0:00:02 > 0:00:06Eight explorers are taking on the toughest challenge of their lives,
0:00:06 > 0:00:08an extreme expedition in South America.
0:00:08 > 0:00:11That is mad!
0:00:11 > 0:00:14They're attempting a series of astonishing world firsts.
0:00:14 > 0:00:15Oh, my god!
0:00:15 > 0:00:18Going where no children have been before,
0:00:18 > 0:00:21to get to some of the most awesome places on Earth.
0:00:21 > 0:00:24We've reached the top!
0:00:24 > 0:00:26The team are following in the footsteps
0:00:26 > 0:00:28of the great Elizabethan, Sir Walter Raleigh,
0:00:28 > 0:00:31the first Englishman to explore Guyana
0:00:31 > 0:00:35as he searched for Eldorado, the Lost City of Gold.
0:00:35 > 0:00:38Led by survival expert Ben Major
0:00:38 > 0:00:40and record-breaking adventurer Polly Murray,
0:00:40 > 0:00:46the epic journey will push the eight explorers to the limit and beyond.
0:01:00 > 0:01:05Coming up. Nikita reaches dizzy new heights.
0:01:05 > 0:01:06I'm at the top!
0:01:06 > 0:01:07THEY CHEER
0:01:07 > 0:01:12But life on the ocean quickly hits a low.
0:01:12 > 0:01:14Oh, I feel so sick.
0:01:14 > 0:01:20The eight Serious Explorers arrive at London's Gatwick airport
0:01:20 > 0:01:22ready to begin their extraordinary adventure.
0:01:22 > 0:01:28- I'm not crying!- They'll be away from their families for five weeks.
0:01:28 > 0:01:30Final wave goodbye.
0:01:30 > 0:01:33The team have a ten-hour flight across the Atlantic Ocean
0:01:33 > 0:01:37to Trinidad and Tobago in the southern Caribbean, from where,
0:01:37 > 0:01:41just like Sir Walter Raleigh, they'll sail to South America.
0:01:45 > 0:01:49Oh, my god! That is awesome.
0:01:49 > 0:01:53Their ocean voyage will be on the 80-foot classic boat Scaramouche.
0:01:53 > 0:01:56The explorers will be learning to sail it themselves.
0:01:56 > 0:02:01- Welcome aboard.- This is Martin, the skipper.- Hello!
0:02:01 > 0:02:03So, this is home for the next few days. What do you think?
0:02:03 > 0:02:07I love it. It's like so old-fashioned but it's dead nice.
0:02:07 > 0:02:10It looks really cool. I'm really excited.
0:02:10 > 0:02:13I don't think we'll get seasick on here. We'll be too busy.
0:02:13 > 0:02:16Scaramouche is an old wooden schooner,
0:02:16 > 0:02:20and below deck, it's very basic with no cabins or beds.
0:02:20 > 0:02:24So this is where you're going to be sleeping.
0:02:24 > 0:02:27Yeah, on the floor. Good old roll mats, sleeping bags.
0:02:28 > 0:02:32They're still at anchor in the bay, but there's an early warning of troubles ahead.
0:02:32 > 0:02:37- I think someone's feeling sick already.- Who's feeling sick?- Me.
0:02:37 > 0:02:40- We've been downstairs for two minutes!- That doesn't bode well.
0:02:40 > 0:02:43- Are you all right?- Yeah. Can I go upstairs?- Yeah, no worries.
0:02:43 > 0:02:46On that note, I will show you a very important place.
0:02:46 > 0:02:49OK, we call it heads on a boat.
0:02:49 > 0:02:52If you can try and make it, great. Otherwise, we've got buckets.
0:02:52 > 0:02:58We don't want puke down here because everybody's sleeping bags, roll mats will get covered in it.
0:02:58 > 0:03:02We haven't even set off yet, and I already feel horrific,
0:03:02 > 0:03:06so I'll spend most of the time being sick over the side or in a bucket.
0:03:06 > 0:03:08It's worrying when you're setting off on a voyage
0:03:08 > 0:03:12and before you have the picked the anchor up, people are seasick!
0:03:12 > 0:03:16The explorers will be following in the wake of
0:03:16 > 0:03:20the great Elizabethan adventurer, Sir Walter Raleigh.
0:03:20 > 0:03:22400 years ago,
0:03:22 > 0:03:24he sailed to South America on a search for great riches.
