great work fella! very handy this. Those germans are awesome, but dont mention the war.....a mate couldnt get severne sails to work on his ezzy masts, ended up changing to severne masts as well. another guy I know tried simmer on his NP masts, and it looked crap, floppy low down but head tight. table looks like it works.

Hmm I use powerex in my Severne Blades which is pretty close to Ezzy masts(not recommended above) and my blades are frickin awesome.

Yep that table is up the ****. I run Ezzy's in my S1 and SWATs and have rigged an S1 and a SWAT back to back with an Ezzy mast and an Enigma, the difference is not huge. As Rider5 says the Powerex are for all intensive purposes identical to an Ezzy. From my experimentation Severne's are designed around a slightly stiffer tip mast rather than 'constant curve' which both the Powerex and Ezzy are, but they still work really well on both the Powerex and Ezzy imo... not rigged to the exact settings as per a Severne mast obviously.

I should also clarify this by saying that most people have no idea how to rig their sails, nor experiment outside of the 'recommended settings' in order to find the sweet spot for their particular setup. This might sound harsh but it's an observation I've made over the years.

could some one explain to me why some cant match

i thought if the mast was "ya" big , it can fit the same size sail ,
does it have to do with the flex ?

Yes it is to do with bend curve and flex and were it is. NP tend to be flex top gassta and severne hard top Gun sails mast are in the middle constant curve.

Not sure how correct that is for Hot Sails, in my experience they work well with tushingham (only from rigging, didnt get a chance to try it on the water, but the cams rotated and the leech acted the same as with the hot rod as downhaul was applied), tush and hot sails have quite a similar bend curve, flex top but closer to constant curve than NP. Whereas North was not as good with the hot sails, it would need spacers to work properly.

I have also used a severne blueline on my simmer SCR and it was perfect.

North mast on a Tushy X15 gave it more grunt and speed off the wind, with great rotation.

Billyboy....picture the mast either bending more at the top, or constant, or lower down with little bend at the top....this has to fit tightly in the luff tube which is not stretchy and hold the intended shape of the sail. Different manufacturers have different philosophies, for example some say that a flex top dumps power better but sometimes creates a flatter sail in my limited experience...however the Hot Sails GPS is the counter example to that.....it does get complicated

i also question the accuracy, but thought id share anyway

Then there's the consistency with which masts are manufactured. Someone posted some measurements a couple of months ago, which maybe weren't all that carefully done, but they showed a lot of variation in the "soft top/hard top index " between two measured masts from the one manufacturer.

Do they soften with use?

I don't think anybody's having a go, just that "average" isn't defined and that may mean anywhere from OK through to damn near a red box.

I think there are some that will work that supposedly don't from the table, but it is still very handy for noobs. Much easier to read than the data on the Peterman.dk link that is always posted
Of course the data will change over time

OK - picture how these exaggerated masts would rig the same sail differently because of where the flex is. What if a sail was designed for the mast one the left and then rigged on the mast on the right? Just don't ask why manufacturers do this or you'll be cursed with mast breakage.

Geez Pat, and I thought I had a stiff top.

Appears not......

thank - found that very usefull ,

is there a rule of thumb ,
is one faster then the other , or better in different case ,
eg why would you use a flex top and not hard top

It worth remembering that for all the different bend curves, ie. hard top, constant curve, and soft top, the top of the mast is softer (bends more) than the bottom, its just how much more.

Such that a very hardtop mast, actualy looks closer to a constant radius curve. i.e. the top is nearly as stiff as the bottom.

No windsurf mast would ever look like the example on the right, the most 'hard top' mast might look the example in the middle.
