Yesteray I rig my sail again, I had 25 cm extension in the DH and the sail finally rig nice, deep under the bishbone and the wrinkles touching the marks in the leech... Then I go to put my harness...... The mast blows and the sail explode in the sewing of the front of the mast I think there is no option to re sew without damaging more the sail..... I am on deep depresion. Is the 3rd Gaastra mast in a year..... but I think my sail will never be the same anymore...... I think I will left the sport..
