ABSTRACT:
A structural vessel includes helically curved inner and outer spaced strips of material each having a plurality of helical turns, with contiguous edges of each two successive turns of the inner and outer strips being seamed together, and a helically curved structural beam disposed between the strips and secured thereto along their turns. A floatable work housing is provided for vessel fabrication, the housing having a sealed opening through which the completed portion of the vessel progressively extends and is floated on a body of water to avoid a need for external supports and bearings.
