semisubmersible
Partially submerged vessel
A semisubmersible is a vessel or platform designed to float partially submerged, with its hull below the waterline and its deck elevated above the surface on columns.
The design provides stability in rough seas.
Semisubmersible drilling rigs are common in offshore oil and gas extraction: The semisubmersible was towed to the new drilling site.
Some luxury yachts carry semisubmersible tenders.
