I was going to provide the definition of boat but was beaten to it.
I have a 16 foot canoe that I have had in salt water, Puget Sound, fresh water Lake Washington, Cedar River. I have put $5 in repairs to one of the paddles and enjoyed the heck out of it. The sound was a great learning experience. Most salt water enthusiasts have little patience for a canoe an it is important to stay out of ferry and shipping lanes. The really big boats ALWAYS have the right of way!
I did learn how to make the wind help to get me where I was going.
You have to yield right of way to aircraft, landing or taking off. Who thinks about airplanes while paddling a canoe around a lake?
