Water bases

I know that Trumpeter sometimes includes them with some of their larger ships, like aircraft carriers, but I'm not aware of any company that makes generic water bases.

I've always made my own - acrylic paints and acrylic gel medium and you're good to go.

Thanks, I'll try that this moening.  I guess I didn't give enough description.

I just did a google search for "bases for waterline ship models" and came up with a lot of results.  Didn't look at any links, so don't know if they are what they are what you are looking for, but that is a good starting point.
