Hey there, calling all sailor and boating people!

I am refining my novel, adding details and revising stuff to make the world (it's a fantasy, sort of medieval) more plausible.

Here are my questions:

1. What kind of harness or yoke would work for a manatee-like mammal to pull a small boat on a fresh-water lake?

2. How to steer this kind of craft?

3. Would a design with high sides and up-curved prow and stern work, do you think?

4. What would you recommend for docking procedures and an emergency sail system should the creature be injured, wounded or weather not cooperate?

Thanks, all you water-experts! I have sailed a grand total of two times and absolutely loved it...but canoes are NOT my thing (they tend to go only in circles for me)
