A few months back there was a thread re a ML 42 - there were issues with the rudder design that made steering while sailing deep downwind difficult. Some 42s had been modified to address this issue, others had not. Try to contact Sailnetter Eskfreedom for more info.
It's worth checking whether or not the larger models had the same issues, and/or whether the manufacturer addressed them. Unfortunately Cooper is no longer producing boats so that info may be difficult to come by. Stan Huntingford, the designer, has passed on so that avenue may be closed too.
Check Pacific Yachting magazine back issues for reviews/drawings for research - there may be something on their website....
