Broker's comments

This Cosinus Alu 50 sailing boat is perfectly adapted for the BLUE WATER PASSAGES with very complete equipment in good state. She is a fast sailing boat in small weather, of exceptional reliability in big seas. Her performance and upwind stability are extremely valuable on long trips. Her hydraulic equipment and deck plan and the ergonomics of the cockpit, make the Cosinus Alu 50 a handy sailboat without any problem alone or with reduced crew.
