Profile depth of sails
For each winter and ice conditions we have different racing sails. Basic parameters for sails is profile depth. The following table shows comparison of designed depth measured in % (100% is basis value for Vector STANDARD):
| |
Sail |
Profile depth |
Vector MAX+ |
125 % |
Vector MAX |
112 % |
Vector STANDARD |
100 % |
Vector SUPER+ |
91 % |
Vector SUPER |
79 % |
Vector FLAT+ |
69 % |
Vector FLAT |

Vector Opti-MAX |
125 % |
Vector Opti-STANDARD |
100 % |
Vector Opti-SUPER |
75 % |
Sails: Vector CRUISING and Vector Opti-CRUISING have depth equal 100%. It means that these sails are type STANDARD for profile parameters.
DN battens stiffness
For each individual DN racing sails we have special designed set of battens. Battens stiffness is measured in kilograms according to figure in table below:
