The basic blueprint for the Sigma Patrol Series can change since each hull segment is crafted as a distinct component. Vessels can differ in the number of hull segments and how they're arranged. Sigma represents Ship Integrated Geometrical Modularity Approach. The ship's primary measurements are specified within its own designation, SIGMA 9113 signifies 91 meters (298 ft 7 in) long with a beam of 13 meters (42 ft 8 in). Similarly, the SIGMA 10513 is 105 meters (344 ft 6 in) in length with a beam of 13 meters. The design was born from the earlier High Speed Displacement hull form created by MARIN Teknikk AS back in the 1970s.
