RE: Putting an NP Excess 6.9 on a Kombat 97?

In my opinion, it makes little sense to push too much sail size for a given board. Usually one ends up loosing in balance what he achieved in power, and no earlier plaining is attained.
That said, IMvvvHO this issue is somewhat related to boom length. I remember a slalom board of mine that was simply perfect with a 6.0 and did not want to behave with a 6.5. When I changed sails, and got a 6.5 with a boom length similar to that of the older 6.0, then the board was really OK with that new sail. I guess boom length (not considering clew indented sails here) can be considered as a rough guide of how far back the center of pressure is related to mast foot position. If you second this, you will prefer the Excess over the Expression due to its shorter boom; X-Ply construction will be a nice plus.

RE: Putting an NP Excess 6.9 on a Kombat 97?

Of course I would like to do everything... but during 6.7 days I think that blasting and B&J is what is most appreciated. Still not neither wave- nor freestyle guru, but the goal is to get the basics of both disciplines going. My gutfeeling says that Expression might be too freestyle-oriented(?)... and the available size (6.7 vs 6.9) gives the Saber a pro over the Excess, regarding recommended sail sizes... still the X-ply solution is interesting, if it gives better duarbility (also over the years...)

Guest(s),

Sorry, don't have tried a Saber on my K86 yet, so can't comment. However, my slalom RS-1 6.6 is absolutely fine for blasting and B&J, no mismatch at all, so I guess a Saber should be fine too for what you want to do as described above.

The Saber, Excess and Expression are all crossover sails according to NP classification, but each with a distinct flavor/focus/subspeciality as follows :

- Saber : sail mainly designed for supercross : fast, locked-in feel, very powerful but manoeuvrable enough for doing the supecross figures.
- Expression : sail mainly designed for freestyle : soft feel, very flat and light in the hand for maximum handling during figures.
- Excess sail falls in between and is in my taste a perfect crossover sail with the Kombat, i.e., a good match for freeride, freewave and freestyle do-it-all sail.

So, I would say it depends on what freestyle figures do you want to attempts or have in mind in your final choice ? Tell us more about that...

Cheers !

Hey guys,

anyone know how the Saber 6.7 works with the Kombat 97?

Saber classified as crossover sail, Kombat is a crossover board... Am I missing something???

Hmmm, ok thanks for your info bros...

6.7-days is mostly happy freeriding in winds 12-20kts, with blasting and chop-jumping, and maybe some minor frestyle attempts. From what Ola says, is the Saber not the optimal model? What other sails could you recommend for this type of sailing?

(sorry, the edit function doesn't work anymore to add further comments)

As for potential imbalance problems with the Kombat 86, I didn't experience any so far, providing the boom lenght is not greater than 204 cm (Jet 6.9) or 202 cm (RS1 6.6) with the freeride setup (mast-track 40-50%; all 4 straps back and outboard, stock 30 cm freeride fin set in the middle of its finbox as recommended). However, with the wave setup (mast-track 30-50%, all 3 straps front and inboard, wave onshore 23/24 cm fin set forward as recommended), I must acknowledge that pointing upwind with the Jet 6.9 sail is a bit less efficient than say with a smaller sail such as a NR 6.2. The Carve 111 still is far superior with the Jet 6.9 sail and a wave setup, even with a stock 2001 25 cm freestyle fin.

Cheers !

RE: Putting an NP Excess 6.9 on a Kombat 97?

Agree with Ola. A Saber will be more powerfull than an Excess than an Expression :

http://www.neilpryde.com/sails/sail-technology/foot-curve-2.html

The Saber is more deeply drafted and has more foot area than either the Excess or Expression. Therefore, a Saber 6.7 might be as powerfull as a 6.9 Excess or a 6.9 Expression.

It also depends a lot on what program do you want to focus on (speed versus manoeuvrability) :

RE: Putting an NP Excess 6.9 on a Kombat 97?

I agree with JM, but its worth adding that how big sail you can put on a baord is not only a matter of "performance" but also depends on how much "imbalance" when just planing you're willing to live with and that your technique can compensate for.

In any case, on a given board, in the end you come to a point where more sail area will simply not let you plane any earlier. My GUESS is that a 6.7 will be at least as effective as a 6.9 on a Kombat 97 for most people. Sails charactersistics wil matter to btw. Lighter, flatter and "springier" will let you go further than loose leach, deep profile sails because you can be more effective with pumping in the crucial stage when just getting onto a plane.

I have a Kombat 97 inbound... but I was thinking if I could push it even more, by getting a NP Excess 6.9...
Having been accustomed with a 2001 Carve 111, stock freeride 32 cm fin or freestyle 25 cm fin with a 6.9 sail combo, I've tested a 2005 Kombat 95 with a NP Jet 6.9 (ancestor of current Excess 6.9) sail and either a freeride 31 cm fin or a wave onshore 23 cm fin. I didn't experienced any problem, mainly because the OFO width is about the same at 40 cm as that of the 2001 Carve 111.

Now, I'm using since 18 months a 2006 Kombat 86 with my Jet 6.9 sail, either with the stock 30 cm freeride fin or with a wave onshore 23 or 24 cm fin, all with great success and fun. For my 65 kg, the Kombat 86 felt much nicer and more lively under foot than the Kombat 95, surprisingly even with the 30 cm fin and 6.9 sail combo.

So with your 75 kg and Kombat 97, I can't see any reasons why it shouldn't be as nice and fun as it is for me with the Kombat 86...Go for it !

Cheers !
