Ezzy Cheetah

Our go-to flat water sail, the Cheetah has a soft, locked-in race feel. Camless and easy to rig, the Cheetah’s deep foil provides power and speed. When we freeride, we want to go fast, nail 100% of our jibes, and rocket into the air if a ramp appears. This is the easy freedom that inspired the Cheetah, and what the Cheetah delivers. The Cheetah is pure freeride but can hold its own against any race sail. The forgiving, soft feel makes the Cheetah a dream to gybe. The Cheetah rigs on all RDM and SDM masts. And, like all Ezzy Sails, the Cheetah is built to last.

  • New Material = Lighter, Softer, More Maneuverable A lighter scrim not only reduces the Cheetah's weight but also makes the sail softer, so it glides through lulls and maneuvers effortlessly. Also for 2016, the 6.0, 6.5, and 7.0 have 6 battens instead of 7, making the smaller sails feel lighter and softer.
  • Flatter Shape Above the Boom = More Control The profile above the boom is flatter to give the Cheetah more control when the wind picks up.
  • Smoother Twist = Faster The batten spacing is more progressive, which means that the battens are closer to each other nearer to the head of the sail. This creates a smoother twist in the sail's profile, which translates to more constant power, more control, and a higher top speed.

A portion of every sail we sell goes to help schools in Sri Lanka.

The Ezzy Hookipa Mast

Ezzy Sails work great with the Ezzy Mast system, but also work with a variety of other brand masts (RDM and regular diameter). You could contact your mast maker and see if the bend of your non-Ezzy mast is compliant.

Ezzy mast bend curves are tip: 75% to 79% and base: 62% to 65%

Note: this is not carbon content. This is percentage bend relative to the midpoint bend.

For further info on Ezzy Mast sizing, please refer to our Mast Configurator Tool

Our removable, 316 stainless steel tack pulley can be replaced with our 316 stainless D-ring for those who prefer a grommet with a pulley hook.

  • Andrew

    Hi there – I’m currently rigging my 2015 Cheetah 7.5m on a Ezzy 490 Top/430 Base mast. I have been rigging it according to the factory setting of the down-haul indicator, however I would like to confirm if this is the right approach or whether I should set the downhaul according to the looseness of the head first, and then reposition the down-haul indicator accordingly. Please let me know what you recommend. Many thanks, Andrew

    • ezzysails

      It is a good idea to assume your combo mast might not be exactly the right length. I’d suggest you assume you should re-calibrate your rig.

      I grabbed this section from our rigging guide. Hopefully this answers your question:

      a) First, make sure you have NO outhaul.
      b) Then, downhaul until the looseness on
      the leech extends to the four dots printed
      between battens #2 and #3 (figure 2).
      Note: to see the looseness, the leech at
      the dots must be touching the ground.
      c) This is the medium wind setting.
      d) Next, move the downhaul gauge at the
      bottom of the sail so that the medium
      mark of the gauge lines line up with the
      bottom of your mast (figure 3).
      e) The downhaul gauge is now positioned
      correctly. From now on, to set your downhaul,
      just downhaul until the the gauge
      lines up with the bottom of your mast.
      Note: When observing the looseness at
      the dots for this exercise, the sail must
      have no outhaul. When you apply outhaul
      the leech tightens.
      Additional Information:
      – Do not over-downhaul. Too much downhaul
      will make the sail unstable.
      -If you feel back-hand pressure, apply
      more outhaul.
      – If you change to a different mast, you
      will need to repeat steps a) through e).

  • Erwan Couëdelo

    Hi there,
    I have to find a (second-hand) mast for my Cheetah 7.5. (I would also use it for my wave SE 6.3). My surf spot (Poetto Beach – Sardinia – Italy) is usually flat with sometimes a bit of swell. I know that a constant curve is required, but it terms of diameter; what’s best: RDM or SDM? Plus, what is the lowest percentage of carbon to make the sail works well? Thanx for your advice, Erwan.

