The Gremlin is going to give you the same feel as the Ghost and Phantom models except in a chunkier, shorter shape for smaller waves. It's a further step down from the Phantom model and is predominantly used as a grovel board. It generates speed easily, offers plenty of paddle power but still has enough tail rocker for whipping through turns and milking every wave for what it's worth.
The Gremlin will get you pumped to surf on smaller days or fatter, fuller waves. It will maintain speed over fatter sections and offer extra paddle power. Ride with roughly 2-3 litres more than your standard shortboard.
