  • Scenic cruising through the Middle Keys
  • Time for snorkeling, relaxing, and sightseeing
  • A route based on weather, visibility, and water conditions
  • A more comfortable alternative to a crowded snorkel boat

Demise Charter Benefits with SeaEO

  • Your Day, Your Way

    You control the voyage on your charter and dictate your dream day, not our company, allowing for multiple activities not just a specific one and a day filled with your dream itinerary.

  • Only The Best Captains

    Being we don't employ the captains directly, we open ourselves to not being tied to someone. We only select the top captains in the area to put on our pre-approved list, which leaves you the selection of the best captains in the area to join your charterers. 

  • Large Charter Capacity

    Due to the foreign built vessels SeaEO exclusively uses, it forces the largest allowable non-COI charter capacity. That allows you, the crew, and 12 of your guests to join you on your voyage!

Do we need snorkeling experience?

No. Many guests are new to snorkeling. The experience can be adjusted based on your group’s comfort level and the day’s conditions.

Where will we snorkel?

The exact snorkeling area depends on weather, visibility, tides, and water conditions. Marathon is known for access to reef areas and clear Middle Keys waters.

Is Sombrero Reef nearby?

Yes. Sombrero Reef is one of the well-known snorkeling areas near Marathon, though the final route depends on conditions and trip planning.

What should we bring?
