Designed by ocean legends
Honu submersibles were custom-designed and built by DOER Marine and Sylvia Earle, legendary ocean scientist and advocate.
DOER has a prestigious history of submersible design, construction, and operations. Their perfect safety record has enabled countless successful dives launched from luxury yachts and world-class scientific research vessels.
