My concerns over several potential problems inherent with the in-mast
furling system led me to research the in-boom furling system.  When I bought
#1070 new in October 2005 I had Catalina change out the in-mast furling
system /mast to an in-boom furling system.  Boat was commissioned and
sailing by mid-Jan '06.  Works like a charm, and you have a full roach with
normal battens.  If the in-boom furler were ever to jam (has never occurred)
you can always just lower the main.  I've never understood why more owners
do not opt for the in-boom system.
