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.


DEFINITIONS
Cam:
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).

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. Refer to your Ezzy Sails "2007 Infinity Rigging" guide. 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.
