This topic comes on now and then.

I just got a new boat this season. I am getting warm about storing the boat
with its mast up for the north-eastern Canadian winter. I am not all
convince yet that it a good thing to do. The radar was mounted on the mast
and the boat mast has two spreaders and in mast furling. When they
commissioned the boat, it took them 2-3 days to do so.

At this time, I do not know how long it will take me to get the mast down,
taking care of the spreaders look after the radar and prep the mast for
indoor storage in a very crowded spar shed. Maybe the wear and tear of
removing the mast, pushing it in an already overcrowded spar shed is more
than leaving the mast installed on the boat. In addition, in the spring at
launch I will have to tune the mast again and install the radar and
connections. Conversely, I have heard stories that leaving the mast on
during the winter may cause stress on the rigging and loosen the anchor
plates.

I would appreciate to get comments on this subject.
