I think I've over-read and over-thought this and confused myself!
I need to do a carved ship for 25-30 people.

Which would be best?
12x12x2 cut in half and stacked for a 6" wide ship (if so, will 3 layers be enough?)
10X14x2 cut in half and stacked for a 5" wide ship (again, number of layers?)
I don't want to use ovals or the rounds sut and stacked.

I've also never done the WASC before, but I'm thinking choc wasc for this, any thoughts?

I don't want to overdo and make too much nor short-change it either (it will be a donation)...

Thank you all in advance!

I'm not sure about the servings either. The height won't really effect the servings, since you'll still slice a 1" thick slice per serving. Unless of course you're using a board between layer 2 and 3, then they can be unstacked and sliced, giving you twice as many. A 6" round serves 12. But then how do you carve?

I'm obviously no help. Easy to over think this one. Probably a very good explanation out there, somewhere.

So here's a bump.