0:03:24 > 0:03:29He had heard tales of a legendary golden city called Eldorado.
0:03:29 > 0:03:35Writing in his journal, "I have been assured by those who have seen Eldorado that for its riches,
0:03:35 > 0:03:37"it far exceeded any of the world."
0:03:37 > 0:03:40He was the first Westerner to explore
0:03:40 > 0:03:42what is now Guyana and Venezuela,
0:03:42 > 0:03:47and the young explorers will recreate key parts of his adventures.
0:03:47 > 0:03:52Beginning with a four-day ocean crossing.
0:03:53 > 0:03:55Three, two, one. Drop!
0:03:59 > 0:04:03- That's one sail. We've got another four to go.- Four!- Yeah.
0:04:03 > 0:04:05Other boats, you just push a button
0:04:05 > 0:04:10and it does everything for you, but on here, you have to do everything.
0:04:13 > 0:04:15You all right down there?
0:04:15 > 0:04:20It's time to relive the legend of Sir Walter Raleigh.
0:04:33 > 0:04:37There's a dolphin there! There's a dolphin!
0:04:39 > 0:04:44They've a journey of nearly 200 miles to reach South America.
0:04:44 > 0:04:48Today, they'll hug the coast of Tobago to anchor in King's Bay,
0:04:48 > 0:04:52before heading out into the Atlantic for a three-day crossing to Guyana.
0:04:54 > 0:04:56None of the explorers have sailed before,
0:04:56 > 0:04:58and one of the most important tasks on board
0:04:58 > 0:05:02is to steer or helm the boat.
0:05:02 > 0:05:06It's really, really nice to handle.
0:05:06 > 0:05:09It takes a few seconds to respond to what you do,
0:05:09 > 0:05:11but it's just such a nice way to travel.
0:05:11 > 0:05:15And it's also helping stop Josh feel too queasy.
0:05:15 > 0:05:18Steering, you're concentrating on something,
0:05:18 > 0:05:21so it takes your mind off being sick.
0:05:21 > 0:05:26In contrast, Michael's seasickness has gone from bad to worse.
0:05:26 > 0:05:28Not good.
0:05:28 > 0:05:31Oh, I feel so sick.
0:05:32 > 0:05:34Oh!
0:05:36 > 0:05:40- You all right, mate?- No.- No. Look at the horizon, yeah?
0:05:40 > 0:05:42Look at those rocks, the islands over there.
0:05:42 > 0:05:45If you can focus on something, that will help.
0:05:45 > 0:05:47But the advice comes too late.
0:05:47 > 0:05:50Oh!
0:05:50 > 0:05:54And unfortunately, as Michael heaves his guts up,
0:05:54 > 0:05:57it blows into the others.
0:05:57 > 0:06:01I've sick on my hand! Urgh!
0:06:02 > 0:06:04He's being sick in our faces!
0:06:04 > 0:06:06He puked over the side of the boat,
0:06:06 > 0:06:10and then cos of all the wind
0:06:10 > 0:06:14it went in my mouth and on my hands and everywhere, it was disgusting.
0:06:14 > 0:06:17I'm worried about Michael.
0:06:17 > 0:06:19When you do get a big bout of seasickness,
0:06:19 > 0:06:22there's nothing you can do. You feel absolutely useless.
0:06:22 > 0:06:26But others are enjoying the ride, with the best seat in the boat.
0:06:26 > 0:06:30It's a long way back to the driver.
0:06:30 > 0:06:33I love it. It's just pure amazing.
0:06:33 > 0:06:36It feels really cool and you can see everything underneath.
0:06:36 > 0:06:39The ship looks gorgeous from this view as well.
0:06:44 > 0:06:46- Are you all right?- I'm all right.
0:06:46 > 0:06:50By late afternoon, the team are steering into King's Bay, where they'll spend the night.
0:06:52 > 0:06:55Good man. Need you to help Megan bring down the sail.
0:06:55 > 0:06:59- It's been a hot day's work in the Caribbean sun.- Well done.
0:06:59 > 0:07:01That's brilliant. Brilliant.
0:07:01 > 0:07:04And they are rewarded with a sunset dip in the bay.
0:07:05 > 0:07:07OK, go for it, Regan.
0:07:07 > 0:07:08Go, Joshi.
0:07:14 > 0:07:16It's freezing!
