Look at the MSOG site at the flushdeck M17 Amy. It whows a masthead extension
to place the top of the pabkstay further aft to clear his full batten main. I
have had a similar masthead extension fabricated for Griselda which also has a
full batten main but she is not yet refurbished an in the water to test it.
