Understanding Sail Lifespan: Performance vs. Physical Durability

Understanding Sail Lifespan: Performance vs. Physical Durability Every sailor knows that sails do not last forever. However, when we talk about the “lifespan” of a sail, we are actually discussing two very different concepts: the physical lifespan and the performance lifespan. Understanding the distinction between the two, as well as the underlying factors that cause […]

Now, it is time to […]

Offshore Sail Care: Protecting Your Engine on a Bluewater Passage

Introduction When you are a thousand miles from the nearest sail loft, your sails are your most vital piece of safety equipment. They are the engine that drives your catamaran across oceans.

Chasing the Trades: Code Zeros and Asymmetrical Spinnakers for Catamarans

Introduction Bluewater cruising often evokes romantic images of sailing bareheaded before the trade winds for days on end. However, the reality of downwind sailing on a large catamaran can sometimes be frustrating if you do not have the right sail inventory.

The Great Debate: Self-Tacking Jibs vs. Overlapping Genoas

Introduction If you walk the docks of any major boat show today, you will notice a distinct trend among modern cruising catamarans: the overwhelming popularity of the self-tacking jib. As multihulls have grown larger and more luxurious, builders have prioritized ease of handling for short-handed, often older, cruising couples. But is a self-tacking jib the […]

Reefing a Catamaran Mainsail: Systems, Safety, and Best Practices

Mastering Sail Twist: The Secret to Catamaran Mainsail Trim

Introduction Sailing a large catamaran offshore is an exercise in power management. Because a multihull does not heel to spill excess wind, all the force generated by the sails is transferred directly into the rig and the hulls. Understanding how to control and manipulate this power is the hallmark of a skilled bluewater cruiser. The […]

Headsail Sheeting and Spreader Clearance on Catamarans

Introduction One of the defining characteristics of a catamaran is its immense beam. While this width provides incredible stability and living space, it fundamentally changes the geometry of the rigging and how the sails are trimmed. When designing a new headsail for a bluewater catamaran, two of the most critical factors we must consider are […]

Measuring a Catamaran for Sails: Avoiding the Common Pitfalls

Introduction Ordering a new set of sails is an exciting milestone for any bluewater cruiser. However, before the first panel of cloth is cut, precise measurements must be taken. While the basic principles of measuring a sail (Luff, Leech, and Foot) apply to all boats, catamarans present a unique set of challenges that can easily […]

Square-Top Mainsails: Ultimate Performance for Cruising Cats?

Introduction If you have watched any modern multihull racing—from the America’s Cup to the SailGP circuit—you have undoubtedly noticed the distinctive, flat-topped mainsails. These are known as square-top (or flat-top) mainsails. Over the last decade, this aggressive design has trickled down from grand-prix racing into the performance cruising catamaran market. But does a square-top mainsail […]
