I have a yatch and I live on it 6 months a year. Can I deduct any intrest payments.

I've been paying on it since 9/17/2015

Yes, if your yacht has a galley, a head and a sleeping berth, it can be considered a home or a second home, and you can deduct the interest payments on a  loan secured by the vessel as home mortgage interest.
