Fat2 Smoothie Vortex Edge

The Fat2 blade is our most recent design. Based on everything we know about how blades move through the water, it offers the greatest potential for increasing boat speed.

Blade Characteristics

Greatest taper at tip of blade

Largest surface area for Vortex "sticky spoon" action

Curvature to aid in depth control

Loading Profile

Loading profile refers to the relative loading at different phases as the blade progresses through the drive. The Fat2 blade's Loading Profile is as follows:

• Sharp grip of the water at entry
• Heavy load in first 1/3 of drive
• Light load through last 1/3 of drive
• 'Stiff' shaft feel

How the Fat2 Blade Propels the Boat

• The Fat2 offers the most pronounced emphasis on the first and second phases of the drive.
• The Fat2 puts the least emphasis on the last phase of the drive to minimize losses that result from the backward blade movement inherent to that phase of the stroke.
• The Fat2 slips less in the water, thus losing less of the work done at the handle.

Due to its increased efficiency in the water, the Fat2 requires different rigging than our other blade designs.
