TDI projects in the marine industry include styling for a range of Mustang Cruisers. These include the 46ft sports fly-bridge, the 46ft sunroof and the 35ft sports cruiser. These designs involved the creation of a new super structure and interior details over existing hull designs.

For Seawind, TDI prepared concept designs for a new model designated as the Seawind 1100 catamaran. The design and cabin layout introduced sleek new styling, while retaining the functional spaciousness of the twin hull layout.
