I own the Hyside Paddle Cat....it is clearly a copy of the shredder.
Was on Brown's when 3 of the orginal shredders came by. We all took out at stonebridge.
The boats are VERY similar. The shredder tubes are more pointed, the Hyside has blunt caps.
Length - with - tube I could not visually notice any signifcant difference.
I have found the hyside to like the shredder roll small and light. Easy for one person to carry, could be checked on a airliner no problem.
I bought mine from Peter who is a guide up in eagle this spring.
I am told he still has one left.
