I thought where interesting enough to be the F. A few that I would not and one I deplore entirely because it does not even look like the Federation.
