The mutant sludge is a must for any ability of surfer. The versatility of this board in any conditions from 1ft mush to solid dredging barrels. That will put a smile on any ones face. It has a lot of influence from the Lost, 5’5 19’1/4 fish and the Greg Webber fish boards from the 90’s. It feature a Vee double concave through the bottom 5 fin set up with a flyer set back behind the side fins into a swallow tail. This is a great little board for those trying airs and tricks.

  • Fun board

    Posted by Jeremy on 25th Jun 2020

    Super fun board extremely happy with how it went in a variety of conditions. Easy paddler and feels great on rail, in the barrel or pushing it through the lip.

  • The MUTANT SLUDGE 5 7 thruster

    Posted by Rob Duke on 25th Jun 2020

    I find in design the sludge works in many kinds of small to medium waves . At age 50 with 36yrs surfing experience, the sludge turns on a dime. On the slow, testing days the boards design up front helps plane through the flat and dead part of any wave, so anytime the wave opens up and you get on the back foot the refined hip fly swallow takes the wave apart. The sludge is my shortest board Ive ever owned, for the older and experience its perfect for small wave performance .Ive got 2 mates onto the sludge. These 2 lads have had a good long break from surfing and now surfing on the sludge and loving it with minimum effort and lots of fun...cheers Deathless and Sideways
