A study of the geometrical principles of doubly curved surfaces found in rowing shells.  Beginning with analysis of the sequential evolution of the shaping of structural bulkheads within a kingfisher shell, similar techniques are then applied to generate customized doubly curved surfaces through the process of lamination.

The sequential evolution of a modified bulkhead profile generates customized doubly curved surfaces by arraying flat sections.  A rigorous system of geometric operations is implemented to produce compelling spatial forms viewed in section. 

Geometrical analysis of motion through time of a rowing scull carried from racks to the dock edge of Penn's Schuylkill River boathouse.  Resulting profile curves provide a geometric system of operations for the production of a doubly curved surface to serve as the roof for a boathouse design positioned upriver.
