Boat
 
So we want to keep a flat bottom boat in the water all year round. Anybody know what kind of paint is the best for this?

What's made of?
Salt or fresh water?
Got a bilge pump in it, or a full cover?

Ayuh,.... With the lack of Info, I'll suggest Rustoleum enamel...

Antifouling bottomside paint below the waterline, topside marine paint above. Interlux products are a good choice and relatively easy to find.

Raced and restored sailboats once. My fave was a Choy Lee Lion 35' footer that was beyond pretty. She had a fiberglass coating on the hull be we still had to pull her out of the water or dive underneath her to get little creatures off that slowed us down.

Joe is dead on asking where this boat of yours is to float. Flat bottomed, I guess she moves under power and not with sails? She would not hold up well without a keel in any currents. I raced catamarans once. So much fun. It was like drag racing. Things had no keels though so when tides and waves hit you. You prayed.

How long and tall is she? Not that it matters or is at all relevant to your question. You are going to have to lift her from the water though and I know what that costs.

If you are going to leave her in the water all year. I would seriously think about not painting her hull but laying down resin and fiberglass cloth, matting or even something like Kevlar if you think you might run her over rocks or something.

On the other hand, I used to be the designated sail repair fetcher. I would sail the Lion from Bezerkeley to Sausalito to pick up sails. I often wondered what was painted on the bottom of the houseboats in Sausalito. Will the people onboard survive when, hopefully even today, all of California snaps off and falls into the Ocean? If Florida were to fall in the Atlantic too? I would be so happy and a truly proud American again.

With those land masses missing, I would support annexing Vancouver and Toronto as something like a Puerto Rican situation. I might even endorse the concept of fuel guzzling power boats.

Marine paint only

If it's aluminum you would never use a copper based bottom paint. It will cause pitting.
There's a whole process you have to go through for applying bottom paint to an aluminum hull.
If you go on the Interlux or Pettit web sites there's instrutions on how to do it.

Second on Petit, if fiberglas and salt water use Trinidad SR, get 2 yrs out of coating.
