Real-World Test: How Our New Carbon Front Beam Handled a Choppy Sea

Author: Shayne and Anna

Key Message: This sea trial proved that true performance isn’t just about strength or weight savings, but about how upgrades transform the sailing experience in real-world conditions. Despite the inevitable “breakdowns” that accompany any major refit, the immediate and tangible improvements—a stiffer, more balanced boat, easier speed, and transformed steering—validated the entire project, turning a messy, choppy day from a slog into a genuine blast and proving the carbon beam’s worth not in a lab, but on the water.

The installation was complete, but the real question remained: how would our new carbon fiber front beam and longerons perform on the water? We didn’t need a gale to find out; we just needed a typical, imperfect day. This week, we found the perfect conditions for our first sea trials—a “lumpy and messy” sea state that provided the ideal real-world stress test.

It wasn’t all smooth sailing. Our shakedown cruise was a classic blend of breakthrough and breakdown, featuring a last-minute sail repair and the persistent nuisance of diesel bug.

The Midnight Sail Repair

No major upgrade is complete without a cascade of smaller adjustments. For us, it was the mainsail.

Our initial placement for the head webbing was too low for the new rig, causing the cunninghams to sit incorrectly. The solution seemed simple: move the webbing up. What we thought would be a “quick five-minute job” turned into an all-night marathon.

By 2 a.m., we were battling a temperamental sewing machine. By 4 a.m., the stitching was finally done. After a few hours of sleep, we were painting the repair and finishing the leech line by hand. The boat was ready for its test.

The Carbon Beam in a Choppy Sea

We motored out into the “floppy choppy” waves—not storm conditions, but unpleasant and messy enough to reveal any weaknesses. So, how did the new carbon setup hold up?

The improvement was immediately noticeable.

  • Transformed Steering: The first comment from the helm was, “Rudders are a big improvement… it definitely steers better.” The boat felt more connected and responsive.
  • A More Balanced Boat: Under sail, the boat felt fundamentally more balanced. “It definitely sails better… the boat feels more balanced,” was the verdict. The carbon rig provided a stiffness that translated into smoother handling.
  • A Clear Speed Gain: The most exciting result was the speed. Sailing downwind, we were able to drag the apparent wind forward by about 30 degrees—a clear sign of a more efficient and slippery hull. Hitting 10 knots felt easy and sustainable.

The takeaway? A trip that used to take six hours now promised to be significantly faster. The upgrade had turned a slog into a blast.

Lessons from the Shakedown

A successful test always reveals the next items on the list. We noted two key upgrades for the future:

  1. Non-Skid on the Beam: The sleek carbon surface is effective but can be slippery. Adding non-skid tape is a must for safe foredeck work.
  2. Rudder Winglets: To further dampen any hobby-horsing in a chop, we plan to add winglets to the rudders.

3D Printed Rudder Winglets

We’re in the middle of a huge project to make our catamaran, Paikea, lighter, so you might be wondering why we just added a heavy 23kg 3D printer to the boat. For us, it’s a powerful tool for creation. We’re using it to design and print custom parts that we can’t easily buy, like our new rudder winglets.

The printer allows us to create the perfect adjustable plastic core for each winglet, which we will then laminate with epoxy and fibreglass cloth to make strong, lightweight, and efficient hydrofoils. So, while the printer itself has some weight, it enables us to build specialized components that will ultimately enhance our boat’s performance.

The Verdict

After an overnight sewing saga and a day contending with diesel bugs and choppy seas, the results were in. The carbon fiber front beam and longerons were a resounding success. The boat is stiffer, faster, and more responsive, making typical, messy conditions not just manageable, but genuinely enjoyable.

It’s these moments—when a tough project culminates in a clear performance win—that make all the hard work of boat life worthwhile.
