GW's latest board game is Dreadfleet: it's all sea battles and evil pirates. I haven't played it yet, but we've painted four sets so far. Here are some shots of a set we did for Scott Hughes in Australia.
What's amazing about these is that GW doesn't even do boats - these are one offs as far as I can tell. The quality beats Spartan Game's Uncharted Seas range quite handily. If GW is using these as a market tester, then Spartan is in for some trouble.
