water based bottom paint

If the snow ever melts here in the northeast, I can finally get started on getting the boat ready. I've been using Interlux ACT as bottom paint for years and am wondering if I shouldn't switch to a water based paint - it's much easier to apply and I'm tired of applying bottom paint every season. What are people's experiences with water based paints here in the northeast? I was thinking of Pettit Hydrocoat. It's got to work - if there is one thing that's worse than applying bottom paint, it's scraping off barnacles at the end of the season .
