View Full Version : Masts

Hi Roger,

Are the Sailworks masts exactly the same masts as the Powerex masts (made by the same manufacturer but with different names put on the masts), or are they different masts?

If they differ from each other, how do they differ?

Hi Filip,
According to Bruce Peterson (who I consulted on this subject):
Lipstick = Z-Wave
Joystick = Z-Free
Speedstick = Z-Speed

However, the Sailworks Backbone RDM has a stiffer top than the Powerex RDM.
With the following exceptions:
One exception to the "Speedstick = Z-Speed" is the 520 model; the Z-Speed 520 is made on the large OD mandrel like the 550, whereas the Speedstick 520 is made on the the smaller OD mandrel like the 490.

Also in 2006, when the Powerex production moved to China, all the 430, 460 & 490 mast changed to slightly larger top sections, but this was the same for the all the comparable Powerex and Sailworks models.
So, there you have it!
Essentially they are the same, made in the same manufacturing plant, using the same processes.
The Sailworks Backbone RDM is made to a different specification than the Powerex RDMs.
This can be used to open the top up slightly more on sails such as the Hucker.
I take a look at the windspeed, and if I'm thinking I'll be a little overpowered on the Hucker with a Joystick SDM or the Backbone RDM I'll rig the sail on a Powerex 90% carbon Powerex RDM Prepreg Wave
mast, to take a little power out of the top of the sail.
Hope this helps,
