You will definitely notice the speed difference, but here is where the real benefit comes into play;
You get the same fast speed with a lower cadence on the peddles. The resistance needed to peddle is only slightly more, but the fins have a tunable ferrule screw on each sail mast so you can set them to suit you needs.
You can peddle like your in 10th gear, or 5th gear depending on how you tune the fins. If you have strong legs you can set the fins stiff and use fewer RPM's to achieve the same speed.
Its an immediate upgrade, and a must have in open ocean.
