Racing Upwind Sails

Cross-Cut Woven Polyester

Cross-Cut Sail Construction

Quantum's woven polyester mainsails and headsails (RW 1000) set the standard for cross-cut construction, bringing an unmatched level of refinement and attention to detail to the basic workhorse of the racing inventory. Durability, ease of handling and performance are equally weighted design criteria.

Designed for Maximum Control

When it comes to boat handling and speed, it's sail shape that makes the difference. Sail shapes are custom-designed for your boat by Quantum’s experienced sail designers based on expected usage and boat-specific constraints such as mast bend, displacement and righting moment. Sail shapes feature a smooth, flat aerodynamic profile for optimum upwind performance, with an open trailing edge to reduce heeling and weather helm.

The Right Materials for the Job

Woven materials for racing sails differ from their cruising counterparts based on the amount of resination. The firm, crisp feel, and the load noise of a luffing sail are characteristic of the "yarn tempered" finish found in racing woven materials. Quantum’s woven sails are made using only the highest quality, tightly woven, and most stretch resistant woven polyester available. Minimizing stretch is the key to creating a durable sail with exceptional shape holding. All woven materials are not created equal; there are variations in yarn type, thickness, weave and finish. We test and use only top-grade sailcloth, appropriate to the application, selected from the best that leading suppliers have to offer. Quantum's sailcloth is tested in-house. This allows Quantum to not only use the very best, but also make sure the fabric is appropriate to the application.

Built to Take On the Toughest Racing Conditions

Quantum's woven polyester racing mainsails and headsails deliver long-lasting performance. Our modern, cross-cut construction features panels joined with extra wide seams, using a combination of adhesives and multiple rows of triple-throw stitching, with additional "butterfly" reinforcements at both the inboard and outboard ends. See more construction details below.

Sail Construction Details

When it comes to sail quality, small details make a big difference. Excellence and attention to detail are hallmarks of every Quantum® sail and ensure reliable performance. Click on photos for more information.

Headsail Clew

Racing headsails feature our “T” ring clew fitting with cover for the ultimate in clean, low profile sheet attachment.

Mainsail Clew

Quantum’s racing mainsails feature a lightweight stainless steel ring in the clew with multiple webbings, Velcro® clew strap and extensive “quilting” for smooth, clean handling of the sail’s most highly loaded corner.

Headsail Clew

Leech and foot cords on our headsails utilize multiple purchase for easy adjustment and protective covering.

Headsail Tack

The tack on our racing jibs features a lightweight, webbed-in stainless steel ring. Stiff, extensively quilted Dacron® patching provides smooth transfer of corner loadings into the body of the sail. ISAF certification so you can be sure your sail measures in.

Leech Cord Detail

The leech cord with sewn aluminum cleat and shock cord take-up system provides smooth, simple adjustment.

Mainsail Tack

The mainsail tack features a lightweight, webbed-in stainless steel ring, webbed cunningham, foot cord and overhead leech cord for easy access and adjustment.

Mainsail Batten Pockets

The batten receptacle and Teflon®-reinforced luff tape at the inboard end of full length battens ensure smooth batten-to-mast connection and reduce friction and wear over time.

Mainsail Leech Reef

Racing mainsail leech reefs feature lightweight Spectra webbing and separate leech cord access supported by heavily quilted Dacron® patching to smooth the transition into the body of the sail.

Mainsail Luff Reef

Racing mainsail luff reefs feature lightweight webbed-in stainless steel ring anchored in layers of heavily quilted Dacron® to ensure smooth transition into the body of the sail.

Mainsail Leech Battens

Mainsail leech batten with RBS rocket tensioner provides easy adjustment and a smooth, low profile cover to prevent batten from hanging up on the backstay.

Mainsail Head Details

Quantum’s racing mainsails feature a lightweight, aluminum headboard with overhead leech line for easy access and ease of adjustment. Quilted, extra-stiff Dacron layers provide smooth transition of loadings into the body of the sail.
