COR52 hull and propulsion

The hull has been designed so that the yacht is very effective in the range of 7-10kts.
Changing times and user trends have influenced the design of the hull, which has the ability to move faster. The most common reason is escaping to a port to escape bad weather and limiting time in open waters when traveling, e.g. between islands.
That’s why we give customers the opportunity to choose between several drive systems. The largest of them, 2x400Hp, allows you to achieve 14kts.

The drive configuration is a typical twin system.
It ensures quiet operation and excellent maneuverability.
This system is fully redundant.

To minimize maintenance needs, we recommend a keel cooling system and a dry exhaust system.
In this case, to reduce smoking when starting a cold engine. The engines are equipped with engine block heaters. This solution additionally reduces the wear of an underheated engine.

It is possible to order a yacht with one main engine located centrally and a wing engine with a lower power.
This solution will slightly lower operating costs.

The drive of a yacht sailing around the world must be easy to operate. Consumable parts are easily available and inexpensive. Widely available service and engines known everywhere.
Engines should meet exhaust emission standards around the world.
That’s why we chose JOHN DEERE engines and ZF transmissions.
We focus on two engine families
JOHN DEERE 4,5L 6.8L
Each engine can be selected in the rating M1 to M4.
We recommend 150hp and bigger set 230Hp for the 6.8L engine. This will allow for greater system efficiency at speeds of 7-10kts.

The shaft line is angular with an inclination of 8°-10° and a four bladed propeller with a diameter of 40″
ZF 85A series gears, gear ratio i=2.5
propeller rotation speed at 7kts.
