A method of wake surfing utilizes a marine vessel having a first propulsion device and a second propulsion device that produce thrust having thrust axes that are offset from one another or not parallel. A first propulsion device may have a thrust axis that is controlled to a first thrust offset angle with respect to the second thrust axis.

The first thrust axis may be along a horizontal and / or vertical plane with respect to second thrust axis. One or more deflectors may be coupled with the boat to aid in formation of the wake surfing wake. A controller may control the thrust axis and / or the amount of thrust produced by the propulsion devices, independently.
