Tribal MK1 SLALOM

When milliseconds matter and every knot counts


BUILD FOR SPEED. REFINeD FOR CONTROL.

The Slalom MK1 is Tribal’s premier G10 racing fin, developed through GPS testing, competition feedback and obsessive tuning. Fast, locked-in and brutally efficient. Built to win, yet durable enough for everyday training thanks to full CNC milled G10.


Slalom sailing pushes you and your gear to the limit. You need a fin that delivers maximum performance without compromise. You need lift to accelerate, grip to hold the line and stability to finish the run. The MK1 delivers all of that with explosive drive, exceptional upwind angles and confident gybing grip, even when fully powered.

Whether you’re chasing podiums or personal bests, the MK1 is a race grade weapon that gives you speed and confidence in real conditions.

WHY WE BUILT MK1

Slalom racing demands more than speed alone. You need balance, predictability and control when pushing to the limits. Many fins either spin out when overpowered or feel draggy in lighter winds.


MK1 strikes the balance: fast, stable and forgiving enough to let you focus on the race, not on saving your run. Combine that with G10 durability and price range and it’s clearly the affordable full slalom option as compared to carbon slalom fins.

  • Smooth, controlled acceleration
  • Locked-in stability at higher speeds
  • Reliable grip in chop and gusty winds
  • Durable CNC-shaped G10 construction
  • Performs across a wide wind range (light to overpowered)
