Interview / Plume 2.0: Gildas Plessis reimagines his transportable day boat

Nearly 30 years after the first sketches of the Plume, architect Gildas Plessis unveils a completely redesigned version of his transportable dayboat. While the concept remains unchanged, the design has been overhauled from top to bottom. The hull, materials, structure, and sail plan have been updated to meet current expectations. An interview with an eclectic, multi-talented architect.

The Plume is one of those sailboats that are instantly recognizable. Designed by architect Gildas Plessis in the late 1990s, this 6.10-meter transportable catboat has made its mark on many French sailing waters. Twenty-five years after the launch of the first prototype, the Breton architect now presents the Plume 2.0, a complete evolution that retains the project?s founding concept while incorporating several decades of reflection on naval architecture.

A concept that has stood the test of time

Before becoming a production boat with some 40 units built in Bordeaux between 2001 and 2013, the Plume was initially a prototype constructed from composite sandwich panels with a rotating carbon-fiber mast.

The production model, recognizable by its laminated wood boom, quickly found an audience. Even today, there are still many of them in the Gulf of Morbihan, on Lake Geneva, and in the Arcachon Basin.

For Gildas Plessis, the goal was not to replicate the original boat.

"This isn't a reissue. We're starting from scratch with a concept that's nearly 30 years old. The idea wasn't to build the same boat again, but to update everything we envisioned back then using the tools, materials, and knowledge we have today." , explains the architect.

The catboat remains at the heart of the project

Despite this complete redesign, the catboat concept remains intact. The Plume 2.0 is still available in its traditional single-sail configuration, but it can also be fitted with a sloop-style Marconi rig.

"The catboat concept remains hugely popular. It offers an open cockpit, minimal rigging, and is incredibly easy to handle. It?s a boat that makes you want to get out on the water right away, without spending time setting up the rig." , Gildas points out.

This day-boat philosophy remains at the heart of the project. The boat is still trailerable and designed for coastal or lake outings, where ease of use is often a key factor.

A new hull design inspired by modern sailboats

The most noticeable change is to the hull. The Plume 2.0 now features a more voluminous hull shape and a bow inspired by scow-type hulls. The forward sections are more pronounced, and the overall length has increased by 10 centimeters.

"We chose a modern hull design with a pointed scow shape. It offers greater stability, more power, and better overall performance while retaining the spirit of the original boat." , explains the architect.

The appendices have also been redesigned.

"We've incorporated solutions developed through our work in ocean racing. This mainly concerns the hull profiles and hydrodynamic balance. Even on a day boat, these details have a direct impact on the boat's performance."

A design that does away with polyester

Evolution isn't just about form. For this new generation, Gildas Plessis wanted to completely rethink the design approach.

"If we want to move toward low-carbon construction, it becomes difficult to continue using polyester on a large scale. We have therefore been working on a sandwich structure that combines natural fibers and basalt, among other materials."

Basalt is now used in a variety of marine applications as an alternative to certain traditional fibers. When combined with flax, it helps reduce weight while maintaining high mechanical properties.

"The industry's current recommendation is clearly to prioritize basalt where appropriate. This allows us to achieve a lighter and stiffer structure than on the production boat built twenty-five years ago."

More fabric for summer conditions

The sail plan has also been updated. The sail area has been increased to improve performance in light winds.

"The catboat performs very well, but it can sometimes lack a bit of power in calm conditions. So we increased the sail area and added a small jib to improve performance in light winds."

This development is primarily designed for the most common sailing conditions for this type of boat: summer day trips, which are often characterized by moderate winds.

Even though the boat is new, several features pay homage to its predecessor. The deck layout has been completely redesigned, and special attention has been paid to certain lines of the furnishings.

"We?ve retained a few nods to the original Plume. The seats, in particular, have been highlighted to create a visual connection with the historic boat while establishing a much more contemporary identity."

This design approach is complemented by an ergonomic redesign intended to make it easier to move around and maneuver on board.

SailWood is building the next generation

The construction of the Plume 2.0 has been entrusted to the SailWood shipyard in Lorient. The company was not chosen at random. For several years now, it has been responsible for the maintenance, repair, and restoration of existing Plume boats.

"SailWood knows the boat inside and out. They've been maintaining many of them for a long time. It was a no-brainer to entrust them with building this new generation." , says Gildas.

The first production model is scheduled to enter construction in the summer of 2026. For the naval architect, this new model represents continuity rather than a break with the past.

"The Plume has always been a pleasure boat?simple, lightweight, and easy to transport. This concept remains as relevant as ever. We simply tried to bring it up to date."
