The most convex of the wave sails in this test with a large leech opening at the head, the Transwave 5.3 was tested this year with a 4m mast. It's made of reinforced monofilm with the weave more widely spaced in the window section and a mast panel made of Dacron.

ON THE WATER: The Transwave has a deep and supple profile and has become a benchmark sail thank to its unlimited power. It tugs hard on the hand before taking off for early planing in light conditions, when there is current on the spot or onshore: more comfortable than average in the chop. It is aimed primarily at those that are in shape, powerful riders that like to keep on planing and change direction quickly on the spot. It moves upwind easily. This relatively advanced XXL power will help to prevent you being overwhelmed on the back hand in strong winds, but be aware that it will tire out the lighter and average weight riders quickly. Perfect for getting up to speed in waves that lack power, the Transwave generates maximum speed in the preparation for the jump. It has the advantage that it can be used in very light winds, with wide boards that need a good push to start planing without becoming overpowered. For pure surfing, it remains more physically demanding than many five batten rivals for the average body weight. So, the Transwave is better suited to beefy builds that will enjoy its lightness of touch under the back hand and good manoeuvrability in the surf.

SUMMARY: A reference board for the heavier rider and those looking for maximum juice and power in the waves, while carrying the smallest possible surface area. Its very stable behaviour means it is very efficient in messy conditions but also for executing Bump & Jump.

+: Price, XXL power, stable profile, good performance, for heavy riders, discret back hand.
- : A little heavier than the average, more cumbersome for light riders.
