North Northwest Thistle Mainsail
Because of the use of firmer fabric and the Northwest Mainsail features a slightly rounder leech, and is a slightly more mainsheet-sensitive sail. It is also a flatter main, note with the draft farther aft and a relatively closed leech.
Fast, the Northwoest mainsail excels especially on flat water, and has extremely high pointing capabilities but it's considered a slightly more demanding sail to trim.
