Mauisails Carbon Booms

The state of the art carbon booms

Mauisails Carbon Booms


It's been many years with the graphic unchanged and along the way we have been continuously improving small details. The adjustment clips have gone through a big evolution to prevent the corrosion that affected them (we had to chrome plate the 316SS pins!), and the clip bodies were made stronger as well. 

Small adjustments to the layup and material specs were made for the Race 190-240, and for this year, there is a wide tail slalom version of the Slalom 170-230 (the tail piece retrofits both the Wave 170 and 140). The new grip design is a 'statement' for 2012, and also has less pieces and a slightly harder character to improve durability. 

So the boom is 'new' in a sense, but it is still the same old super strong, stiff, perfectly shaped one you might have known before.

Using moulds developed and owned by MauiSails, and designs with unique bends and diameters, assures that our full range of carbon booms is exclusive to MauiSails in every regard. All plastic parts are designed, developed, and molded to create these special products, the recognized highest standard of carbon booms in the windsurfing industry today. 

Huge steam heated press moulds are the core of the complex process. These state-of-the-art carbon booms are formed using pre-preg carbon fiber to produce the best weight to stiffness possible in composite carbon construction. The tested and proven proprietary frontend is designed to perfectly mate with the 40mm diameter monocoque boom arm. Each boom size is purpose specific, from the Carbon Race 250-310 with large diameter tubes and continuous tail piece with built-in adjustable outhaul pulley system, to the Wave 140 with full length 30mm grip for super hand comfort and control.

Technical features

  • High Stiffness to Weight with double tapered tubes. Race booms are 40mm at the front and back, with 35mm diameter backends, and are the stiffest in the industry.
  • 50 - 60 cm length adjustment covers a large number of sail sizes.
  • Smaller 30mm diameter of the wave booms makes for comfortable grip.
  • Monocoque Construction in Pre-Preg Carbon for maximum stiffness and durability.

  • Included Adjustable Outhaul kits and Wide Tail backend with Race booms and Carbon Slalom 170.
  • Redesigned Double Pin Rear End Clips increase durability, stiffness and torsion rigidity.
  • Molded Precision produces perfect tolerance between the Boom Body and Rear End for smooth and easy adjustment.
  • High Performance grip surface is durable and easy on the hands.
  • THE TEAM tested and approved Boom Arm Curves and Overall Width (Arm to Arm distance) maximizes sail performance.

MauiSails Boom Front End

A good boom is much more than some carbon tubes

MauiSails Boom Front End


A good boom is much more than some carbon tubes. The key elements of the whole system are also the length adjustment locking parts, and the boom head that attaches to the mast.

The design of boom heads has undergone regular evolution, but much of it is far behind the development of the larger rigs. So the result is that you may have a pretty good set of tubes that may be stiff and strong enough for the larger sail, but they are connected to an older design head that isn?t. This will make you have a wobbly connection regardless of the stiffness of the tubes.

When we conceived and designed the new MauiSails Carbon Race booms, the shortcomings of the available head designs (as well as the good things) were considered. We wanted a unique and durable head to go on these great products.

Using Rapid Prototyping we were able to see the functioning part direct from tooling drawings, in one off versions that only took a week to execute. This let us play with the levers, cleats, and other relationships without having to wait months for tooling to be finished. And we could see potential for failures and correct them as well.

There are potentially thousands of active sailors with carbon booms from many manufacturers who will appreciate the value of this quality upgrade. The MauiSails Boom Head is simple and inexpensive to retrofit and will make almost any set of boom tubes seem like a whole different experience.

Only low pressure required here

The MauiSails boom head and clamping lever is designed to be used with the MINIMUM tension required to keep it from slipping on the mast. DO NOT OVER-TIGHTEN or you will risk damaging the part.

All metal parts are subject to corrosion. To keep your boom and its small metal parts in top shape it is recommended to thoroughly rinse with fresh water after each use, especially the tail clips and pulley assemblies.

Please remember if you are going to use our boom head with RDM mast you will also need a boom shim dedicated for MauiSails Front End.
