Beyond Oak Island

More Spanish ships sunk than got to Spain.

I think there's three million wrecks

and less than one percent of them have been found.

- Absolutely. - Any galleon is worth

- a billion by itself. - Wow.

The fleet hadn't gone back in two years, so it was loaded

with treasure.

Jewels on board have to be mind-boggling.

Ooh! It's 22.5-carat Inca gold.

This would've been destined for queen Isabella.

This would be

the oldest shipwreck

in the Americas.

- Baby! - You found the san Miguel.

Absolutely we believe we found it.

All the while we were growing up,

my brother and I were fascinated

with finding treasure.

Pirate treasure,

cursed treasure.

Civil war gold.

Now that we are grown up

and engaged in our own treasure hunt on oak island...

We've never lost our interest in solving mysteries.

- Whoa. - -Or in finding treasures.

So now we enjoy reaching out to other treasure hunters.

- We want to hear the stories... - X marks the spot right here.

- There. - -...And find out more.

- And who knows... - I got it.

Maybe we can help them with their search.

Not only in America.

Wow. That is gold.

- But all over the world. - Yeah!

Beyond oak island.

Right now, as we sit here,

despite all the difficulties you guys have faced,

I think this season, in a lot of ways,

thus far, has been one of your most productive ever.

We're making a lot of progress.

I think it's more surprising

than productive.

It is productive but, I mean,

we went looking for specific things

in the money pit, in the swamp,

at the ball foundation.

We didn't find the things we were looking for...

- We found other things. - But we found

more remarkable things than what we were looking for.

Moving forward, I mean, I'm trying

to think of things that have been left on the table.

I mean, you've already hit so many targets this season.

I'm trying to f-figure out anything

that maybe has been left behind a little bit.

You know, like, c-1, here.

Any chance that we might send a diver down there at any point?

Is it possible yet this year? I suppose it is.

- Anything's possible. - Yeah, anything's possible.

- Well... - Any dives anywhere?

There may be a dive coming up, all right.

It could be a recovery dive.

- Ooh. I like to hear that. - There you go, yeah.

- That's the dream. - Yeah, and if... yeah...

And if-if that came to pass,

- we'd need john Chatterton. - I love it.

I would want Chatterton.

- He's the man. - He's proven. - He's unparalleled.

John Chatterton is among the most accomplished

deep-sea divers in the world.

Over the course of his career, he has explored

such legendary wrecks as the rms Lusitania,

the Andrea doria

and even the titanic.

And just like rick and Marty lagina,

john's passion for treasure hunting

began when he was just a boy.

As a kid, I grew up at the beach.

So, I was surfing, fishing, crabbing, swimming.

I was in the water all the time.

When I was ten years old,

I had my first scuba dive.

And I'm looking down and I'm just watching

the rays of light going down into the bottom.

And it made an impression on me.

"What's on the bottom?"

And quite literally, I had an epiphany.

I had a dream.

I had found what I'm supposed to do.

And I'm still doing it.

I always enjoy talking to john Chatterton.

I guess we have a few reasons. L-let's get him on the phone.

You got his number?

Not many people have done what he's done...

- No. - In the water.

- Always interesting. - Yeah.

Let's talk to the great john Chatterton.

- I love it. - All right.

There he is.

- Hello, john. - Hey, john.

Hey, guys, how are you?

We're still living the dream, you know?

Who gets to do this, right?

Absolutely, I totally understand that one.

Hey, listen, thanks for your time.

We're calling, really, for two reasons.

And this is good news, john.

There may be a couple more dives,

sort of technical dives, that we need to do

in and around the money pit,

and I want to make sure you're still interested.

Whatever I'm doing, I'll make room for you guys, absolutely.

- That would be great. - -I-I love oak island,

and, I-I love what you guys

- are doing up there. - Well, we are

similarly impressed with what you did for us here.

I still shiver a little bit,

when I think about that 10-x dive.

- You ready? - Ready.

Going down.

Okay. Stand by.

Stop! Stop! Stop! Stop! Stop!

That's my idea of, like, a-a fun afternoon.

I know, that's the part

I find amazing, okay?

That was impressive, though. It really was.

You know, pray for peace, prepare for war.

So long as you're prepared with

a contingency plan that works,

- that's just part of the job. - Well, listen,

we're-we're, gratified to know you're still interested.

Hey, you know what? Anything you guys are doing, I'm in.

All right, good deal, john.

Appreciate that. Here's the other reason.

What have you been up to?

We just got back from some dives off the coast of Florida.

We're very much interested in a wreck called

the florandina, which was part of a-a larger treasure fleet.

And we believe, if we can pull this together,

this could be an important find for us.

One month ago...

- Hi, guys. - How you doing? - Welcome aboard, fellas.

Just off the coast of key largo, Florida,

john Chatterton and his team conducted a dive operation

in search of the florandina,

a Spanish galleon that sank in 1733

carrying a fortune in gold, silver and jewels.

Okay. That should do it.

Each member of the team possesses a specific skill set.

Lead researcher john mattera is a former security consultant

who first began hunting sunken galleons in his 40s.

It was the realization of a childhood fantasy.

I grew up on Staten island in new york,

in... about two blocks away from the harbor.

We had a bunch of old shipwrecks,

pretty much in front of my house.

Old wooden ships from the 1800s and...

So I've been pretty much obsessed with shipwrecks

since I was a young kid.

So I always said that when I was older and I'd get rich,

that's what I wanted to be.

I never got rich, but this is kind of what I do now.

I'm a researcher and, I find shipwrecks.

What do you think? 50 feet?

Okay.

The third member of chatterton's team

is Howard Ehrenberg.

His dual talents as both a seasoned scuba diver

and computer expert

allow him to play a unique and valuable role.

I'm the techno geek of this community that we have here.

What side do you think you want to tow off of?

- We'll tow off the starboard side. - All right.

I like doing tech stuff and analyzing

the data and making everything work.

All right, captain, we're clear.

All right, here we go.

The wreckage of the florandina is believed to lie

just a mile off the Florida coast.

It is one of only two ships from the famously rich

1733 Spanish treasure fleet that has yet to be found.

The final journey of the florandina began

on Friday the 13th of July, 1733.

That morning, as part of a heavily-armed fleet

of 21 Spanish ships

that had come to the region in 1731,

it departed Havana, Cuba, to travel home to Spain

with one-third of a vast cargo of goods,

silver, gold and jewels

that king Philip v needed to save his failing economy.

The fleet hadn't gone back in two years,

so it was loaded, loaded with treasure.

And as they were coming back,

they would come north along the straits of Florida

and they would make a right-hand turn around Bermuda

and then it would go to the Azores and then to Spain.

Just off the Florida keys,

the wind shifted abruptly from the east

and increased in velocity.

The ships were caught in a hurricane.

The Spanish commander, Rodrigo de Torres,

tried to turn the fleet back, but his efforts were in vain.
