Esse 850 Information, Review, Specs

The creation of the Esse 850 in 2004 was the result of a deliberate collaboration between Proteus Yachts and Umberto Felci, initiated by Josef Schuchter. The core concept was to develop a sporty boat that combined simplicity with speed, offering above-average sailing characteristics while remaining easy to handle. Proteus Yachts, known for its focus on high-quality, performance-oriented sailboats, brought its manufacturing ethos to the project, utilizing advanced materials such as fiberglass with an epoxy and Vinylester resin system and a sandwich core for optimal lightness and structural integrity.

Over its production run, the Esse 850 has seen some evolution. In 2015, the Esse 850 LE was introduced, aiming to provide improved handling and comfort, distinguishing itself as an "elegant daysailer". There is also mention of an Esse 850 L variant with a shallower draft of 1.50 meters compared to the standard 2.00 meters. The boat features a lifting keel designed to reduce the overall towing height, a practical consideration for trailerability.

Sailing Performance and Handling

The Esse 850's design ratios underscore its performance-oriented nature. With a Sail Area to Displacement ratio of approximately 31.05, it boasts excellent light-air performance, suggesting it can ghost along in minimal breeze. Its Ballast to Displacement ratio, around 0.555, indicates significant stiffness and stability, allowing it to stand up to more wind and maintain its sail plan effectively even in challenging conditions. Furthermore, a Displacement to Length ratio of about 155 signifies a light, nimble, and performance-focused hull.

Anecdotal reports consistently praise the Esse 850 for its dynamic and responsive handling. It is often described as having perfect light wind characteristics and demonstrating functionality across a wide spectrum of wind and wave conditions. The boat's balance and straightforward behavior contribute to its reputation as being "fast, technical, safe and easy to sail," appealing to those who seek exhilarating performance without overly complex handling. Its deep lifting keel, with a maximum draft of 6.56 feet, contributes to its upwind prowess and stability.

Accommodations and Layout

As a sport keel monotype primarily designed for daysailing and racing, the Esse 850 features a minimalist but elegant interior. While specific details on the internal layout are limited, the design prioritizes sailing functionality over extensive cruising amenities. Reviews suggest it typically includes a single guest cabin, emphasizing its role as a race-focused vessel or a comfortable short-term cruiser rather than a liveaboard. The interior is generally understood to be well-finished, reflecting the builder's commitment to quality, even if the primary focus is not on luxurious living spaces.
