Thresher

''"Known as the "caddy" of the H.T.R.A. lineup, Thresher is the easiest boat to control. Big and heavy, the boat is well balanced and is easy to steer. Although it has a fairly slow Mighty Hull activation time, Thresher's secret weapon is its ability to knock opponents around by using its heavy frame."
