This social network graph links relationships between ship owners or charterers and skippers. Use the zoom tool in the upper right to enlarge. Owners/charterers are indicated in red, skippers are shown in blue, and larger dots signify higher numbers of interactions. The clustering of skippers around various owners or charterers indicates that, rather than drawing from a shared community of skippers, voyage outfitters worked with selected groups. Owners and outfitters, such as the Verbrugge family merchant group, sometimes utilized the same skipper for several voyages (see Tables: A Family Sailing Hierarchy). This was surely meant to add security to business dealings by engaging familiar and trusted principals for the sea arm of the undertaking.