0:07:16 > 0:07:18No, it's not.
0:07:18 > 0:07:21While Michael's still feeling rough,
0:07:21 > 0:07:23he joins in, hoping it will make him feel better.
0:07:28 > 0:07:31I'd do anything to cure my seasickness.
0:07:31 > 0:07:34The worst feeling in the world, being sick.
0:07:34 > 0:07:37On your own. Whoa!
0:07:37 > 0:07:41But Sammie is remaining firmly on deck.
0:07:41 > 0:07:43I'm trying to psych myself to do it but...
0:07:43 > 0:07:46Can I say, it's very important we get you in that water today.
0:07:46 > 0:07:48I need to see you swim.
0:07:48 > 0:07:52Sammie's terror of swimming became clear during auditions boot camp.
0:07:52 > 0:07:56- I'm nervous, really nervous.- OK.
0:07:56 > 0:07:59She courageously overcame her phobia in a freezing lake.
0:07:59 > 0:08:01Well done, Sammie. Brilliant.
0:08:03 > 0:08:05But now, the fear has returned.
0:08:05 > 0:08:06I will go in the water first.
0:08:06 > 0:08:10If you're not happy jumping off the boat, that's absolutely fine.
0:08:10 > 0:08:14We'll go down the ladder. OK? Come on. Let's walk down together.
0:08:14 > 0:08:16Though far from comfortable,
0:08:16 > 0:08:18she forces herself to take a dip in the bay.
0:08:18 > 0:08:19Good girl.
0:08:19 > 0:08:22Good girl. That's it. No need to swim any further.
0:08:22 > 0:08:26- It's cause there's no bottom. - You're fine. Absolutely fine.
0:08:27 > 0:08:28Please can I go back?
0:08:31 > 0:08:35'I think it is really essential that we got Sammie in the water.'
0:08:35 > 0:08:38She's not very confident and I need to know that all eight of these guys
0:08:38 > 0:08:41are good, strong swimmers.
0:08:41 > 0:08:45- You've done that now. You are fine. - I feel better that I've done it now.
0:08:45 > 0:08:48I guess I won't have to do it again, if I don't want to.
0:08:48 > 0:08:50Right, team, dinner is served.
0:08:51 > 0:08:54Michael doesn't feel up to tucking in.
0:08:54 > 0:08:58Today has been a horrific day for me.
0:08:58 > 0:09:02All I've really done is been sick.
0:09:02 > 0:09:04Hated every minute of it.
0:09:04 > 0:09:06I haven't been able to enjoy it.
0:09:06 > 0:09:07I just felt so rough.
0:09:07 > 0:09:10I'm going straight to bed. I'm tired.
0:09:10 > 0:09:12The team are looking forward to an early night.
0:09:15 > 0:09:18It's very uncomfortable and there's loads of bags everywhere.
0:09:18 > 0:09:20I've just been squashed into a corner.
0:09:20 > 0:09:24But the hold is cramped and very hot.
0:09:24 > 0:09:28We will get to sleep eventually, I think. You just get used to it.
0:09:28 > 0:09:32While the explorers have to get through just four days on Scaramouche,
0:09:32 > 0:09:35Sir Walter Raleigh's men spent around six weeks
0:09:35 > 0:09:37in even more basic conditions,
0:09:37 > 0:09:40as they crossed the entire Atlantic Ocean from Britain.
0:09:42 > 0:09:46With around 70 men, crewing the Elizabethan galleon,
0:09:46 > 0:09:48it was not unusual to lose several to disease
0:09:48 > 0:09:50or even falling overboard.
0:09:52 > 0:09:53That's it. Keep going.
0:09:53 > 0:09:58Day Two, and the team are heading into open ocean for the first time.
0:09:58 > 0:09:59Brilliant, guys.
0:09:59 > 0:10:01As they sail out of the bay,
0:10:01 > 0:10:04Polly takes them through a vital safety briefing.
0:10:04 > 0:10:06What to do if someone falls into the sea.
0:10:08 > 0:10:10Shout, point.
0:10:10 > 0:10:12"Man overboard!" And I mean shout.
0:10:12 > 0:10:18But you will be amazed how quickly a person can disappear.
0:10:18 > 0:10:19Unknown to the explorers,
0:10:19 > 0:10:23Ben decides to give a demonstration of the dangers.
