Float-on, Float-off, how does it work?

Our semi-submersibles are exciting vessels. With a unique float-on/float-off loading method, they have a transatlantic delivery time of 15 days average while carrying yachts up to 165m (541ft), loaded in impressive numbers on the carrier’s dock. The vessel is submerged into a floating marina that allows for easy loading. When all yachts are moored in 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 transportation, the yachts are safely stowed between the yacht carriers’ spray-covers, protecting them from the elements.

From the moment you contact DYT to the booking of your yacht transport, our DYT team works together to provide a service to suit your needs. When the planned date of transport arrives, you will have received comprehensive details about what you can expect from us and about what we require from you.

Stow-plans showing the on-deck position of each yacht are arranged well in advance. This allows the deck of our ship to be prepared with the required cradles, fixtures and fittings before arrival at the designated harbor.

Upon arrival the vessel is prepared for semi-submersion. Ballast tanks are flooded which submerge the ship to the required depth in preparation for the FLO/FLO loading of your yacht. The specific amount of ballast required is carefully calculated based on maximum yacht draft and maximum cradle height ensuring safe FLO/FLO loading of all yachts.

Once loading is complete yachts will be given the instruction to switch off all engines and generators. The vessel stern door is then closed before our DYT divers can safely enter the water and begin their checks. Divers check all cradles are ready to receive their respective yachts. Divers remain in the water as de-ballasting begins, ensuring cradles remain in position as each yacht descends and is secured into position. Once the vessel deck is dry our divers and loadmaster check all cradles and dockings alongside crew and shore teams. These final safety checks are an essential part of the loading process and teamwork at DYT.

Upon arrival at the next destination the ship is once again submerged to allow our DYT loadmaster to oversee and direct the unloading of all yachts using the FLO/FLO system.

And off you go, broadening your horizons.
