Haven’t had the opportunity to try the sail yet but it looks great!
Shallow water? Heavy weed? No problem.
Tribal DELTA
Delta Weed opens up spots you thought were unsailable
Too shallow to sail? Not anymore!
When the water gets brutally shallow or clogged with weed, the Delta Weed keeps you sailing. With radical rake, a wide base and ultra low profile, it skims over sandbanks, weedbeds and tidal flats where other fins stall or get grounded. From GPS speed strips to teaching in knee deep water, Delta Weed opens up spots you thought were unsailable!
Sandbars, tidal estuaries, reef flats, conditions where most fins hit the bottom in the first 50 meters. Add weed on top and sailing seems impossible... Delta Weed was designed to solve exactly that. Its extreme rake and compact depth allow you to ride in less than 30 cm of water while still giving enough lift and control to plane, gybe and enjoy the session. It’s not a Slalom fin. It’s a survival tool, but one that still feels smooth and forgiving!
WHY WE DESIGNED DELTA WEED
Some of the best speed and freeride spots are almost unsailable with regular fins: too shallow, too weedy, too risky. Delta Weed makes these spots accessible.
Whether you’re exploring estuaries, crossing reef flats or teaching beginners in knee deep lagoons, Delta Weed allows you to sail where others pack up and go home.