    • ezzysails

      thank you for the message Erwan. RDM masts are very nice because they are very strong and they are very easy to thread and unthread from the sail. SDM masts can be made very light when they are 460 and 490cm length. You can’t go wrong with either kind of mast as long as you get a mast with the right bend characteristics. Have you checked out our “Legacy” 60% RDM masts? That might be a nice way to go. Buying used masts can be a little risky…

  • Philip Evans

    Hi ,does it take one sail for the cheetah to stretch ,as I rigged as soon as I brought it ,it seemed stiff and didn’t set right ,the second time it looked amazing .Im loving this new 6 batten cheetah ,it seems so soft .And still great bottom end .I brought the green and red ..wow you can see it for miles . This is my first cheetah .

  • Artem Lavrynenko

    Hello, I have an issue with selecting my sail. I’m heavy guy and when it’s not too windy I need a large sail to plane but I have problem to water start with big sail. Any suggestion which sail to buy.

    • ezzysails

      thank you for the message Artem. A part of me would like to suggest the twin cam sail called the Lion. I like the way cambers make the sail feel more powerful and easier to sail upwind. Some sailors find cambered sails more difficult to waterstart…but I find the exact opposite . If you take the time to set the rig up and clear it from the water, I think the Lion is easier and quicker to pull you up and out. This is really my personal experience, and you may find different. I would suggest you speak with sailors and windsurf shops in your local area…they may have some great feedback regarding the best gear for your local conditions. Hope this is helpful!

      • Artem Lavrynenko

        Than you it helps. Would cambered sail pulls you upwind more even you don’t want to, during the gust?

        • ezzysails

          not necessarily. Getting pulled upwind like that is usually a sign that you are over powered. You can really temper things if you flatten your rig (more downhaul and outhaul) and also consider using a smaller fin. This will mellow things out.

          • Artem Lavrynenko

            Thank you very much. Here is dilemma I have. I’m looking for light winds short board sail as well as strong wind 25+ long board race sail. I cannot afford to buy two so what would be my option.

          • ezzysails

            I’m afraid you are looking for two very different sails. You should look for used sails, or perhaps consider the Legacy model (much cheaper).
            You will have better sailing experiences and enjoy windsurfing much more if you don’t box yourself in with too many financial limitations!

          • Artem Lavrynenko

            Sorry, I did reply but I’m not sure where it went, so I repeat myself. The main feature of the longboard race sail is ability to go upwind. But this only matters in a wind range 0-25knt. When it gets windier 25+ then I’m not worry about upwind anymore but speed. So basically any good slalom sail will do the job. I’m debating between Cheetah 8.0 and Lion 7.5 as you don’t have Lion 8.0 and 8.5 a bit too much for 25+ condition. Taking all this into consideration what would you suggest. Thank you.

          • ezzysails

            we sent you a direct email to your gmail address.

  • ezzysails

    I’d suggest the 6.0 Cheetah. The scaling from a 6.0 to 6.8 seems more natural and comfortable to me than a jump from 6.8 to 5.5…particularly for the Great Lakes!

  • ezzysails

    Ezzy mast bend curves are tip: 75% to 79% and base: 62% to 65%. I believe Unifiber masts are a bit softer in the tip. I think they are okay in our sails.

  • jb

    When I de-rig my Cheetah sails I follow your video advice of spinning the mast, presumably to help the mast ease out of the mastcap and to release any suction between the leech sleeve and mast. However, when I spin the mast, the sail pulls together at the boom opening and crinkles the fabric. I just can’t seem to remove the mast as beautifully as Dave does in his video. Do you have any other tips? Thanks!

    • ezzysails

      thanks for reaching out. When the sail is wet, things are going to work slower than on the video. I’d suggest a bit of patience and spin the mast slow. You might send an email directly to David at [email protected] too.

