Is there a safe place to store my belongings while on tour?
  • The only type of storage available is the space around your seating area. There will always be one crew member on board at all times, so it is advised that you keep your belongings with you rather then leaving them in your car.
Can we get back on the boat at any time if the water gets cold?
  • Yes, absolutely.
How is the underwater visibility?
  • Visibility is great. The Manta Rays will sometimes be within inches of you and the water is only 20~30 feet in depth, so visibility is normally quite clear.
Will wet suits be provided?
  • Yes, wet suits will be provided.
What kind of boat will be used?
  • Built in 2005, it is a new 55' Teknicraft Catamaran which has been designed and built to accommodate guests who seek the very best in luxury, comfort and technology. The new vessel seats 42 passengers. It is equipped with two stairways for easy access in and out of the water, full bar & galley, two restrooms and fresh water showers.

  • No. All parties have at least one member who is 18 years old or older.
