Privilege 580
Participate in the Dave Score:
Welcome back to Naval Gazing at Camp David.
This week’s guest yacht is from a storied French brand, whose fame has been re-kindled more recently through the exploits of the You Tube family on Sailing Zatara. Purchased by Hanse in 2019, Privilege has launched a new version of Zatara’s beautiful 585…
The new Privilege 580!
For our wine pairing this week we move inland, North East to Le Puy-Notre-Dame and Manoir De La Tete Rouge.
Manoir De La Tete Rouge Samur Bagatelle Cabernet Franc is our pairing.

• Integrel Solutions:
o The Integrel Generator, which is fitted to each engine of your Cat, generates energy seamlessly under normal operation. Your existing engine has a significant amount of spare capacity, Integrel harnesses this spare capacity to generate electrical energy to be stored for later use; all while keeping your engine running at optimum performance.
o Integrel exploits the fact that there is a significant power gap between the optimum efficiency load line of an engine and the load applied by the propeller (the green and blue lines respectively in the following diagram). The generator is used as a precisely managed variable load in addition to the propellor load to operate the engine at or near optimum efficiency. The result is one engine doing two jobs: turning the propeller and generating electricity, with both tasks delivered with the best possible fuel efficiency to save fuel.
o Since boat speed is locked to propeller speed, with a well governed modern engine, adding the generator load does not change the boat speed. As a practical example, at a cruising speed of 1700 rpm with a typical 60 kW engine, the propeller load is about 8 kW and the optimum engine load is about 22 kW, leaving 14 kW excess power. At this speed, the Integrel generator produces 8 kW of electrical power and applies around 11kW of mechanical load on the engine, moving the total engine load into the optimum operating area.
o Integrel generates up to 18kW of energy with a dual system on a catamaran and improves the fuel efficiency of the propulsion engine up to 25%, reducing overall vessel fuel consumption. It is fully automatic, managing electrical power generation, storage, conversion and distribution in one package.
o The Integrel Intelligent Controller converts raw electrical energy from your engines into usable energy at 48 volts. Energy production is closely monitored by sensors on each battery bank to keep the batteries safe. The stored electrical energy is then used to power heavy-duty 48 volt items such as bow thrusters and winches, as well as 12 volt domestic items like your fridge, instruments and house lights and 110 volt or 240 volt AC devices like air conditioning, washer, freezer etc.
o The primary difference between Integrel and a Mastervolt system is sustained output. The Mastervolt alternator is a standard design high performance
alternator. They do deliver a high output for a short period of Time, but as soon as they warm up they derate to 1/3 of their peak rate performance.
o The integrel generator has been optimised to do the following
Software limited at 9kW
Sustained output ~8kW+
Diode pack and other sensitive electronics have been removed to the Intelligent controller
Removing the electronics allows better airflow and cooling, as does the large frame design
The Intelligent controller
• can determine if the boat is in gear or neutral and adjusts accordingly
• Can be programmed to provide very high output at low RPM
• Can be programmed to charge Lithium Ion batteries per a custom charge profile
• Charge algorithms are altered by
o Engine HP
o RPM
o Temperature
o Engine power curve v propellor power curve
o The Mastervolt alternator comes as is with very little flexibility regarding configuration for the above parameters.

Patrick Briere
Village Breton
Patrick Briere’s artistic path tends towards the simplification of forms, bordering on abstraction, with an almost fauvist-inspired harmony. The French painter’s compositions are colorful evocations of a fleeting moment. As a result of this constant searching, Briere’s paintings are by no means ‘frozen’. Color and light are vital elements of the identity of his pieces, which he translates through oils, acrylics, charcoal, and pastels.
