We brought a new laser and within 13 months 10-15% of the hull under the water line is suffering from osmosis. The boat is raced once a week and stored on land. 70% of the time the laser is under cover. Also laser supplied boat covers that were used to protect the boat from the elements when stored outside. The Australian manufacturer is stateing "unfortunately I have witnessed how easy it is to induce osmosis into a perfectly good well made laser!" It is a worry Lasers policy, to have limited manufacturers, who can take this attitude without even a expert inspection of the hull. Is this a common problem?
