Petticrows Evolution Mast
The result of several years of development, the Evolution Mast exceeded our expectations in terms of quality and performance. A front weld taper at the tip gives a smooth bend along the whole length of the mast. eMast or eMast+ sections are now standard on all new boats.
Why a front weld taper
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. Older mMast and iMast sections use a side weld taper.
The process is technically challenging because the selected aluminium needs to be heat-treated (tempered) after the tapering and machining is complete.
Two stiffnesses are available: the standard eMast and the stiffer eMast+. Both have the same outside dimensions, but the eMast+ has a slightly thicker wall. Both use the same rig tension settings, shown in the eMast row of Setting up your Dragon.
The mast has also been modernised with a new range of light, low-drag fittings designed for easy servicing.
Gooseneck, boom lifter and kicker options
Every Evolution mast comes with the basic gooseneck and mast ram/kicker fittings. On top of these, choose how the boom connects to the mast, then the boom lifter and kicker system that goes with it.
The traditional connection. Works with any of the three boom lifter and kicker options below.

Which mast do I have?
There are three styles of Petticrows mast. Answer one or two questions, standing at your mast, to find out which one you have.
Does the outer surface of the mast have ridges running along its length?
At the top of the mast, is the taper weld on the front or on the side?
mMast
Most older Petticrows Dragons- Smooth outer finish
- Side weld taper at top of mast
- Shrouds terminate on a bar through the mast
- Fixed or adjustable jumpers (levers usually, but not always, on the mast)
- Originally a cast mast foot; may have been upgraded to the modern aluminium style
iMast
Some boats from around 2008- Longitudinal ridges on the outer surface
- Side weld taper at top of mast
- Shrouds terminate on a bar through the mast
- Fixed or adjustable jumpers (levers usually, but not always, on the mast)
- Originally a cast mast foot; may have been upgraded to the modern aluminium style
eMast
Most boats from 2017- Smooth outer finish
- Front weld taper at top of mast
- Shrouds attach to the mast by T terminal
- Standard (eMast) or stiff (eMast+)
- Modernised range of fittings
Petticrows still stocks spare parts for the iMast and mMast sections. Rope rigging was introduced in 2010, and since 2016 mast movement at deck level has been limited by an IDA rule change.
Masts on v6 and v6.1 boats
- Longer shrouds, because the attachment point is lower in the boat
- A different, more rounded mast collar
- Aluminium mast foot
- Shorter mast ram bottle screw
- Adjustable diamond levers fitted in the boat under the floorboards, not on the mast
- Modernised gooseneck fittings, fixed or rotating
