Wheels advance their contact point in unison with their rolling surface. Cycling a track around turnarounds extends the friction-free point. Add flotation and watercraft friction can be reduced indefinitely.

But wave and turbulent resistance are bigger factors than friction. The reel boat addresses those factors by slowing relative motion at the hydrodynamic interface.

Can the wheel work its magic on the other 2/3 of the earth? Let's find out!
