Mizzen mast wiggle?

[Atavist]

Just started out on a run for the chesapeake from New Bedford, MA... all was well, going along nicely on a beam reach with a beam sea... a bit rolly but nothing to worry about... that is until I realized that with each roll the mizzen mast was rotating about 5 degrees each way... watching this for a while I finally looked up and realized that the reason is the weight of the wind genny and radar which as the boat rolls side to side turns the mast a bit one way then the other.... is this something to worry about... This is the mizzen on my pearson 365 ketch .... it's deck stepped but I've actually never had the mast off so I'm not sure how securly it is seated.... is it safe for my mizzen to have this slight rotation? 

we're postponing and about to put in at a port of refuge due to this... I'll talk to the previous owner in the morning and hopefully get some more info on the stepping arangement....

all input greatly appreciate... with any luck this is not something to worry about and we just get a good nights sleep and then take off again tomorrow.

For those who might be curious my question has been answered.  the mizzen on the 365 ketch is a socket which fits over a post that is part of the mast step... as such there is no danger of it jumping or twisting off as long as the stays hold, I tightened my stays down right hard (harder than I normally would) keeping them well balanced and this has fixd the mast twist problem.

Also, because there is no fore and aft support with the exception of the triasic stay, (stay between the main and mizzen) do not be alarmed that the mizzen will pump fore and aft.  This motion becomes more apparent when plowing through short chop.  This is normal and not a problem.
Good sailing... Dale Tanski
