Abstract
A floatation device may include a bow section and a tail section pivotally connected to the bow section by a kingpin assembly. The kingpin assembly may be configured to include a positive kingpin inclination angle or a negative inclination angle that determine the yaw direction of the floatation device. A user may control the tilt or roll of the floatation device to offset a yaw direction and maintain a straight line tracking course.
Claims6
A floatation device comprising:
- a) an elongated bow section having a longitudinal center axis, said bow section including a forward end and a rear end;
- b) a tail section pivotally connected to said rear end of said bow section, said tail section including a rudder extending downward from a bottom surface of said tail section;
- c) a kingpin assembly coupling said tail section to said bow section;
- and
- d) said rear end of said bow section defining angularly extending surfaces, said surfaces extending from proximate said longitudinal center axis in opposite directions toward opposite side edges of said bow section.

A method of controlling tilt yaw of a floatation device, comprising:
- a) said floatation device including a bow section and a tail section, and wherein said floatation device includes a longitudinal center axis;
- b) providing a kingpin assembly pivotally connecting said tail section to a rear end of said bow section;
- c) applying a downward force on said bow section at a point laterally offset from said longitudinal axis to effect tilt or roll of said bow section causing said floatation device to steer in a first tracking direction;
- d) simultaneously paddling along a side of said bow section proximate to said point laterally offset from said longitudinal axis, and thereby causing said floatation device to steer in a second tracking direction opposing said first tracking direction to maintain a relatively straight line tracking course.
