Additional Tour Info

Our fleet

Our fleet consists of 3 custom made aluminum hull boats and 1 Anderson boat. The 42 foot “Abunai”, the 35 foot “Kaiou” and the 35 foot “Isao” are equipped with covered, cushioned seating for passenger comfort. Our trusty 32 foot Anderson boat “Anela” is our fourth vessel.


Safety is our first concern. We begin each tour with an informative safety briefing followed by a brief history of our tour. Here’s where you’ll understand how were able to guaranty sightings.

What to Bring

If you know you have motion sickness or believe you will have motion sickness, please take precautions the day before your shark tour and again one hour before the tour. We provide masks, snorkels, and cold drinking water. We encourage you to bring towels, swimwear, change of clothes, a hat, sunglasses, eco-friendly suntan lotion, backpack, snacks, still and video camera, and your own mask and snorkel if you want to. We have available to purchase underwater cameras and a video service shot in 1080p. You’ll be able to get the best shots possible.


In Hawaii for majority of the year, the winds are at its calmest at the beginning of the day and gently progresses throughout. To take advantage of the calmer morning conditions, we operate our morning tours first before opening later tours. If you’re only able to make an afternoon appointment, please call or email us for recommendations. We’ll see sharks no matter what time of day, or you don’t pay.
