Late last year the National Measurer determined that a particular centreboard case design that had appeared on a total of around 6 Sabres built in 2014 and 2015 was not in accordance with class rules. Owners of the boats were advised to modify their boats and this has involved a simple fix involving teh addition of some packing.Subsequent to then there were some concerns raised about our interpretaion and we elected to obtain an independent opinion. We engaged Andre Blasse to undertake this task. Andre is eminentlky qualified (International & Olympic measurer and YV technical delegate – measurement and is teh world OK president. Andre concluded that the SSAA interpretation regarding centreboard case in GRP Sabres is correct.
