For large Yachts, this is done by partly submerging the steamship. The cargo is then floated over the cargo deck and when in proper position for loading, the water is pumped out, leaving the cargo on deck.
Several heavy transport vessels have been modified to serve as yacht carriers for the transportation of luxury yachts. The features of these semi-submersible yacht carriers accommodate yachts, large and small, during transport.
These yacht carriers can load and discharge using the float-on/float-off method.
After deck preparation - installation of keelblock cradles and supports to the deck of the yacht carrier - the vessel submerges into a 'floating marina' to a draft required for loading the yachts. When all yachts are moored in their reserved position, the yacht carrier starts her dock operation.
Once the deck is dry, the yachts are secured to the deck and are ready for a safe crossing. During yacht transport, the yachts are safely stowed between the yacht carriers' spray-covers, protecting them from the elements.
