For the Coos Bay campaign battle I knew I wanted to have the posses fight each other from the back of Swimmers. For those that aren’t familiar, traditional boats and ferries aren’t used in Dinosaur Cowboys. Instead in the spirit of the theme giant ferries and ship decks are strapped to the back of various dinosaurs, such as a ferry on a Thalassomedon or Mosasaurus, whereas a smaller sloop would be on a Nothosaurus.
Soooo you kind of end up with a ship deck, but in your imagination it’s on the back of a dinosaur. In terms of game mechanics that makes the boat MUCH more maneuverable since you can go backwards without momentum, cross small islands (since the dino can clamber across), etc.

In terms of the rules I mapped out decks for the Sloop and Skiff (which can be launched from the Sloop). The actual passengers ferries would be much larger. You can see the layout of these to the right, or in the rules themselves.
Otherwise the rules provide a framework for moving the ship, using various stations on board (like going “Below Decks” to heal, firing Swivel Guns and Cannons, etc.). There are also rules for boarding via boarding planks or grappling hooks. Also for swimming in deep water, and everything else necessary to add boats to a standard game of Dinosaur Cowboys.
In terms of balance and tweaks, we’ve only played the rules once, but they seemed to work well. The biggest complaint was that there wasn’t much incentive to fire a Cannon. So I’d consider tweaking those to Reload None (instead of Auto), giving it a bigger arc, maybe a different damage scheme (like 1D12 Attacks, D6 Damage), etc.

Anyway the rules are fairly one off so I don’t think I’ll revisit them again. I’ve been loosely brainstorming a new naval game in the back of my mind so this was somewhat an outlet for that. Plus it’s fun to have a unique battle every now and then!
