Measuring a mast for MR922

21/04/2015 17:53:39

I am trying to find out how to measure the mast on 922 (built in 1959). Do I follow the rules now or those at the time? And if it is those at the time, where do I get a set of the class rules from 1959 from (and no I don't have e measurement certificate for her)

Many thanks
