Petticrows Evolution Mast (eMast)The result of several years of development, the Evolution Mast exceeded our expectations in terms of quality and performance.
It was identified that a front weld taper at the tip of the mast would be ideal to ensure a smooth bend throughout its length.
This process is technically quite difficult as the aluminium selected needs heat treating (tempered) after the tapering/machining process is completed.
Two stiffnesses are available: Standard (eMast) and Stiff (eMast+).
Both sections have the same external dimensions, but the eMast+ has a slightly thicker wall section, making it overall stiffer.
The mast has been modernized with a new range of light and low drag fittings designed for easy servicing.
Choice of the traditional non-rotating boom to mast connection OR rotating boom to mast connection. The rotating style decreases the forces on the mast. These are used in conjunction with a hydraulic boom lift or the fixed style boom lift.
Sailors began using the Evolution section mast in 2018 with Jurgen Schoenherr winning Helsinki Gold Cup overall and Provezza Team winning three consecutive races – both teams were using the standard eMast.
In the 2019 Worlds Fremantle Provezza Team also overall using an eMast+ section, Klaus Diederichs 3rd using a standard eMast and Peter Gilmour 4th using an eMast+.
e or e+ sections are now standard on all new boats.
