What type of roller furling
do you have?
I specifically set up my C25 to be able to lower/raise the mast
. Of course the a-frame is an important part of it, as well as the tangs that the lower forward shrouds connect to. However, one of the other considerations is the roller furling
. I chose the CDI furler
because it has a plastic extrusion that can be abused and bent. It also has an internal halyard
which allows the boat's original jib halyard
to be used as the stopper/brake. Furlers that have an aluminum
extrusion will require more care and probably a few helpers.
As far as the length of the a-frame arms, they do not need to reach all the way to the bow. For me, because of the bridge clearance, the a-frame was about 18" -2' short of the bow.
