The DAHET is an innovation allowing passengers to transfer easily by tenders from cruise-ships or mega-yachts towards coastal tourist sites, even in case of swell generated by wind.

Usually, when a cruise ship is anchored or at a mooring post, it faces the wind - and waves as well. However it does not move much, because of its size, whereas the tender is far more affected by the offshore agitation.

The DAHET is a device implementing a pneumatic breakwater between the incident waves and the tenders. This air bubbles curtain is generated by a system linked to the cruise ship (see drawings here-below). This way, the movements of the two ships (cruise-ship and tender) are noticeably reduced and passengers can be transfered in a safe manner.

In the case of superyachts, other applications are possible, i.e. to protect against waves the foldable platforms, the tender doors and even the sea terraces of ships, when they are close to the surface of the sea.

For existing boats, the DAHET device can be fixed to the hull, above the waterline, and then unfolded and submerged when the boat is stationary. For cruise ships or superyachts that are under design, the DAHET can be directly integrate to the bottom of the boat and therefore will be retractable during navigation.

Energy expenditures are limited because depending of the target use (short calls), there is no need to secure permanently a water surface, but only for a short period corresponding to the time required to transfer passengers from the cruise ship to the tender. Moreover, the energy is abundantly available on board of the cruise ship.

For non-equipped ships, instead of equipping directly each ship, a variant is to implement the DAHET product on a specific floating dock moored at the cruise port. Thus the dock can be used alternately by several ships anchored off the port of call, by being towed and moored alongside the cruise-ship, once it is moored by anchor or to mooring post.
