Kate Hudson -- Awesome Boat Party ... Cheese Puffs & White Wine Included (PHOTO)

Kate Hudson is NOT some snooty Hollywood actress -- which is awesome -- and proved it with a bag of cheese puffs and a bottle o' wine (twist off, naturally) ... ON A BOAT.

This ain't the yacht life either -- Kate's version of #SundayFunday was chillin' on a lake somewhere in her bikini on a pontoon boat.

By the way, white wine was served in plastic cups, and her hashtags on the pic included: #FootballLiveFeed.

Kate Hudson. Officially on the "cool chick" list.
