Tugboat

Jaunt pack asset: a tug on its own little pond that rides the waves. Its bob, pitch and roll come from the wave height under its bow, stern and sides. Tyre fenders, a lifebuoy, a wheel at the helm behind glass, and a funnel that puffs. Raymarched in WebGL with a real ground shadow. Six palettes or your own colors; any number share one WebGL context.
