Don’t you hate when you’re out on your private yacht, going for a swim, when those pesky sea creatures start bothering you? Me too! Well, good thing there’s Euroship’s ‘Magic Swim.’ It attaches to your private boat and floats behind it, since its constructed of PVC material that weights between 25 and 30 kg. Sea water enters the Magic Swim through filtered gates that keep out things like jellyfish and giant squid. So you can toss the old beach ball around in safe waters.
