Mostly, I just need a plate with a raised bit in the middle to keep my desk dry. (or maybe just a plate? what makes a plate a teaboat?) Something in celedon? I'd also love one of those Sea Dyke promotional plates.... or a copy of one I don't really care my desk is wet. (not really)
I have found some modern tea boats some are lovely dragoteahouse always reliable for quality mass produced goods has a few:

I already own this one, it's functional, but no longer feels right with my teaware.

For the price it's a nice solution.
Then there are the modern creations

You know, the easy way out is to just use a plate. Nothing wrong with that. But what fun is it being easy?
What is floating your boat?