0:10:27 > 0:10:31- Man overboard!- Help!
0:10:31 > 0:10:33Help!
0:10:33 > 0:10:38- Somebody keep an eye on him. - Keep an eye and point.
0:10:38 > 0:10:42As predicted, Ben is quickly disappearing into the distance.
0:10:44 > 0:10:47Someone still pointing at him? Keep an eye on him.
0:10:47 > 0:10:50Agonising seconds pass, as the boat turns back.
0:10:51 > 0:10:54Watch yourselves, watch yourselves.
0:10:55 > 0:10:59OK, good, he's got it. A couple of you, do you want to come with me?
0:10:59 > 0:11:01- Right, heave, heave.- Pull him in.
0:11:01 > 0:11:04Pull him up.
0:11:04 > 0:11:06OK Ben?
0:11:06 > 0:11:08You all right, mate?
0:11:10 > 0:11:14You can see how difficult it is to get people back in the boat.
0:11:14 > 0:11:15Nightmare.
0:11:15 > 0:11:16'It was really scary.'
0:11:16 > 0:11:20You were worried for him and then you had to keep concentrating
0:11:20 > 0:11:23so that you didn't leave him in the water too long.
0:11:23 > 0:11:26'They've got to be aware of basically the severity.
0:11:26 > 0:11:28'If someone goes over the side,
0:11:28 > 0:11:32'you can die very, very quickly in these kind of waters.'
0:11:32 > 0:11:34As they sail away from Tobago, the wind gets up
0:11:34 > 0:11:37and the sea becomes increasingly choppy.
0:11:39 > 0:11:44I've been sick again, same as normal. I just feel so rough.
0:11:46 > 0:11:48This time it's not only Michael suffering.
0:11:48 > 0:11:51The ocean waves are turning almost everyone's stomachs.
0:11:53 > 0:11:55I feel like I'm going to puke.
0:11:55 > 0:11:59Every time the boat goes up and down it makes me feel worse.
0:11:59 > 0:12:01Awful feeling.
0:12:04 > 0:12:05Oh!
0:12:07 > 0:12:09Oh, it's coming on board.
0:12:09 > 0:12:14It's horrible because you lie down, you feel fine, you get up and then you're sick.
0:12:14 > 0:12:18Lie back down, get up and you're sick, eat something, get up and you're sick.
0:12:18 > 0:12:21You can't go five minutes without someone being sick.
0:12:21 > 0:12:24Hang on, Megan, just keep your head over the side.
0:12:24 > 0:12:26Hang on to the side.
0:12:26 > 0:12:28With only Nikita left feeling OK,
0:12:28 > 0:12:32Ben shows her how to use the compass to steer the boat.
0:12:34 > 0:12:38- Look at the instruments, yeah?- Yeah. - Just sitting at about 180.
0:12:38 > 0:12:42She is just beginning to go over so bring her back a little bit.
0:12:42 > 0:12:44This is quite stiff.
0:12:44 > 0:12:49For the other seven explorers, the voyage has become sheer misery.
0:12:56 > 0:13:00Everyone, bar one, has gone down with seasickness.
0:13:00 > 0:13:05The boat just stinks of vomit. What can I say? We haven't got a crew.
0:13:05 > 0:13:10Sometimes it does get quite lonely and a bit boring.
0:13:10 > 0:13:12They are seasick. It's not their fault.
0:13:12 > 0:13:14No one but Nikita has eaten all day
0:13:14 > 0:13:18and by late afternoon, some of them try to brave a sandwich.
0:13:19 > 0:13:23I'm not really feeling much better at the minute.
0:13:23 > 0:13:25But maybe the sandwich will help.
0:13:32 > 0:13:33It's terrible, isn't it?
0:13:33 > 0:13:37I guess the cheese sandwich didn't go down that well.
0:13:43 > 0:13:46My whole career plan for when I leave school,
0:13:46 > 0:13:51going in the Navy, in the Marines, I don't want to do that any more.
0:13:51 > 0:13:55I've been here for two days and just through hating this boat,
0:13:55 > 0:13:57it's already changed my life.
0:13:58 > 0:14:01- Josh, can you chuck me that bucket, please?- Yeah.
0:14:01 > 0:14:03Down below, they face a grim night ahead.
0:14:06 > 0:14:10Josh was sick in the toilet
0:14:10 > 0:14:12and it seems to have overflowed.
