Glossary Term
Dry Docking
Dry docking is the process of taking a yacht out of the water and supporting it in a dry dock or on a slip so the underwater body and related systems can be inspected, maintained, repaired, or modified. In superyacht use, the term covers both the physical docking event and the planned yard period built around it. It is the standard window for work that cannot be completed safely or effectively afloat.
Once the yacht is dry, access opens up to hull coatings, anodes, shell openings, stabilizers, rudders, propellers, shafts, seals, thrusters, sea suctions, and underwater damage areas. IMO survey guidance ties outside-bottom inspections closely to the survey cycle and states that older ships should have the ship’s bottom inspected in dry dock rather than afloat. On classed yachts, docking and in-water surveys are part of the wider survey planning framework rather than ad hoc yard events.
A successful docking period depends on preparation long before the lift. The yard and owner’s team need current drawings, docking support information, underwater work scope, class and flag attendance planning, coating specification, and realistic access sequencing. On a major yacht refit, underwater repairs often connect to steel, mechanical, piping, paint, and survey work at the same time.
Dry docking compresses high-value work into a short and expensive window. Clear scope, correct block placement, and timely survey input usually decide whether the yacht leaves the dock with a clean underwater package or returns to service carrying avoidable punch items and deferred risk.
