Wave MC 5.0 

Planchemag Magazine

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.

Other Sizes: 3.7, 4.0, 4.2, 4.7, 5.0, 5.3, 5.7, 6.1

Hammer 5.0 

Planchemag Magazine

Replaces last year Impact Wave and it is the hardcore manufactured wave riding sail in the brand. Its new design his more compact than the MC Wave. The construction is 100% re-enforced monofilm with Kevlar on the leech. Note, if you put the Hammer on top of the MC Wave the Hammer has less sail surface.

Sailing
When rigged, the Hammer gives more lower leech twist and has a flatter profile than the MC Wave. More rigid than its sister the MC Wave and other sails in that category, the Hammer is the kind of sail you ride with more finesse. Really reactive and more dynamic, the sail offers a very precise ride where you can get or release power from the backhand when needed. The sail does not pull and therefore you can express yourself in moves. The sail is not the lightest in the market wave segment but is one of the most robust constructions you can find. You can go for big wave riding with feeling of total confidence. It is in serious down the line conditions where you will find it at its best; dynamic and well balance. Its profile is neutral and powerful when required. This is the sort of sail you can regulate its power to gain finesse when riding in surf or jumps.

Verdict
Finesse and reactivity characterize the Hammer, which is a fast and well balance sail for hardcore wave riding. The ratio of finesse and reactivity is interesting for light sailors or other who likes fast riding. A sail we can trust with an amazing quality price.

Other Sizes: 3.3, 3.7, 4.0, 4.2, 4.5, 4.7, 5.0, 5.3

Target 5.7 

Planchemag Magazine

The novelty of 2004 to replace the Groove that used the same freemove design, light build construction on the top part and a re-enforce lower part of the sail, which is a 50% monofilm and 50% X-ply monofilm construction. The sail has the same concave leech design on mid section and larger head top part as the Hammer and the MC Wave. Overall the sail has a slightly longer luff shape than the MC Wave. We have to point out that you could rig a 4.30 m or 4.60 m mast for that stronger sailor.

Sailing
Lighter than other sails in the same range, the Target is quite a powerful sail with a longer boom length for a steady ride. This is between a wave and freeride shape where the sail seems well made, loose and also very effective. The ratio of power and finesse is very interesting, easy to sail and well balance. Tested on a 4.30 m mast length the sail felt supple and forgiving in gusts and keen in moves. The Target can be use by free stylers or wave riders and deliver an overall good performance. Another good point is, by playing on the clew tension you could get a powerful sail in light wind conditions or a forgiving one in strong winds.

Overall
A sail which has a lot of charms and the best 2004 Gun all rounder. Well built, with finesse, suppleness, lightness and dynamism, which gives a nice ride and allow you to exploit most of the sailing conditions.  A very good Free Wave.

Other Sizes: 4.2, 4.7, 5.0, 5.3, 5.7, 6.0, 6.3, 6.8

The Jam 6.2

SURF Magazine 12/03

Italian designer Renato Morlotti apparently spends nights on end in his loft, accompanied by cigarettes and coffee, working out new sail designs. His lungs and liver must have suffered during the creation of the new 'Jam', as this sail has turned out very well overall: The deep profile gets planing early, it subsequently pulls on the harness lines powerfully and steadily. Small fluctuations of the wind strength are pleasantly dampened by the relatively soft surface. The Italian has also incorporated the "power-off" function which is demanded by freestyle sailors: during manoeuvres the sail is sufficiently flat and neutral making it very forgiving and allowing it to be thrown about with little effort. Windsurfers, who like to fly over the water at the top end of the wind range with a 'smoking gun', can 'reload' by adding more outhaul, which results in more speed. Slight control difficulties which occur can also be improved dramatically with a more taught trim. Overall this medium weight rig offers a broad application range between freestyle and freemove.

TEST Report
Wind Magazine 04/2003

Judgement:
„A very well processed boom, sold directly via mail order and shops. (you don't need to have a diploma in engineering to make use of the two enclosed hexagonal-keys and to stick the spars (reduced diameters) into the front end.
In other words, the boom can be dis-and reassembled, quite comfortable for frequent travellers ! Additionally the spars come with a scale for your harness line set and are coated with soft grip material for tight and comfortable grip.

Adjustment:
Properly processed length adjustment every 25 mm.

Result:
Excellent stiffness for such a lightweight aluminium model at a "lightweight" price – Very sympathetic / likeable !!
