The Wave MC design has changed significantly but it is still an on-shore sail. The sail has the same luff design as the Hammer (just 10 cm longer) and similar leech design too. Like last year the sail has 80% re-enforced monofilm with large X-ply monofilm in the main body part. The upper part of the sail uses more standard monofilm, makes it a bit lighter than the Hammer. 

Sailing
The MC wave seems more supple and softer than the Hammer because of the twist of the upper part of the sail. The sail is more powerful and in light or gusty winds you fell more of the sail in your hands. For the ones who like a soft sailing, with a loose attitude they will prefer the MC rather than the Hammer. Powerful without over pulling your arms, the sailing is very stable and therefore feels better for up-wind sailing or to accelerate between waves. The sail is less reactive than the Hammer, softer and easier to sail, you just have to lock it on the deck of the board and go. A very fast, well balance sail for most of the conditions; the sails seemed to be less direct than the Hammer. Saying that, the MC is less precise on the surf, but still fast enough when the conditions are poor (light, gusty winds or/ and rips between wave sets).

Verdict
Does not have the finesse of the Hammer, the MC Wave is more for instable conditions and on-shore winds but it does have a lot of charm from it sailing comfort and end speed. In fact it gives you a sail to enjoy with a lot of backhand power when you want it between set of waves.
