Tyson isn’t exactly delighted by any mode of transports, but he finds boats to be agreeable enough.
Whenever possible, Tyson would prefer to keep his feet on dry land and move under his own power, but he isn’t afraid of boats in any capacity and accepts that they’re safe enough.
Unlike planes, Tyson has no negative memories surrounding boats. In fact, Tyson has a lot of pleasant memories of time spent with Jethro and his family on boats. Even with Jethro’s adoration of coral factored in.