0:14:12 > 0:14:14You get really, really dizzy.
0:14:14 > 0:14:18You get a really sore head very quickly down here.
0:14:18 > 0:14:20So, um, not feeling great.
0:14:23 > 0:14:25Fortunately, by early next morning,
0:14:25 > 0:14:29the weather has changed completely and the sea is much calmer.
0:14:32 > 0:14:33Morning, morning.
0:14:35 > 0:14:39Have we got anybody alive down here? Michael, you with us?
0:14:39 > 0:14:43So, are we feeling a little bit better this morning?
0:14:43 > 0:14:45Yeah? Come on, guys.
0:14:45 > 0:14:49Did you actually sleep like that with your sunglasses round your neck
0:14:49 > 0:14:52and your head torch on your head?
0:14:52 > 0:14:55At the minute, I'm feeling pretty good,
0:14:55 > 0:14:58but knowing my luck, I'll be sick again.
0:14:58 > 0:15:01Most have at last got their sea legs.
0:15:01 > 0:15:03Who wants strawberry jam?
0:15:03 > 0:15:08Their reward for feeling better is to get the boat ship-shape,
0:15:08 > 0:15:11removing all traces of yesterday's seasickness.
0:15:14 > 0:15:16OK, scrub, scrub, scrub.
0:15:18 > 0:15:21It's an interesting technique, this sitting technique.
0:15:21 > 0:15:24I'm not sure how effective it is.
0:15:24 > 0:15:27They're even up for a bit of fishing.
0:15:28 > 0:15:30ALL: Oh!
0:15:30 > 0:15:33Well caught, but I'm afraid we have to chuck this one back in.
0:15:33 > 0:15:35Not for eating.
0:15:35 > 0:15:38- Wee!- There we go.
0:15:40 > 0:15:43This is my favourite day because everyone else is not sick.
0:15:43 > 0:15:46- We're all happy. - Yeah, everyone's happy and talking.
0:15:46 > 0:15:49This is the first day in the trip that I haven't been sick, yet.
0:15:49 > 0:15:52You came up, "Bleurgh," get up, "Bleurgh."
0:15:52 > 0:15:55I was asleep, I heard you go, "Are you all right, Josh?"
0:15:55 > 0:15:57You went, "Yeah, bleurgh!"
0:15:57 > 0:16:00He just, "Pfff", all over my face. Ugh!
0:16:00 > 0:16:05Despite the high spirits, most can't wait to get off the boat.
0:16:05 > 0:16:09Really crave some land, some solid, flat land.
0:16:09 > 0:16:12I just want to get there, you know what I mean?
0:16:12 > 0:16:15Never thought I'd hate the sea as much as I do.
0:16:15 > 0:16:18The explorers are past the halfway point
0:16:18 > 0:16:20in their 200-mile crossing to Guyana,
0:16:20 > 0:16:24and from here, they'll be doing all the navigating for themselves.
0:16:26 > 0:16:30In Elizabethan times, navigation was very hit and miss.
0:16:30 > 0:16:32Using basic instruments like astrolabes,
0:16:32 > 0:16:36they would take readings from the sun, and then try to plot
0:16:36 > 0:16:39the boat's route on charts, which were often very inaccurate.
0:16:44 > 0:16:490, 9 degrees, 14.264.
0:16:49 > 0:16:52Unlike Raleigh, the Serious Explorers have
0:16:52 > 0:16:54an on-board GPS to help them navigate.
0:16:54 > 0:16:55That's where we are now.
0:16:55 > 0:16:59And they've got an accurate map to plot their position
0:16:59 > 0:17:00as they sail towards South America.
0:17:00 > 0:17:02Can you tell me off the map,
0:17:02 > 0:17:07how far we reckon it is to where our destination is?
0:17:07 > 0:17:08That far.
0:17:08 > 0:17:09LAUGHTER
0:17:09 > 0:17:11They've got to reach Guyana by tomorrow
0:17:11 > 0:17:15for the expedition to stay on schedule, but there's a major snag -
0:17:15 > 0:17:18the wind has almost completely dropped.
0:17:18 > 0:17:21Problem is, we've now come to a standstill.
0:17:21 > 0:17:25That's why you can hear all this slopping going on with sails overhead.
0:17:25 > 0:17:29We are literally floating around, no wind, going nowhere.
