What is the purpose of this rig?

It is not a rotating mast!

What a mess! All that because they put in a mast that was too flimsy, and on
what seems to be a cruising cat too. All that windage, and how many owners
of such boats could begin to set that lot up properly? Anyone who buys a
'boat' like that needs serious counselling IMO.
