Infinity Blackfish 14 ft Flat Deck

If you want one of the most proven all-water race shapes in stand up paddleboarding, the Infinity Blackfish 14 ft Flat Deck sits right near the top of the list. This is a board for paddlers who want real race-board speed, but do not want to feel over-gunned the second the water gets messy.

The Blackfish has long had a reputation for being fast, efficient and surprisingly usable across a wide spread of conditions. For 2025, Infinity has kept that familiar Blackfish feel while refining the shape and upgrading the construction, making this version lighter, sharper and even more capable for serious training, racing and fast open-water paddling.

If most of your paddling is on rivers, estuaries, harbours, coastal chop, tidal water or mixed UK conditions, this is the kind of board that makes a lot of sense. It gives you proper glide and acceleration, but with more forgiveness and more all-round versatility than many pure flatwater specialist designs.

Where the Blackfish sits in the Infinity range

The Blackfish is the board for paddlers who want the classic Infinity all-water race feel. It is quick off the line, efficient over distance and far more versatile than many narrower, more specialised race shapes.

If you want the easiest option to live with across a broad mix of conditions, the Blackfish is usually the safest bet. If your priority is more outright pace in the right conditions and you are happy with a more committed race feel, look at the Infinity Whiplash 14 ft Hollow Dugout. If you like the idea of a more modern dugout-style performance board that still covers a lot of bases, the Infinity Everready Team Elite Carbon is well worth a look.

In simple terms, the Blackfish is the one to choose if you want speed without buying a board that only feels happy on one type of water.

Why choose the Infinity Blackfish 14 Flat Deck?

• Fast in real conditions – not just on perfect flat water, but in chop, side wind, upwind legs and mixed open-water paddling too.
• Easy to trust under your feet – the flat deck format and stable outline help you settle quickly and hold your form for longer.
• Quick acceleration – excellent for race starts, buoy turns, short sprints and getting back onto glide.
• Less compromise than many race boards – ideal if you want one premium hard board to cover training, events and fast fitness paddling.
• Premium lightweight build – the Team Elite Carbon construction keeps the board lively, responsive and easier to handle off the water.

Size guide

Your ideal width comes down to your weight, balance, experience and where you paddle most often. As a rule, it is usually better to be on the narrowest size you can paddle confidently for the full session, rather than the narrowest size you can merely stand on.