0:17:29 > 0:17:32At the moment, there's absolutely no way we're going to make it.
0:17:32 > 0:17:36While they wait for the wind to get up again,
0:17:36 > 0:17:39there's a chance to learn another vital skill -
0:17:39 > 0:17:42climbing the rigging easing rope ladders, known as ratlines.
0:17:43 > 0:17:47I want to get you guys to go up the ratlines.
0:17:47 > 0:17:48ALL: Oh!
0:17:48 > 0:17:53The reason being is to actually use them as a method of looking out.
0:17:54 > 0:17:58Raleigh's men had the precarious job of shinning up and down the ratlines
0:17:58 > 0:18:00in all weather conditions.
0:18:00 > 0:18:03High above the deck, they'd adjust the sails
0:18:03 > 0:18:08and also take shifts in the crow's nest, so they could keep a lookout.
0:18:08 > 0:18:11Land discovered!
0:18:13 > 0:18:15Nikita volunteers to go first.
0:18:15 > 0:18:17She'll be clipped on at all times for safety.
0:18:17 > 0:18:23Just come round, because you're safe now. Up, that's fantastic.
0:18:23 > 0:18:27You can imagine in the olden days, they actually didn't have harnesses,
0:18:27 > 0:18:30they would just go up in the wildest of seas.
0:18:30 > 0:18:33The higher she goes, the more it sways.
0:18:37 > 0:18:41Oh, it's scaring me, just watching her do it. Oh, she's so high up.
0:18:41 > 0:18:43If she falls, that's going to hurt.
0:18:45 > 0:18:48Nikita presses on, heading ever higher.
0:18:49 > 0:18:51Wow!
0:18:51 > 0:18:55She doesn't get seasick, she's not scared of heights, can you find a more annoying person?
0:18:55 > 0:18:57Almost!
0:18:57 > 0:18:59I'm at the top!
0:18:59 > 0:19:03- Well done! - That set the benchmark quite high.
0:19:04 > 0:19:08Michael may have only just got over his seasickness,
0:19:08 > 0:19:10but he's very competitive.
0:19:10 > 0:19:15I just hope that it's not too swingy up there, in case I get sick.
0:19:17 > 0:19:19- It's really swaying now.- Whoa!
0:19:19 > 0:19:22He's determined to make it all the way up.
0:19:25 > 0:19:28Whoa! That was close.
0:19:28 > 0:19:29Well done.
0:19:29 > 0:19:33You're pretty good, but you swing around everywhere.
0:19:33 > 0:19:37- This time, it's others who feel the effects more than Michael.- Oh!
0:19:39 > 0:19:42- Right, you've done one rung. - I know, and I feel sick already.
0:19:42 > 0:19:44Please can I come down?
0:19:44 > 0:19:47- Feeling all right?- No.
0:19:47 > 0:19:49- No?- I feel sick.
0:19:49 > 0:19:53I'm not good with heights normally, let alone at sea.
0:19:53 > 0:19:57And once again, Regan finds himself heaving over the side.
0:19:59 > 0:20:00Not good.
0:20:00 > 0:20:02I'm proud of how far I got.
0:20:02 > 0:20:06Not quite sure how far it was, but I'm proud that I did something.
0:20:06 > 0:20:09The boat is still dead in the water, and the leaders decide
0:20:09 > 0:20:13it's an ideal chance to get a first proper wash in days.
0:20:13 > 0:20:19Straight in, you get salty, out, fresh water rinse, not a problem.
0:20:24 > 0:20:26But in the open ocean, miles away from land,
0:20:26 > 0:20:28it's Sammie's idea of a nightmare.
0:20:31 > 0:20:33Woo!
0:20:33 > 0:20:36I'd rather smell. I'm not going in.
0:20:36 > 0:20:39Hold your nose. Whoa, brilliant.
0:20:39 > 0:20:43- Why don't you come in for a jump with Nikita, Megan and myself?- No!
0:20:43 > 0:20:46Yesterday, it was a bigger swim away from the ladder.
0:20:46 > 0:20:50- Literally, you get in... - Sorry. I wish I could, but... No.
0:20:51 > 0:20:54OK, fair enough, and I respect that.
0:20:54 > 0:20:58But, there are other moments in this expedition
0:20:58 > 0:21:02that I'm going to be looking to you to be confident in the water,
0:21:02 > 0:21:04and I haven't seen that confidence yet.
