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 measurement

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 lower aspect ratio and slightly wider sleeve with more lightweight XPly ensures the best application of extra cam pressure to stabilize draft. The continued use of flexible materials also makes the rotation soft and easy.

The desirable handling character and fluid maneuvering is a design trait from MauiSails that is already well known. Formula Experience racers find the new slightly flatter profile aloft matches perfectly with the deeper sections around the boom for acceleration and top speed control. Refined adjustments to leech seams respond to the moderate downhaul that results in the correct setting of the twist.

The increased use of X-Ply materials, including our custom gradient 3mil, creates a color shifting palette for a most attractive appearance.  Tensioning the battens via our custom end fittings smoothes the trailing edge on both tacks evenly and the four tube/rod battens guarantee shape stability and light weight.

The sleeve design always drains water quickly. Recovery and water-starts after falls is simple because of the minimal sleeve. It is only as large as necessary to rig with cams off. The greatest effort has gone into having rotation to jibe like an RAF, so we are almost forgetting there are cams.

Sleeve and tack area are protected from damage by a lightweight covering and the deep cutout is perfect for easily attaching the boom, especially when using the MauiSails custom carbon front end design. We recommend the use of an adjustable outhaul and include an integrated lightweight loop-on clew pulley as the low friction solution for full race capability.

The 2013 Titan-GS is the ideal sail for easy Freerace sailing, with manageable power and competition speed.

The bits and pieces:

  • Generous use of highest quality U.S. made Xply material.
  • Low profile batten tension system with stainless steel adjustment screws.
  • Tube/rod battens have tapered batten pockets to keep tips straight.
  • Anti chafe polyurethane head bumper.
  • Fixed head webbing for easy insertion of mast without fussy head plug alignment.
  • Increased boom cutout depth aids boom attachment.
  • Zippered neoprene cutout closure.
  • Full framework of Kevlar unidirectional reinforcement
  • Race level clew cutaway.
  • Lightweight clew fitting with easy rigging loop feature.
  • Seam and foot beads for chafe protection.
  • Tough tack and sleeve anti-chafe material
  • Roller wheel cams with asymmetric shape.
  • Welded stainless steel and bronze triple wheel tack pulley.
