Watercraft vessel with a planing hull

A planing hull comprising:

• a keel region;
• a side portion extending from a bow to a stern, on a respective side of the keel region;
• a V-shaped bottom portion formed by opposing substantially planar surfaces extending from the keel region toward the side portion;
• and
• a chine portion separating the side portion and the V-shaped bottom portion;
• wherein the V-shaped bottom portion includes:
• a pair of opposed water-deflecting surfaces extending rearwardly and upwardly from the keel region and terminating adjacent to the chine portion or the stern, wherein the pair of opposed water-deflecting surfaces faces inwardly towards the keel region and rearwardly towards the stern, and extends downwardly, at an angle relative to a longitudinal vertical plane, from a respective substantially planar surface to a lower longitudinal edge thereof located at a higher level than said keel region;
• and
• a submerged bottom part forming an approximately triangular, laterally rising shape,
• wherein at least a portion of the pair of opposed water-deflecting surfaces extends at a lateral distance outside and substantially parallel to an outer boundary of the submerged bottom part,
• wherein the submerged bottom part includes a pair of opposing substantially planar surfaces extending laterally downward to the keel region, and
• wherein the V-shaped bottom portion includes at least one further water-deflecting surface, wherein the at least one further water-deflecting surface is configured to deflect a lateral water stream downwardly and rearwards at a first planing speed range,
• wherein the pair of opposed water-deflecting surfaces is configured to deflect a lateral water stream downwardly and rearwards at a second planing speed range, and wherein the first planing speed range is lower than the second planing speed range.
