About the Boat
The concept of simplicity combined with speed was the requirement which Josef Schuchter confronted Umberto Felci with. The Esse 850 should be sailed easily single-handed or by a small crew at fast speed without the ship heeling much. Umberto Felci realised this idea magnificently. Due to the fact that the ship has a high ballast ratio and good strength of shape, the Esse 850 has a very large righting moment. This is why the Esse 850 is very stable and secure.
Further Details
- The Esse 850 was voted « boat of the year » in Europe (2005) and in the USA (2007)
- No running backstay
- Gennaker instead of spinnaker
- All trimmappliances are within reach of the cockpit
- A suit: Main, Jib, Gennaker (no Genoa)

About The Class
The «Esse 850 International Class» is the official class-unification of the Esse 850 One-Design yachts and was founded in January 2007 at Schloss Rapperswil. Its task is to enable international regattas, stimulate communication among the sailors of the Esse 850 and promote and coordinate all activities in Switzerland and internationally.
In 2010, the Swiss Esse 850 Class was accommodated to «Swiss Sailing» as a Member Class and has been authorized to perform official Swiss Championships. The class association currently counts 50 members who actively participate in regattas.

Esse 850 is a 27 ′ 10 ″ / 8.5 m monohull sailboat designed by Umberto Felci and built by Proteus Yachts and Schuchter Sportboot starting in 2007.
Rig and Sails
Auxilary power, accomodations, calculations.
The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL
Sail Area / Displacement Ratio
A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.
SA/D = SA ÷ (D ÷ 64) 2/3
- SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
- D : Displacement in pounds.
Ballast / Displacement Ratio
A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.
Ballast / Displacement * 100
Displacement / Length Ratio
A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
- D: Displacement of the boat in pounds.
- LWL: Waterline length in feet
Comfort Ratio
This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )
- D: Displacement of the boat in pounds
- LOA: Length overall in feet
- Beam: Width of boat at the widest point in feet
Capsize Screening Formula
This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.
CSV = Beam ÷ ³√(D / 64)

Esse 850: 2007 Overall Boat of the Year
- By Tony Bessinger
- Updated: January 5, 2007
In the world of yacht racing, aesthetics took a back seat to design a long time ago. As a result, there are few boats out there today that make people stop and stare. But at the United States Sailboat Show this year there were a few boats that drew our attention. One in particular was the Esse 850, a 28-foot sportboat that’s not only drop-dead gorgeous, but a thrill to sail as well.The Esse, designed by Umberto Felci and built by J. Schucter Yachting, is first and foremost a gentleman’s performance daysailer. It’s a legs-in one-design with a narrow 7’6″ beam and a keel bulb that far outweighs the hull. “At first glance, the boat looks incapable of supporting its large sail plan,” says BOTY judge Meade Gougeon. “The reality is that it’s a 2,500-pound boat with 1,500 pounds of that weight six feet below the waterline. As a result, it’s surprisingly stiff.” The Esse’s stiffness was borne out in our test sail, which took place in puffy, 10-knot conditions. We were impressed with its performance, how easy it was to rig and sail, and how much fun we had sailing it. Upwind, it locked into a groove, and steering the well-balanced boat required only a fingertip grip. The underdeck-mounted headsail furler adds to the ease of shorthanded sailing and brings the foot of the sail close to deck level, which no doubt helps the boat’s impressive upwind performance.Once we had the 860-square-foot gennaker flying, the boat really came to life. “The helm is well balanced,” says Andrews. “Put it on a tight reach and the foot of the spinnaker will drag in the water quite a while before the rudder stalls. The boat turns well and jibes easily, which is not always the case for sprit boats. It’s really easy to get the timing right so that you come out of the jibes with the kite popping full.”Even Gougeon, a self-proclaimed multihull fanatic embraced the Esse. “It’s a ballasted monohull sportboat that I can actually get excited about because of its unusual off-the-wind potential,” he says.To only tout its performance on the water would neglect the Esse’s full package. The boat was introduced in Europe in 2004, so the model we sailed in Annapolis is the result of two years of refinement. “This is a polished package where all the parts seem to work well,” says BOTY judge Alan Andrews. “Details such as the notch in the cockpit seat, which holds the ball end of the tiller extension and locks the tiller in the center of the boat for a quick, short-handed kite hoist or dowse, is an example.”The Esse’s construction isn’t all that high-tech; it’s built with epoxy, foam core, and E-glass in Italy, then finished by Schucter in Switzerland. The quality of the construction is outstanding, as one can see down below. The Esse’s interior, while minimal, is elegant and finished nicely. There’s a platform forward that, once cushioned, will work well as a V-berth, and there’s room for sail and gear stowage as well as a port-a-potty.On deck, the Esse is all about ergonomics, style, and details. All control lines lead aft under or on the low, sleek deckhouse. The mainsheet and traveler are forward of the tiller, and the cunningham, and backstay controls exit from a low box on centerline that also acts as a foot brace. All control-line tails disappear into the vertical faces of the cockpit seats through beveled stainless-steel plates, and bungee cords take up slack. The optional teak floor in the cockpit looks good and feels great underfoot. The Esse we sailed came with a 2-horsepower outboard, which mounts on a removable stern bracket, and is stowed low in the boat in a cavernous centerline storage area under a hatch in the cockpit floor. There’s an option for a diesel/saildrive power package (the boat comes standard with the engine footings built into the hull), but all judges felt the outboard did the job well, and liked the idea of keeping the boat simple.The rig is aluminum, as is the boom. “It works well,” says Andrews. “The easy-to-adjust backstay and natural twisting ability of the square-top main combine to rapidly power up and depower the rig in the gusty conditions.” The rig is deck-stepped, with a compression tube below. The spinnaker pole, which exits on the starboard side of the bow, is carbon, and the sprit pole casing, which is watertight, drains out the topsides via a flush exit.BOTY judge Chuck Allen’s paean to the boat is the one that resonates best. Allen, a former All-American who’s also spent a lot of time racing small keelboats, sums up the Esse succinctly, and explains why the judges chose it as their overall winner. “The Esse 850 is one of the best sportboats I’ve ever sailed,” says Allen. “It’s quite simple, it’ll be easy to singlehand, and it’s easy on the eyes. This is the perfect boat to sail in your Tuesday night series or a venue like Key West Race Week.”
