I have purchased 5 new lasers over the last 2 years (family racing) and 4 of the 5 have the centerboard trunks fracturing from the boats. This is manifested by stress cracking seen on the bottom of the boat surrounding the trunk. Two of the boats have also shown bulging through the hull where the mast step contacts the hull. Two of the boats have been raced in only two regattas (Orange Bowl & MWE 2013) and have had only two days of practice each. Our racing boat composite specialist says this is not repairable and Laser Performance is balking at replacement! All 4 of the boats that are having issues were manufactured in the USA. The one without an issue was manaufactured in the UK. Has anyone else had these problems in this series of boats and has anyone else had any remedies?
