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 anyones 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. Also available as a bat tail. Good for trying airs and tricks.
