It depends! It may be a brigantine
The main is the largest mast
whether it is in front of or behind the other mast(s). In a two-master. if it is the forward mast
, the aft mast is a mizzen and you have a ketch or yawl. If it is the aft mast, the front mast is the foremast and it may be a schooner or a brigantine depending on the sail. (A brigantine has square sails
on the foremast)
It gets more complex with more than two masts
