Mast performance

  1. Is the new 60% carbon mast interchangeable with the Hookipa 91% mast?

  2. Does the new 60% mast work well in ALL Ezzy Sails, past and present?

  3. Is the bend curve and stiffness of the 60% mast the same as the 91% mast.

  4. Is the new 60% mast softer than the 91% mast?
    No, same as the 91%.

  5. Is the new 60% mast as strong as the 91% mast?

  6. What kind of feeling does the 60% have compared with to the 91%?
    The 60% feels pretty good. I only notice the difference when I go back on the 91%, which still feels better to me because it is lighter.

  7. Will you stop producing the 91% masts in the future?
    No. We will continue with both the 60% and the 91% masts.

NOTE ON EZZY MASTS: Ezzy Mast Bend Curves
Ezzy mast bend curves are constant curve with these values:

- ¼ point: 62%
- ¾ point: 77%

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

Ezzy Masts Fit Most Sails
Ezzy masts work in all sails that require a constant curve bend.

For Sails That Require a Hard Top Bend Mast
Customers using sail brands that require a hard top bend have found success combining our top with a bottom that is two sizes smaller. For example combining a 460 top and a 400 bottom produces a 430 cm hard top mast.

There are lots of bridges, and the best sailing is often on the other side. The mast raising system can be used to handle this problem. Just lower the mast and duck under. For trailering and for going under bridges, you disconnect only the forward mast support wire. The other rigging always remains in place.

Ours is specifically designed for trailering. We use stay adjusters, rather than turnbuckles, for the wires that support the mast. With masts that are raised and lowered, turnbuckle bending and failure is very common. Stay adjusters are stronger and far more reliable. Also, we bolt the support wires to the mast, rather than using removable "T" fittings that can fall off and allow the wires to tangle up in the trailer wheels when on the road.

We use double nicopress fittings on the mast support wires because of their reliability. Swaged fittings have a tendency to crack, and it is impossible to determine their true condition without X-ray. The nicopress fittings, in contrast, are easy to inspect. We have had remarkable success with these fittings over a long period of years. On hang gliders and ultra light aircraft, you will always see nicropress and not swaged fittings. These guys really have their life on the line when choosing hardware.

At one time we used full battened mainsails. We have switched to soft sails for the following reasons: Full battened sails have to be rolled up in a long, bulky tube and take up a lot of room in the boat when stored. The battens press hard against the mast and make the mainsail more difficult to raise and lower. The long battens are subject to breakage when they press hard and chafe against the mast support wires when running downwind. They are heavier, and weight aloft is critical. They make tacking more difficult, and, for a given sail size, they are not as fast as a conventional sail.
