Quick to rig, the Lion3 is one of our favorite sails because it makes going fast no-hassle. After much testing, David made the Lion3:

  • Lighter The Lion3 weighs less than the Lion2 because of a new, lightweight scrim, making the sail easier to handle.
  • Faster Progressive batten spacing (closer towards the top of the sail) produces a smoother twist.
  • More controllable in strong winds The profile above the boom is flatter to give the Lion3 more control when the wind picks up.
The Lion3 is a race sail stripped of everything that makes race sails difficult. The luff sleeve is narrow and easier to waterstart or uphaul than a wide sleeve that fills up with water. Like the Lion2, the new Lion3 rigs on all RDM and SDM masts. And, like all Ezzy Sails, the Lion3 is built to last.

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

Instructions For Custom Fitting Ezzy Cams To Your Mast

The Ezzy Cam System will fit any mast. Before rigging for the first time, follow steps 1 through 6 to learn how to find the correct cam and cam pocket for your mast.

**Note to Ezzy Skinny Mast owners: You do not need to measure your mast diameter. We have listed the correct Cam and Cam Pocket combinations in the chart at the bottom of this page.


Red plastic camber inducers, which sit inside the luff sleeve, behind your mast. The cams come in three sizes which are marked: "Standard", "Medium" and "Skinny".

Cam Pocket:

A spacer made of sailcloth. The arms of the cam fit into the cam pocket. There are 9 different sizes of cam pockets, marked "A" to "I". Having the correct length cam pocket allows you to set the right amount of sleeve tension for the sail at the cam. If the mast sleeve at the cam is too loose you would change to a shorter cam pocket. If the mast sleeve is too tight you use a longer cam pocket (see the bottom two diagrams on the back page).

(click to enlarge image)

Note: In addition to the cams and cam pockets that are in your sail, you will find an assortment of cams, cam pockets and a measuring ruler in the velcro pouch of your sail bag.

Step 1.

Lay your sail on the ground and open the velcro slots that are located in the sleeve at each cam. Notice how the arms of the cam and the cam pocket go on either side of the batten stopper (this will be important to know when it comes time to reinsert the cams back into the sail).

Remove BOTH cams AND cam pockets from the sail.

Step 2.

To find where your cams will sit on your mast: check the luff length that is printed on the foot of your sail.

Adjust your base extension to this amount.

Then, line up your mast beside the luff sleeve.

With your extension inserted into the mast, make sure the cleat is even with the bottom of the sail.

Step 3.

Use the included ruler to measure your mast's circumference at both cam locations.

Step 4.

Refer to the charts below and locate your circumference measurement. Read the letter below the number. This letter is the cam pocket you require. The correct cam is listed on the right-hand column on the same row as the cam pocket letter. Example: If the mast circumference at your upper cam position is 14.0, you would look at the chart labeled "UPPER CAM" and find "14" along the top of the chart, then under the 14, the chart indicates you would use pocket "F" and looking all the way to the right we see the cam marked "MEDIUM". If the circumference at the lower cam measures 16.5, you would refer to the chart labeled "LOWER CAM" use pocket "D" and the cam marked "STANDARD".

Step 5.

Once the correct cam pocket is found, insert the cam arms into each side of the cam pocket.

Step 6.

Insert the cam and cam pocket into the sail by holding the guide flaps and sliding the cam arm into the openings on either side of the batten stopper.

Push the cam all the way until it is fully seated in the sail.
Your cams are now set and you are ready to rig your sail. Note: If you ever get a new mast with a different diameter, you will need to follow the above instructions again in order to fit the cams properly.

Note on Ezzy Masts

How To Choose The Perfect Mast Combination For Your Quiver:

  1. Pick the top and bottom that fits the sail you use the most.
  2. Use a longer top for your bigger sail.
  3. Use a shorter bottom for your smaller sail.
= Best Combination
= Good Combination

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.

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.

    I read somewhere that the lion can be rigged without the cams. In that case, will the lion perform very similar to the Cheetah?


    • ezzysails

      thanks for asking. Truly, it is best to rig the Lion with the cambers. It was designed to be a cambered sail. Years ago, with the Infinity, we encouraged people to sail it with the top camber out if they wanted to experiment. The Lion is not really built to be a convertible sail.

