SONIC Pro Carbon SUP Race Fin
Maximum Speed & Maneuverability for Elite Racers
SUP Race Fin – The SONIC SUP race fin is designed for raw speed, enhanced flow and ultimate control. This race fin will help you connect bumps while downwinding, sprint faster and surf into the finish with speed and style. The Sonic is best suited for high cadence advanced to elite professional paddlers. Built in ultralight pro carbon construction this is the lightest race fin available.
The Sonic Sup Race fin is the smallest and loosest feeling sup race fin we make, it frees up the tail of raceboards and encourages a dynamic, flowing and fast racing style. The combination of a race proven foil and progressive rake enable experienced riders take advantage of even the smallest of bumps which the ocean provides. This fast and loose feeling is ideal for elite riders with a high cadence who are in tune with ocean chop and currents. On flat water the Sonic is blisteringly fast, in downwind conditions it enables you to flow through a series of swells and in surf the ability to take off late and carve on the wave face opens up new possibilities during beach races like the Pacific Paddles Games.
By design this is not a fin for everyone! Hopefully by reading the above comments you will be either “Yes, I definitely want the Sonic.” or “That is not for me.” Experienced paddlers are those most likely to benefit from the Sonic’s performance characteristics. Riders who like a free and fast feeling and are confident on their boards will experience benefits. If you like grinding out long distances with a low cadence then the Tiger or Maliko will be more suitable. If you have a higher cadence and want to enhance your agility then the Sonic is for you. If you like to surf your raceboard then the Sonic is certainly the choice. If you are an experienced downwinder then the Sonic will help you improve further. The Sonic has a 45 degree initial angle on the leading edge and progressively more curve, hence it is great at shedding weeds and trash, given it is short at only 18cm then those in shallow waters will also like this fin option. If you are planning to attend a race like PPG then then make sure that you have a Sonic in your fin quiver and get training hard (we’ll see you there).
When investing in a fin upgrade, you need to make sure you have the correct fit for your board. Unfortunately, board companies have so far not agreed on the preferred standard for fin boxes.
What makes it more confusing is that to the untrained eye, both fin box systems look almost identical. Luckily we have this area covered and the details below will ensure that you get the correct fin for your board.
US STANDARD Base
Fits Starboard, JP-Australia, Fanatic, Mistral, RRD and most production brands with an origin in windsurfing. This is the same fin box that’s found on many windsurfing boards and is wider and deeper, with the pin set further from the deck of the board. The base is 9.2mm thick.
US SURF Base / Longboard Base / Bahne Box
This is the same box that is standard in many surf longboards. It is a narrower and shallower base as used by SIC, Infinity, 404, Naish, Flying Fish and many more. Narrower and shallower than the US base, these boxes have the pin set closer to the deck of the board. The base is 9.0mm thick.