0:21:04 > 0:21:06I know you don't like it and I know you don't want to,
0:21:06 > 0:21:08but I know that you can do it.
0:21:08 > 0:21:11Please don't make me, I really can't.
0:21:14 > 0:21:17Sammie, I don't want to make you unhappy about it.
0:21:17 > 0:21:20All I know is that Polly and myself will be with you
0:21:20 > 0:21:22every step of the way.
0:21:22 > 0:21:25OK, I'm not going to push you any more.
0:21:25 > 0:21:28Just think about it for five minutes, OK?
0:21:29 > 0:21:32Don't use too much, everyone's got to use that.
0:21:32 > 0:21:34Oh, oh, oh!
0:21:38 > 0:21:42After much thought, Sammie takes the brave decision
0:21:42 > 0:21:45that she's going to try to get over her fear, once and for all.
0:21:49 > 0:21:52Getting into the water in the middle of the ocean
0:21:52 > 0:21:54is a terrifying challenge for her.
0:21:57 > 0:21:59Well done, Sammie, brilliant. OK, that's it.
0:21:59 > 0:22:02Just get used to the water.
0:22:02 > 0:22:04She's really scared of the water.
0:22:04 > 0:22:05She won't let go.
0:22:10 > 0:22:13And although she stays by the boat in the ocean swell,
0:22:13 > 0:22:15she proves herself to the leaders.
0:22:15 > 0:22:18- You've done well. Sammie? - I need to come out.
0:22:18 > 0:22:20That's all we're going to do.
0:22:20 > 0:22:22well done, just come on up.
0:22:22 > 0:22:25Well done, Sammie.
0:22:25 > 0:22:29You done it, you said you wouldn't, but you got in, you did it.
0:22:29 > 0:22:32When I think back at it, I'm really glad I did it,
0:22:32 > 0:22:35because I know I would have been beating myself up, saying,
0:22:35 > 0:22:38"I should have done it." I'm really glad I did it now.
0:22:38 > 0:22:42The wind is at last getting up, but it's going to be
0:22:42 > 0:22:46a close run thing to get in on schedule tomorrow.
0:22:46 > 0:22:49So the team will have to sail on right through the night,
0:22:49 > 0:22:51and they're heading into busy shipping lanes.
0:22:53 > 0:22:58They've got to concentrate driving, watching out for these big, big ships.
0:22:58 > 0:22:59Really, really scary.
0:22:59 > 0:23:02What we're asking them do is two hours on,
0:23:02 > 0:23:05six hours off in a rotation system.
0:23:05 > 0:23:08We've just got to be on it.
0:23:08 > 0:23:10I'm not looking forward to the late night shift
0:23:10 > 0:23:13because I've got a horrible one, bang in the middle of the might.
0:23:13 > 0:23:16I've got to do one more two in the morning,
0:23:16 > 0:23:18which - that should be a bit of a bummer.
0:23:20 > 0:23:22To stop them falling over board in the dark,
0:23:22 > 0:23:26they have to put on harnesses and clip on to ropes.
0:23:27 > 0:23:30The two explorers on duty will always have an adult with them
0:23:30 > 0:23:34for safety but there's still a lot of pressure.
0:23:35 > 0:23:40You have to concentrate and there's no time to be tired,
0:23:40 > 0:23:41so like you're kind of really alert
0:23:41 > 0:23:46because you're in charge of the boat, which is carrying, like, 20 people.
0:23:46 > 0:23:48So you have that responsibility.
0:23:48 > 0:23:52While one explorer steers, the other keeps a look out.
0:23:52 > 0:23:58There's a boat over there, it's quite a distance away though.
0:23:58 > 0:24:03Meanwhile, the others desperately try to grab a few hours sleep between shifts.
0:24:09 > 0:24:10Steering in the dark,
0:24:10 > 0:24:14Michael uses the stars just as Raleigh would have done.
0:24:14 > 0:24:18I'm following the star which is right ahead of me,
0:24:18 > 0:24:21and if I keep dead in line with that,
0:24:21 > 0:24:25instead of looking at the compass, I can use that and it's a lot easier.
0:24:27 > 0:24:30The night seems never ending,
0:24:30 > 0:24:33and it gets harder and harder to stay awake.
0:24:34 > 0:24:35Shattered.
