This trimguide is based on the expertise of Sari Multala, 2001 World champion and for ease of use is divided into seven wind strengths. For further information, including Mast rake basics, visit WB-Sails.

0-2 m/s (0-4 kn)

In very light airs you want to keep the sail leech as "soft" as possible and favour speed for pointing.

The Sheet should be loose, with the boom 15 to 30 cm above the deck.

The traveller is set so that the boom end lies between mid tank and the corner of the transom.

Inhaul: loose, 5 cm from mast

Cunningham: loose

Outhaul: loose, 5-8 cm from the maximum tension. Max. tension may well be 3-4 cm off the mark - the foot of the sail is a little shorter.

Centerboard: straight down

Mast rake: in "base position", approximately 545 cm for a short leech sail (SL) and 555 cm for the long leech sail (LL)

In light airs you want to keep the cunningham loose. Never mind the wrinkles - the shock cord in the luff lifts the cunningham up giving fullness and extra power to the sail.
