Seabase fits the new F3 Fin System as standard in all its custom boards, including Quiver®.  Standard fit on our E-Series and Seaflex™ range. 

 
Why? Its the strongest most adaptable fin system we have ever used. Seabase established both Futures and FCS in Europe - our choice is now F3, and it should be yours. F3 takes all Futures Fins, FCS Fins and the first fully adjustable F3 fins in the world! Be adaptable, give yourself an edge and ask for F3 in your next board.

The F3 Fin System; 3 years in testing and refining, and represents the third generation (hence F3) of removable box systems, has been granted International patents in all the major surfing countries.

Tough, very good looking and uniquely takes not only its own F3 fins, but is fully compatible with all Futures and FCS Fin Sets, making it totally universal and the perfect travel setup. You will find fins for this system everywhere in the world. 

  Features: 
  • Immensely tough - without a doubt the strongest removable box system yet devised. Foolproof, functional and totally practical design.
  • Multifunctional – takes Futures, FCS and the systems own F3 adjustable fin systems. No problem deciding which favourite fins to use - it takes both. Adds resale to your board.
  • Great engineered looking boxes – clean, neat, effective and highly saleable feature for all boards.
  • Unique patented headed grub screws give limited travel and eliminates or dramatically reduces excessive torque causing slot distortion and stripped threads, the major cause of problems with similar systems.
  • Reduces or eliminates the problem of broken bases and fins caused by excess force on the tabs, and prevents warped fin placement caused by differing screw pressures. The fins are always straight and true. 
  • F3 boxes enable the use of the adjustable F3 fin systems. (Available end 2009). Up to 30mm of travel for each and all F3 fins if required, unlike the fixed Futures or FCS fins. Tune your surfing!
  • Double screws increase security, yet can be used with just one screw if necessary.
  • Holds Futures and FCS firmly, especially in rear box, with little or no excess flex. 
  • Huge torsion strength relates to power from box to fins with little loss.
  • Unique engineered positive reinforcements for the screw threads reduce breakage around the entry point.
  • Accurate and correct off-sets for both Futures and FCS fins. Uniquely changeable insertable offsets (from 2º to 9º) for extra offsets with tailored inserts for quads, fish etc (Available late 2010). You can play with more splayed fins without a huge outlay or having to buy a new board. 
  • Standard extra replacement inserts available in the autumn. Keep a set with your fins for quick and easy interchangeability.
  • Separate quad systems not required. Takes all Futures and FCS quad systems.
  • Prepared for a whole new range of high performance fin systems from Curtis Hesselgrave and other designers world-wide based on adjustable F3 concept.
  • Open system – you can make your own fins or have them made to fit. Simply, quickly and effectively.
