Our first boat was not really that good although we got 2nd place. It went 10.4, But this boat is different! We call it slither but really we have to call it ding dong because thats what matt named it. We have no idea how fast it goes because we haven’t tested it yet, it might sink, but you know, thats all part of life. Im pretty sure it will do good but but if it doesn’t, well, who cares.
