The New Britannian Ship was just announced today, being released in the next publish. The ship will have 2 more cannons. Holds 28,000 stones. Can put a forge, soulforge, loom, spinning wheel...and I think a parrot on it.
To get one you will need to contribute to the Fisherman in the Brit Library, 10 Million Points worth of goods. Fish Steaks are .25 points, Whole Fish are 1 Point, Fishing Poles 2 points, and Crabs / Lobsters are 10 points each. (Thanks C2 you helped make it a little easier for us)

At 200 per hour... It would take you just short of exactly 7 months of 24/7 Crabbing/Lobstering to get enough points. (Math done by MeWonUO)
So, we need to fine tune the donaters to donate crabs to the Fisherman at the Brit Library. Actually, that might be a bad idea as they will be out looking for Scripters at the Library now. Just deed them up once or twice a week and donate them!
I heard also, that there will be a limited number of Britannian Boats for Sale on UO Game Codes (but, who wants to spend more real money on an item you can earn).
