How to test the rocker line

To choose a boards suitability for your type of sailing, focus on the tail rocker as this pretty much determines the style of board. 

  1. Flip the board upside down and place a straight edge on the centre-line of the board, with one end aligned with the tail. 
  2. Push down on the straight edge in the middle of the flat section, (approximately the area between the front and back straps).
  3. Now use our easy to remember Windwise ‘Paper, Scissors, Thumb’ to gauge the tail rocker. 

 

Remember, small variations can make a massive difference in the performance of the board.

1

Paper thin

Flat rocker means fast freeride e.g. Severne Fox & Psycho

Push down on the flat section and if the straight edge is still touching the tail or you can just slide a piece of paper under it, the board’s very likely to plane early, be fast and more suited to flatter water. 

If you sail in rough breaking white water, a long flat and minimal tail rocker profile like this can be too fast and hairy.

But if you’re carrying larger sails, looking for great speed e.g. Fox) and want lightening early planing like the Psycho, then this kind of flat is fast!

2

Scissors are for everyone

All-round rocker means freewave e.g. Severne Dyno

If you push down on the flat section and there’s just enough room under the straight edge to slip a pair of scissors, then the board is a good compromise between reasonable early planing, higher wind control and decent manoeuvrability. 

If you sail on both flat water and the sea, using a wide range of sail sizes (particularly sub 6m) then this is a good compromise tail rocker, hence why the Dyno is so versatile.

Thumbs turn

Wave rocker means wave boards e.g. Severne Pyro / Nano / Stone / Mako

Push down on the flat section and if there‘s enough room under the straight edge to slide a finger or thumb, the board is definitely focused towards higher wind control, rough water, tighter turns, wave and much less about early planing.
