Headboard with special designed shape for easy trimming of leech tension. Long bag for rolled sail. Class insignia. Four pocket battens. Clew slider made of hardness steel with plastic cover. Sail fulfill requirements of DN class rules.

DN cruising sail

Soft polyester sailcloth. One window with soft mono-film resisted to wrinkles. Headboard with special designed shape for easy trimming of leech tension. Bag for folded sail. Class insignia. Four pocket battens. Clew slider made of hardness steel with plastic cover.

Ice Optimist racing sail

Sailcloth Ripstop Pentex Contender. Windows with hard mono-film. Two battens on the leech. Cotton telltales on the sails and the leech. Speed strap. Long bag for rolled sail. Class insignia. Sail fulfill requirements of Optimist class rules.

Ice Optimist cruising sail

Soft polyester sailcloth. Two battens on the leech. Bag for folded sail. Class insignia. Sail fulfill requirements of Optimist class rules.

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	57 %
–	–
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:

Sail	Set of battens
Vector MAX+	MEDIUM
Vector MAX	MEDIUM
Vector STANDARD	STANDARD
Vector SUPER+	HARD
Vector SUPER	HARD
Vector FLAT+	HARD
Vector FLAT	HARD

Stiffness of each batten is measured in kilograms according to figure in table below. Approximating value of batten force shows table below:

Batten	MEDIUM	STANDARD	HARD
Long up	2,3 kg	2,5 kg	3,1 kg
Long middle	1,7 kg	2,1 kg	2,8 kg
Long down	1,4 kg	1,6 kg	1,9 kg
Short	2,2 kg	2,2 kg	2,2 kg
