Kayak Model Notes

Some Kayaks are actually more like a Canoe.   for these type order the Canoe Stabilizer System

Some Brands include:
Native Watercraft 


Which Model Is Best for You?

SF-KS-HD Hydrodynamic Floats  are What Most People Order for a Kayak.  They are Larger and Offer Even Greater Stability.  They are Designed to Travel in the Water, While Paddling. Hydrodynamic Floats are torpedo shaped and lock in place to track alongside the boat thru the water.

SF-KS-EF Eathafoam Floats Work Well on Kayaks, but if You Place Them Aft the Cockpit, Some Find it Challenging to Reach and Lower  Them Behind Your Back.  Since the Eathafoam Floats are on a Center Pivot, They are not Designed to be in the Water While You Travel.  Keep Them Raised out of the Water and if You Start to Tip, They Will Prevent You From Tipping Over.  When you Arrive at a Location Where You Want Extra Stability, A Quick Turn of the Knob Lowers Them into Contact with the Water.

Both Models  Attach to Any Point Stem To Stern on Your Kayak   Many  Attach Them  Behind or Aft of  the Cockpit  as a Convenient Spot, However, You  Have the Flexibility of Putting Them at  any Position You May Prefer.  We Suggest you Try A "Dry Run" before Permanently  Mounting the Hardware  and Test That Your Paddle Stroke Won't Be Affected By the Float Position.
