The K4 Rocket Rear Wave windsurfing fins are plastic molded fin for onshore wave conditions or fast bump n' jump riding. The swept straight profile translated to a speedy fin great for outrunning a close out onshore wave or sending big jumps on the river. Despite being plastic, these K4s are super stiff, durable, and fast. These are great fins for any sailors looking for a performance fin at a lower price point than fiberglass or G10.
The Rocket wave fin. Almost like having slalom fins in your wave board! Lift, drive and speed for onshore conditions. Great for early planing and jumping. Also surprised us with their DTL performance but you’ll need to use your rails for powerful turns as they don’t have the same grip’n’whip in big cut backs and snaps as with the flexier fins.
