Can you help me?
Is there any difference between "in a boat" and "on a boat"?
It depends on the size of a boat.
In a row boat, a canoe, a kayak, a speed boat.
On a yacht, a cruise ship, a naval vessel.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
