If youve ever been on the Ocean you would know not to even suggest something as silly as a 14 footer car topper with your family LOL.

That being said, those Naden boats are strong as hell. I used them at an outpost camp in Northern Ontario and Im not sure you could split the sucker if you wanted to.

Your best bet is to spend a little more money and buy a bigger inflateable.
Its way more suitable for going on bigger water and its a little easier to transport.