0:24:36 > 0:24:38I just want to go to sleep.
0:24:38 > 0:24:43Can't wait to get this shift over and in my bed.
0:24:43 > 0:24:49In their exhaustion Chanel and Sammie are having trouble charting their progress on the map.
0:24:49 > 0:24:52This is where we were at 7.30.
0:24:52 > 0:24:56Quarter to ten, if we did go via the way we've done it,
0:24:56 > 0:25:00then we'd literally be on land already.
0:25:00 > 0:25:03It's a magical board that can fly above land!
0:25:03 > 0:25:06I've definitely done it wrong.
0:25:09 > 0:25:14It's 5.00am and Megan and Regan prepare to take the very last watch.
0:25:16 > 0:25:21It soon becomes clear the explorers' marathon night sail has paid off.
0:25:21 > 0:25:25We're only 15 miles away to getting on land.
0:25:25 > 0:25:29When the sun rises over there, we get to see Guyana.
0:25:29 > 0:25:31They've broken the back of the journey
0:25:31 > 0:25:36and they're rewarded with the most stunning dawn of the entire trip.
0:25:38 > 0:25:39Wow!
0:25:39 > 0:25:40That's so pretty.
0:25:40 > 0:25:43I think it looks gorgeous.
0:25:44 > 0:25:48We're about ten miles to reach land so we haven't got far.
0:25:51 > 0:25:54And at last, after four heavy days of sailing,
0:25:54 > 0:25:56the sight they've all been waiting for.
0:25:56 > 0:26:01Can you see the sandy beach? This is our final destination.
0:26:01 > 0:26:05This is where we're going to be making land fall on South America.
0:26:05 > 0:26:11I can't wait to get my feet on to that dry land for the first time in four days.
0:26:11 > 0:26:13I have never been so happy in my life.
0:26:15 > 0:26:18It's been a challenging start to their five-week adventure,
0:26:18 > 0:26:20following in the wake of Sir Walter Raleigh.
0:26:20 > 0:26:25To start off with, I really disliked the boat, because I felt so ill,
0:26:25 > 0:26:32but as the journey's gone on, I've started to enjoy being on the sea, like a real explorer.
0:26:32 > 0:26:33It's quite an experience actually,
0:26:33 > 0:26:38to like know this is how Raleigh came on a little boat like this
0:26:38 > 0:26:42and just sailed there, not knowing where he was going.
0:26:42 > 0:26:46Getting ashore after so long aboard has an unexpected effect.
0:26:46 > 0:26:47Welcome to South America.
0:26:47 > 0:26:49Oh, I feel like land sick!
0:26:49 > 0:26:50Land sick!
0:26:50 > 0:26:54I feel really wobbly from coming off the boat. Sitting there, going like that.
0:26:54 > 0:26:56You when you've just got off a roundabout.
0:26:56 > 0:26:59And you go like that and everything's still moving.
0:26:59 > 0:27:03You will be rocking for days.
0:27:04 > 0:27:09The area's uninhabited and they'll be staying overnight in a basic shelter on the beach.
0:27:09 > 0:27:11This is what Raleigh would have experienced.
0:27:11 > 0:27:15He would have knocked up something not dissimilar to that
0:27:15 > 0:27:19but the first stage was hitting the South American coast,
0:27:19 > 0:27:22and that's what we've just done.
0:27:22 > 0:27:25I've wanted to come here nearly all my life. It's amazing.
0:27:25 > 0:27:29So beautiful. A postcard picture, that's what it's like.
0:27:29 > 0:27:32It's so mind blowingly cool.
0:27:33 > 0:27:39What they don't know is that their epic expedition is about to get far tougher.
0:27:39 > 0:27:41It's time to toast their achievements so far.
0:27:41 > 0:27:47Thank you to Scaramouche for safely delivering us to the coast South America.
0:27:47 > 0:27:48- To Guyana!- To Guyana.
0:27:48 > 0:27:50Cheers!
0:27:52 > 0:27:56Next time on Serious Explorers, a massive mountain to climb.
0:27:56 > 0:27:59It's all bad.
0:27:59 > 0:28:00Black bags.
0:28:00 > 0:28:03Learning to go - the green way.
0:28:03 > 0:28:04I can't go.
0:28:04 > 0:28:06And a nightmare for Chanel.
0:28:06 > 0:28:09I'm like the elephant man at the moment.
