Pull-Behind Watercraft Accessory Device with Stabilizer Fin

A stabilizer fin for a pull behind floatable storage device, the stabilizer fin comprising:

• a pivotable fin;
• a mounting plate for mounting to a rear edge of the pull behind floatable storage device;
• a pivot pin for passing through a pair of mounting holes in said mounting plate and for passing through a hole in said pivotable fin for mounting said pivotable fin to said mounting plate;
• said pivotable fin comprises a counterweight in a lower section of said pivotable fin;
• said pivotable fin pivotable from an up position to a down position, wherein said pivotable fin is biased to said down position;
• said pivotable fin pivots to said up position when said pivotable fin contacts an obstruction and the biasing is overcome;
• and
• said pivotable fin pivots to said down position when said pivotable fin is free from the obstruction and the biasing is not overcome.

A method to reduce drag of a pull behind floatation device attached to a watercraft, the method comprising:

• attaching a stabilizer fin rudder system at a rear portion of the pull behind floatation device;
• said stabilizer fin rudder system having a mounting plate attached to said rear portion of the pull behind floatation device, wherein said mounting plate includes a rivet and a pair of eye bolts for securing said mounting plate to the pull behind floatation device;
• mounting a fin in a notch of said mounting plate using a selectively removable pivot pin;
• aligning said fin with a centerline of the pull behind floatation device;
• said mounted fin pivots freely up and down in vertical directions in a plane running vertically through said centerline;
• and
• said mounted fin is biased in a vertical down position.
