Zo, dat was even aan de bak vanmiddag. Toen we met zn allen aan de kant stonden leek het nog niet zo te waaien. Eenmaal op het water flinke vlagen en de windrichting niet optimaal en daardoor over de chop.
Op de kant toen ik stopte kwam ik er helaas achter dat mijn vin iets heeft geraakt. Deze is een stuk korter geworden. Totaal niets van vernomen, en weet dus ook niet wanneer dit is gebeurd.
