Set off from the port and receive a safety briefing from the crew. Get fitted with a life jacket and harness before gently lifting off from the deck.
Float upwards with no pulling sensation at all. At your peak height, see the surrounding islands and even islands on the other side of those islands. Despite your air speed, all is quiet up there, and you can speak normally with anyone up there with you.
On the way back down, your feet will splash in the water. This is refreshing and cooling. Rise back up a bit for your gentle landing on the back of the boat. Like taking off, landing has zero impact on your body.
