A New Way to Explore the Reef

If you have browsed Oahu ocean tours, you may have seen the words “Sea Bob” and “submarine scooter” and wondered what on earth they are. These are two of the most fun, futuristic ways to explore Maunalua Bay, and most visitors have never heard of either. Here is a simple guide to what they are and who they are for.

What Is a Sea Bob?

A Sea Bob is a powerful handheld underwater scooter. You hold on, point where you want to go, and the motor pulls you through the water while you glide along the surface or just below it. It takes almost no effort, so you can cover more of the reef and feel a little like a dolphin yourself. It is a thrill for anyone who loves a bit of speed and adventure in the water.

What Is a Submarine Scooter?

A submarine scooter is completely different, and wonderfully easy. You sit on a scooter with a clear air-filled dome over your head, and it carries you along the sandy sea floor while you breathe normally, no swimming or scuba skills needed. Your hair does not even get wet. It is perfect for people who want to see the underwater world up close without snorkeling or diving.

Which One Is Right for You?

The two suit very different moods, so pick the experience that fits you.

  • Choose a Sea Bob if you want an active, exciting glide across the reef.
  • Choose a submarine scooter if you want a calm, easy, hands-free look at the sea floor.
  • Both are guided, use safe equipment, and work for beginners.

Where You Do It

These adventures take place in Maunalua Bay on Oahu’s south shore, a calm, protected stretch of water with reefs and marine life. Because it is guided and gentle, it is a great option for families and first-timers who want something different from a standard boat tour. As always, treat the reef and any sea life you meet with care and give turtles their space.

Try Something Unforgettable

Sea Bobs and submarine scooters turn a day on the water into something you will be talking about long after your trip. Whether you want the rush of a powered glide or the ease of cruising the sea floor in a bubble helmet, there is an option for you in Maunalua Bay. Ask us which one fits your group, and we will help you book the adventure.