  • Stephen McFarlane

    I’m looking at purchasing a cheetah 6.5 and a lion 7.5. I have a goya 430 90% rdm and am looking at buying a 460 ezy rdm for the lion. Will the goya mast be ok ( rider weight 100kg) or should i look at getting a 430 half ( base or top)
    Cheers Steve

    • ezzysails

      thank you for the message Stephen. I believe Goya masts are the same bends as ours…though I would recommend you confirm with them if possible. Our masts are all based upon 75% to 79% and base: 62% to 65% percent bend curves relative to the midpoint.

  • marc

    hi Ezzy
    I’m using a RRD fsw 96 l in lakes only;my biggest sail is 6.5 and I like overall enter gybes at full speed:so I should go for cheetah or lion to fit with north mast 100% sdm?
    thank you for the answer.

    • ezzysails

      great question Marc! I’d point you towards the Cheetah. The Cheetah has a fuller foot profile, and pulls more than our Tiger/Zeta/Elite models would. You will find your ability to get cranking speeds yet enjoy the nimbleness of the “freeride” cut will work well on those FSW boards. By the way, I think they are some of the finest boards out there!
      I think the Cheetah would deliver the power and easy rotation, making it a good partner to the FSW design. The Lion wouldn’t be my first pick.

  • Emm Ech


    I have a Chinook 150-200cm boom. The inside width is 35.6cm. Will the 2016 Cheetah 6.5 work with this boom? My concern is whether the narrow width of the boom is enough for the draft of the sail.


    • ezzysails

      thanks for the inquiry! The 6.5 Cheetah will work great on your boom. The max outhaul for the 6.5 is 196…and that setting is for full flattness.

      Believe it or not, David is 100% okay with the fact that a sail come into contact with the boom on the leeward side of the rig. Even though you might think it would interrupt the foil, it is totally okay in the scheme of things. Feel free to call David to verify at 808 575 2566

  • Denis

    I’ve just bought a Cheetah 6.5m and intend to use it with a 4.3m mast base and 4.6m mast top. I’ve noticed this isn’t a combination listed in your mix and match table. Will this mast combination still be OK. I was planning on using a 10cm mast extension.

    • ezzysails

      great to hear from you Denis. Your best bet for the 6.5 is to rig it on a straight 430. The 460 tip/430 bottom is an option that will work, but the sail will feel a bit nicer on just a 430 tip/430 bottom if possible!

  • Thomas Sherriff

    Will a Powerex mast (Windpreg 460 SDM) work well with the Ezzy Cheetah 7.5m? I know they say “constant curve” on their website, but since they became a Chinese based company, there’s been a greater discrepancy with their curve when compared to when they were a US based company.

    • ezzysails

      great question Thomas. I wish I could say definitively that the Powerex bend (China) is right, but I am aware they made changes to the bend percent curve while they were in production. It is difficult for me to give you a clear answer.

  • Johnny

    Could you please suggest the size of the cheetah? I am 86kg and I plan to use the sail on lakes with light to medium wind 13 to 18knots. I am undecided between the 7.0 and 7.5 size. I am an intermediate windsurfer with a large board a 130lts. Thanks

    • ezzysails

      I would suggest the 7.5 Cheetah. The sail will rig on a 460, which is very nice. The 7.5 sails overpowered quite well, so you could use it in higher wind until you need a 6.0 or close.

      • Johnny

        Thank you.

      • Johnny

        Thank you. I did decide to buy the 7.5 Cheetah. I want to upgrade the boom, I have an old alloy boom. What would be a carbon boom that goes well with the board.? Thanks

        • ezzysails

          I’m a big fan of Chinook booms. Their carbon booms are amazing, but even their pro alloy boom is quite nice and stiff.

      • Johnny

        I ended up buying the 7.5 Cheetah. I love it. I have a north sails mast gold 460. It seems it is working. What is your opinion on how this mast fits the cheetah? Thanks

        • ezzysails

          the North masts work great in our sails! you should be very happy!

  • llstevek

    Is the spread from an 8.0 Cheetah down to a 6.8 Elite reasonable? Thanks…Steve

    • ezzysails

      The 6.8 to an 8.0 is an excellent way to scale your quiver! Yes yes!
