What you could also try to borrow is a Jin Pole
: basically a short pole that is raise the mast.
If your Mast is deck stepped the method is to pivot the mast at the step: the Antrim 27
and Chrystler 22
show two different methods.
If your Mast is stepped on the Cabin Sole then the mast is raised vertically above the Partners and slowly lowered into position. Here is some discussion on Jin Pole design for a J24
If you have any friends that race a Mumm 30, J24, J80, Melges 24, 32 etc. they may have a Jin Pole that they routinely use at regattas. Usually for a few Beers they will be happy to help out.
