This is another option I was thinking of. Attach a small outboard or even an electric trolling motor. But, not easy to find a canoe for 4....I have a square stern canoe with an outboard but its a load, portabote probably the best option.
It all depends on what you plan to do with it. I used to own one for white water river rafting but it is pretty miserable on still water.
Trying to avoid a boat trailer. If an inflatable, flat back canoe or aluminum fishing boat, I would def have a motor.I used to dive off of an inflatable FC470 (hence my user name) which is a very large inflatable boat just over 15 ft. They're the popular inflatables boats for SF units. It was a big mother for a small boat and hard to deflate and store so I ended up selling it. I did trailer it down to mex a few times for some spear fishing and it was awesome because it's lightweight when towing and easily launchable. I slayed a lot of fish and got a lot of lobster off that boat.
On a few other occasions I went to mex with a friend who had a 6 foot inflatable zodiac with a 5hp I think, still large but manageable when stored. Like others have said, there are better options but if you have a camp trailer where you can store everything it makes it easier. All the gear associated with boats also takes up a lot of vehicle space and storage space.
I've also fished and dived off of a kayak which was easier in some ways and harder in others.
An inflatable will work for you if you have the space to store it and the capability to inflate/deflate and carry the motor- they don't track well with paddles. There are foldable trailer options from harbor freight that you can use, my father in law had one for his tender for a year but then got over it and sold it.
I'm sure there are much better options, that is just my experience. I've been out of the dive scene for the last 8 years so am not completely up to date on the new products.
No clue. I just googled truck hauling boat.
