Superstructure concepts

Our standard MODCAT designs, when assembled on site, provides a ready to use main deck which can be used as supplied or enclosed for crew and passenger comfort. Our clients can select a existing structure or request a new design superstructure from our Manufacturing plant which can be supplied with their Modcat modules.


Before the MODCAT modules are constructed, the client has access to a variety of Superstructure designs to house the required steering, propulsion, bilge pump, marine instrumentation, marine radios, entertainment systems, and deck equipment controls. These are married to the MODCAT by means of hard points, which are added to the Sponsons, Pontoons, deck assembly and deck plating once the layout and deck equipment is selected.


Our Marine Yard is in a position to design and incorporate above deck structures that can be securely mounted onto the MODCAT to meet our client’s requirements.

We can provide advice and assistance prior to compiling construction drawings for individual client superstructure requirements.

Internal superstructure - wheelhouse fit out options

MODCAT owners have the option to fit out their MODCAT according to their Budget and preference.


This can be done, either at our works, or personally once assembled prior to the vessel being launched.

These can be concluded at a cost that can be included in the clients total package cost once the scope required has been clarified.
