Fat2 Blade

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.

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 a shorter oar length. 5–6 cm shorter than a standard Smoothie2 is the average recommended adjustment.
