Boat with reconfigurable running surface for wake adjustment

A watersports boat comprising:

• a hull having an underside extending from a forward bow to an aft transom along a longitudinal centerline, the underside defining a running surface that contacts water when the hull moves therein, the running surface including a planing mode trailing edge and a pre-planing mode trailing edge;
• an aft running surface section of the hull including port and starboard recesses formed in opposed corners of the aft running surface section and spaced outboard the centerline, each of the recesses having a substantially continuous upper surface extending from a respective step at a forward end thereof aft to a respective aft edge thereof;
• and
• port and starboard aft hull side surfaces tapering inboard and downwardly toward the centerline moving aft, the port side aft hull side surface sharing a common boundary line with the upper surface of the port recess, the starboard aft hull side surface sharing a common boundary line with the upper surface of the starboard recess;
• wherein:
• the steps form the planing mode trailing edge where water disengages from the aft corners of the aft running surface section when the boat travels in planing mode;
• the aft edge of the recesses form the pre-planing mode trailing edge where water disengages from the aft corners of the aft running surface section when the boat travels in pre-planing mode;
• and
• no repositionable surface is located below the substantially continuous upper surface of either the port or starboard recess.
