ENGINEERED FOR PERFORMANCE

The Future of Continuous Membrane

True continuous fiber technology. No glue. No seams. No delamination.
Just pure, uninterrupted load paths from corner to corner.

LoadX vs 3Di

Two paths to membrane technology. One focuses on weight, the other on longevity.

3Di North Sails

LIGHTWEIGHT
⚠️ Glue points concentrate stress

Short Fiber + Glue. 3Di excels at weight reduction by bonding short filaments. However, these bond points are structural "circuit breakers" that degrade over time.

  • Cannot be repaired by local lofts
  • Delamination risk after 5 years

LoadX Technology

DURABLE
✓ Uninterrupted load path

Continuous Fiber. A single strand runs corner-to-corner. No glue points to fail. The fiber carries 100% of the load, while the film only protects.

  • Repairable at ANY sail loft
  • 8+ Year lifespan guarantee

Why Choose LoadX?

  • Club Racing 95% of the performance of 3Di for half the depreciation cost.
  • Offshore Cruising Repairable anywhere in the world. No factory shipping needed.

The Truth About Weight

vs

LoadX is 10-15% heavier than 3Di.

If you are an Olympic campaigner, buy 3Di. For everyone else, that extra weight buys you 3 extra years of life.

Why Choose 3Di?

  • Grand Prix Racing When budget is unlimited and every gram counts.
  • Sponsored Campaigns When you can afford to replace sails every 2 seasons.

The Exoskeleton Structure

Separating load-bearing from protection. Just like nature intended.

Layer 1Structure
Layer 2Load Path
Layer 3Taffeta Skin
Hover to Explode

Like Reinforced Concrete

In skyscrapers, the steel frame carries all the weight, while concrete only provides protection.

LoadX applies this same engineering principle to sails.

1

Fiber = Steel Frame

Continuous fibers carry 100% of the wind load. They never stretch, they never creep.

2

Film = Concrete Shell

The outer skin only protects against UV, water, and chafing. It carries zero load.

"By separating these duties, we eliminated the #1 cause of membrane failure: film fatigue."

LoadX vs 3Di: Performance under load

3Di - Short Fiber + Glue

← Pull
Pull →
Short Fibers
Glue Points
Stress Concentration → Glue Failure
  • Short fibers connected by glue
  • Stress concentrates at glue points
  • Glue degrades (heat, UV exposure)
  • Micro-gaps appear between fibers

LoadX - Continuous Fiber

← Pull
Pull →
Continuous Fiber (Uninterrupted)
Even Stress Distribution → No Failure Risk
  • Corner to corner, one uninterrupted fiber
  • Stress distributes evenly across entire fiber
  • No glue, no failure risk
  • Maintains integrity, 8+ year lifespan

Who is LoadX For?

The smart choice for reliable performance.

Professional Training

For teams that need grand prix performance styling but cannot afford to replace sails every season due to training wear and tear.

  • Rugged durability
  • Shape retention
Best Value

Club Racers

The sweet spot for Saturday regattas. Competitive performance against any fleet, with a lifespan that makes sense for your wallet.

  • 95% performance of 3Di
  • Half the long-term cost
  • Easy local repairs

Blue Water Cruising

Lighter sails mean less heeling and faster passages. Reliability means you sleep better at night knowing your gear won't fail.

  • Global repairability
  • UV Shield protection