  • ezzysails

    hi JL,
    Its been a long time since I’ve sailed a 4 cam sail. Lots of multiple cam sails like that were built for racing…particularly for course racing that emphasizes sailing straight up or down wind. The Lion has great low end power, stability, and can sail all points of sail. It ISNT a race sail, so it isn’t designed to sail two meters overpowered necessarily. Lots of racers liked to take a big sail (like a 7.5) out when others are sailing on 5.0’s. The Lion is a tested and loved all purpose light air sail

    • Jean-Lin Spriet

      So it is not meant to be sailed overpowered, is it ?

      • ezzysails

        the Lion sails overpowered great, but it doesn’t have the same speed pointing directly up wind or down wind as a traditional 4 cambered race sail.
        If you are course racing, the Lion will be nice….but not as fast.

        If you are just looking to enjoy a high performance sail for all purpose windsurfing, then the Lion will be great.

  • Jamie N Penny McCourt

    Hi guys how would I go using a hot sails Maui 430 98% hotrod rdm for a lion 6.5. How would the downhaul calibration marker be close enough.

    • ezzysails

      hi Jamie,
      Thanks for the inquiry. The specs I found show the Hot masts aren’t a great fit in our sails. The MCS/IMCS measurements are quite a bit different than our recommended coordinates. The length would be fine, but the overall set-up of the sail wouldn’t be optimum.

  • Takao Sakamoto

    Can I use the 460 mast for 8.4 lion3?
    I have a long extension set to 43cm.
    And let me know the hight of the middle of boom opening from the bottom of the extension.

    • ezzysails

      thank you for the inquiry. The 460cm mast on the 8.5 Lion is a little too soft for optimum performance. We recommend the 490.

  • ezzysails

    thank you for the kind message Mr Foe. I am not familiar with switching the battens out in the Lion. I believe David wouldn’t advise it, but you might contact him directly to get the specifics. His email is [email protected].

    Hi! I have a 8.5 Lion3 from last year and I love it. Amazing range. I also have a Cheetah 6.5 and 7.5. Great sails but the 7.5 Cheetah is overlapping the range of the 8.5 Lion a bit too much. And I do like the Lion better than the Cheetah on a 120-130L freeride or freerace board. So I would find very useful to produce a few sizes “in-between”: how about adding a 7.0 and 8.0 Lion3 for 2018?
    Ideal quiver: 8.5, 7.0, 6.0 or 9.5, 8.0, 7.0. The Lion3 has so much range that jumping 1.5m2 in the big sizes would just be fine.
    Otherwise, I would revisit all sizes that way and get ride of one of the sizes: 9.5, 8.2, 7.0, 6.0.
    But what do I know? Love the sail anyway in any sizes!

    • ezzysails

      thanks for the feedback! We are actually bringing back the 7.0 Lion for 2018. The 8.0 isn’t going to be a size for 2018, but we will keep it in mind moving forward.

      • gdeswarte

        Very good news. 🙂

  • FP

    I’m thinking of getting Lion for WindFoil sail. I tried Lion3 6.5 on Hookipa 430 mast and I realy liked the stabillity and range, but since I would use WindFoil just in winds bellow 15 knots, I’m leanning towards 7.5 size. Can I use Neil Pryde SDM 460 X100 mast in Lion3 or 2018 7.5?

    • ezzysails

      great to hear from you. it is so fun hearing about all of the experimenting going on with foiling!
      Yes, they Pryde 460 is a good mast for our 7.5 Lion. Hopefully you can put the 7.5 Lion to the test!

  • Ιωάννης Γκόκας

    I am about to receive a new Lion 3 6.5 m which I wish to rig it on a rrd vogue 430 100%c rdm mast.Will it match?

    • ezzysails

      great question. Our sails work best on a mast with – ¼ point: 62%
      – ¾ point: 77% . The RRD mats are – ¼ point: 61.5 to 62%
      – ¾ point: 77 to 78% .

      This means they are close to the same bend. I would expect the performance to be good, but not exactly what we like.

  • Ιωάννης Γκόκας

    Hi again!
    First day on my lion 3 6.5m and I was happy to see it’s early planning(average wind about 12 Knots).I tried to follow all rigging instructions but many wrinkles insist to spoil the beautifull profile especially in the area between cams and close to mast sleeve.I noticed that velcro could not close well in the upper cam so do you think i can try with a smaller pocket (move from e down to d).I use rrd rdm vogue 430 mast.Or I must trim batten tension?
    Thanks in advance!

    • ezzysails

      wrinkles are good! Our sails are designed to have lots of wrinkles while in dynamic mode. The key question is how it feels.
      I suggest you snap a photo of the sail rigged up next time you go sailing. Take the picture as follows, and email it to David for review.
