So I was testing some stuff out to try and do a no boat run ie. Swim from island to island. I found out an exploit. when the cart is empty and in the water you can jump into it and start walking in it (walk towards handles) and the cart moves forward in the water, you change direction aswell by just walking more left and right. You can effectively walk on a cart all across the ocean, island to island. Not what I wanted, it's just a bit too much of an exploit for me to count it towards a no boat run cause I want to utilize swim skill, basically it's just a foot powered boat. If you can make a cart you can make a boat but interesting nonetheless. Wonder if the devs know you can do this with the cart.
