now, can anyone spot alasdair? there he is.ut all of that is about to be disturbed because it's race day. music: funiculi, funicula by luigi denza and who better and who better to explain to us how this competition works than some of the drivers themselves? e1 is a brand—new racing concept. it's foiling boats with an electric motor in a format that's never been done before. the course here is basically a big figure of eight, but it's a little bit more complicated with the long lap and the starts and things like that. so, you'll see a series - of single—point turns and then turns that have larger apexes. we're racing in some really spectacular locations on the sea and lakes and we're really trying to push the foiling technology to the max. so, every team has a male and a female pilot, and it's up to the team to decide which pilot will go first. after the first race, they'll alternate from there. qualifying's done in a single—boat format, so we're all about maximising our one lap time, and then we go into the semifinals and the f

now, can anyone spot alasdair? there he is.ead racing. this stage has been set. five teams are in the final, but who will win? there's only one way to find out. definitely in e1, the most - challenging part is the starts. getting those right can really affect the race. i you want to get in the clean water at the front because, as soon as you're behind, you're in the wake of the other boats. and those waves can really interrupt how the foil performs. you can always tell when you're having a really good lap because the race has this kind of hum to it, when you're really cooking and flying and it's really unlike anything — it's unlike any boat, any jet ski, any watercraft. the course is a very simple loop, but those green buoys mark an extra special part of the track, and the teams have to choose very wisely when to take that turn. you have to take the long lap one lap during the race. you can win or lose races with long laps. if you're at the back, you can do it early and then try to catch the gap back when you've got some cleane
