Tom Brady dominates on land, air … and now by sea — ’cause the QB just bought a multi-million dollar boat and we’ve got the pics!

TMZ Sports has learned … the Tampa Bay Bucs star ordered up a custom 40-plus-foot, state-of-the-art watercraft to enjoy during his time in Florida.

The boat was delivered on Thursday at his local marina in St. Petersburg — and Tom was as excited as a kid on Christmas!

You can see how happy he looks in the photo — smiling from ear to ear as the ship was handed over.

It’s a beautiful blue boat named “Viva a Vida” — which happens to be the name of Gisele‘s environmental conservation initiative.

The Brazilian supermodel recently announced a program to help plant over 200,000 trees in the Amazon rainforest — something she’s been very passionate about for a while.

As for the price of Tom’s boat, we’re told it usually costs around a couple million dollars — but no word on exactly how much Tom paid.

He can definitely afford it though — Tom is in the middle of a 2-year, $50 million deal with the Bucs and he’s made more than $200 million in his NFL contracts alone.

And, that’s not even including the Ugg money!
