It is the modern wave-sails that calls for longer lines. The modern sails are used more upright, compared in the old days. It is also much more comfortable with longer lines in float and ride conditions.

I'm 175cm and I'm using 34" lines in waves, and adjustable ones at around 32" for slalom and Formula.

The Gorilla, Blue, and Red SeverneRDM masts are identical, except for the 1 layer (Blue) or 2 layers (Gorilla) of glass for strength. Makes you wonder why the Red is more expensive than the Gorilla as it requires less material and labour. Guess it's a higher quality prepreg carbon.


I don't know where you are getting that from?
Carbon fibres come in a variety of qualities and price ranges. The highest quality (and most expensive) carbon fibre have a higher elastic modulus, compare to cheaper fibres. The higher modulus means that you need less of the fibre-composite for a certain bending stiffness of the mast. This means a that lower wall thickness can be used, and hence the weight is lower. Severne then use the T800 fibres from Toray in their "Red" line and not in their "Blue" line. So the blue line will need a thicker wall, compare to the red line, in order to have the same bending stiffness in the mast.

If we are talking about RDM masts, I think that the Severne Blue is good enough and very close the Red ones in terms of feeling on the water. The Gorilla (I have one of the Gorilla II) on the other hans feels a little too different, it feels "stiffer" and might have a slightly different bend curve too. So Blue is my choice for RDM masts.

Here is a picture of the PB fin:

K4 are great to deal with directly on their web-site, great service, they even reduced the cost for me in order to compensate for the import taxes.
(as UK are not in the EU anymore and I live in Sweden)

But the PB is in the "wrong place" for regular PB fins, you would have to get the special, off-set, one from MFC. On the older and smaller One-boards, they used a regular US box. This allows for more tuning, in terms of position, depending on the spot and conditions.

So what is it like on the water?
The fin tuning and choices seem a bit limited with MT for the side-fins and the odd, rewards, position of the PB centre fin...?

Yes, it is the wood layer that is cracking. It is good to seal them, while they are mostly cosmetic, in order to stop them from growing. I have used thin, slow curing, laminating epoxy to saturate the cracks and it seems to work well enough.

Let the board dry thoroughly and they let the thin epoxy wick into the crack. I have boards that are +20 years old now, the cracks that I sealed +10 years ago have not grown since then...

Yes, a larger board (thrusters are great for all-round use) and a lightweight ,smaller, rig works very well. The latest "regular" S1 sails are really lightweight too, so match that with a lightweight carbon boom and the difference to the older rigs is a great feeling. :)

That's unlucky, I wish you a speedy recovery.

As other have said, I'm also surprised that you would crack a rib without having a proper crash, even with an object in a pocket. I've only cracked a rib ones, it was in a snowboard accident when I landed very hard on my own fist. But that was a violent crash where I was happy I got away with only a cracked rib...

I'm guessing generation 12, which is what they are at currently.
Volume matters too though, as they are quite different from one size to another.

I have an 86liter, generation 1. :)

It also depends on were you live and sail.
I have plenty of sails that are 10-15years old and I have never had any problems with UV-degradation of the monofilm (I live and sail mostly in Sweden).

I have the Ion Vector too, and it works fine with a waist harness. They are a bit small in their size, so I had to go one size larger than usual in order to breath normally. It is comfortable to wear and feels like it gives some protection, but I have never hit anything hard enough to tell. It gives some extra floatation when waterstarting, which is nice in the winter when one doesn't want to put the head under water.

Both the Moto and the NCX have four rollers in the sail, and hence they need three rollers in the extension. The designated RDM extension from Severne is labeled "Triple X".

Note that there is no "pin" to remove in these sails that would make them compatible with the Cyclops extension.

Yes, nothing beats the race sails on a downwind course (I have M1 and M3 sails), just let off on the outhaul, bare off and hang on. :)

Sboardcrazy, if you haven't tried an adjustable outhaul yet, I would strongly recommend to try it. It makes a world of difference to be able to adjust the power whilst sailing.

Looks like some visual tuning to me.Still on current 2026 info.Minimum setting should have some loose material between top 2 battens..simple.


You also have exactly the same file and images for the Blade, S1, Gator, Convert and NCX sails.

Regarding the cartoon image that shows the rigging of the sail, I'm pretty sure that it hasn't been changed during the last 15-20 years, while the sails certainly have. So it doesn't mean much anymore.

I once rented a Blast at the Garda lake in Italy and I didn't like it all in the chop that they get there. I think it is more deigned for flat water blasting (kind of free-race) rather than choppy bump and jump conditions. From Fanatic the Gecko was a much better all-round board in the same conditions. Lots of fun in a more tradition free-ride shape. :)
