I would have fresh water craft like skips and rafts, canoes and logs. Hazards may include alligators, log jams, plant growth, carnivorous fish, and various fauna. I would have better access to sea ships and more of them. They can dock in as a fleet of ships to alleviate congestion. Id like to see water monsters that can attack but do no permanent damage to craft, although you should be able to die. A ripple in the water would send shivers down one's spine. These monsters may include kraken tentacles, pirates, sharks, whales, flying fish, or even merlew. Make the seas a viable and desired lifestyle. It's hard to be a pirate without a boat!
