There is disclosed in a surface effect ship which is constructed substantially of aluminum alloy material a hull construction including a side hull component which is bottomed by an operationally "wet" aluminum alloy keel plate, an improved propeller support arrangement comprising a superior strength thin-profile steel alloy strut extending cantilever-wise through the keel plate and carrying at its outer end bearing means for support of a ship propeller shaft. Interiorly of the side hull the steel strut is mechanically anchored to an operationally "dry" aluminum alloy member of the side hull structure, while at its underwater "wet" intersection with the aluminum alloy keel plate it is supported thereby but electrolytically and dynamically insulated therefrom by means of an epoxy-like housing device which at that cantilever support juncture encircles the strut. |
