Patent attributes
A multihull watercraft has at least three hulls extending longitudinally along the watercraft. The hulls at least partly define a port side tunnel and a starboard side tunnel therebetween. A port deflection device is configured to engage water in response to the watercraft leaning toward the port side when turning. The port deflection device is laterally aligned with the port side tunnel. A starboard deflection device is configured to engage water in response to the watercraft leaning toward the starboard side when turning. The starboard deflection device is laterally aligned with the starboard side tunnel. Each of the deflection devices includes an angled surface extending downwardly and rearwardly from an upper tunnel surface of a corresponding one of the tunnels. The angled surface is positioned to remain above a water line when the multihull watercraft is at rest on water.
