MauiSails sail rigging tips
By Artur Szpunar
Downhaul (DH) measurement
Downhaul (DH) specification measured from bottom of the mast to the bottom of tack pulley.
This photo shows DH=5cm for a Mutant 4.6. Base extension must be set at next higher setting above the DH specification. For example of DH=5cm, base extension would be set at 6 or 7cm.
Boom specification measured from clew to front of the mast at center of cutout.
This example shows Mutant 4.6 measuring 164cm. Sail should have between 1-2cm of positive outhaul after being fully downhauled.
Visual downhaul and outhaul check
Once downhauled and outhauled to specification, the tip of the batten above the boom should sit right at the back edge of the mast.
When rigged correctly, the sleeve should be taut, midway between the top 2 battens.
The Mutant combines soft, light handling and playful maneuverability with balanced power and stability. The shaping and body tension of the sail have been conceived to match the short outline which keeps the sail composed in a huge range of conditions. The Mutant planes on a size smaller than normal, while remaining light and in control on the top end. The reduced rotational inertia of the ultra-compact outline and the ability to use a smaller size drives the insane maneuverability and facilitates looping and modern wave maneuvers. Sizes from 3.8 to 5.1 fit on a 370 mast or alternately the 3.8 and 4.2 also perform on a 340. The largest 5.6 size requires a 400.
The Mutant's layout and construction is based on using the best materials for light weight and durability. Generous use of ultra-light and strong Technora™ scrim in the upper sail body, bomber 5-mil X-Ply™ along the leech and foot, and an oversize optical X-Ply™ window in two custom thicknesses all add to the durability and value. The name and graphics of the Mutant are inspired by the idea the sail should feel so light and natural it is like an evolved wing that is actually part of you.
