Preface and setting
The narrative, framed in an early‑eighteenth‑century North American preface, situates itself in the culturally young, commercially favoured colonies—especially the Dutch legacy of New York—and emphasizes moral progress, mixed origins, and civic duty. Action centers on Manhattan and the Raritan estuary in the 1710s, where mercantile prudence, landed interest, and naval obligation intersect.

Principal figures and milieu
Key figures include Alderman Myndert Van Beverout, a thrifty Dutch burgher and guardian; Alida de Barbérie, a cultivated Huguenot heiress; Oloff Van Staats, the sober Patroon; Captain Cornelius Ludlow, commander of the royal sloop Coquette; François, Alida’s valet; several Black servants who colour domestic life; and a mysterious free‑trader appearing as Seadrift, Master Tiller, and the “Skimmer of the Seas,” captain of the swift brigantine Water‑Witch. The brigantine’s crew and its theatrical artifices (false lights, a sea‑green female effigy, an oracle‑book bearing Shakespearean mottoes) repeatedly challenge local respectability and law.

Plot outline
The early episodes portray quotidian colonial rituals and establish social ties. During a country excursion Van Beverout, Alida, and companions encounter a striking stranger who provokes Captain Ludlow and later courts Alida. The Water‑Witch, anchored in concealed inlets, personifies the paradox of elegance and contraband: genteel trappings masking illicit trade. Negotiations and suspicions expose the tension between mercantile opportunism and official duty; Ludlow’s professional remit to suppress smuggling conflicts with his private attachment to Alida.

Maritime conflict and pursuit
A sequence of maritime episodes dramatizes repeated elusiveness: the brigantine lures and outwits the Coquette with false lights, rapid changes of rig, and mastery of shoals and currents (Blackwell’s, the Narrows, Hell‑Gate). Multiple boarding attempts and night chases fail; the Coquette survives a squall and several encounters but cannot decisively capture the Water‑Witch. The brigantine’s leader alternates between cultured charm and outlaw bravado, complicating moral judgment.

Crisis, catastrophe, and resolution
The climax brings direct combat: French boats attack the Coquette; fierce close‑quarters fighting ensues, veteran Trysail is mortally wounded, and fire ignites belowdecks. Panic and breakdown of discipline follow; explosions destroy the Coquette. Survivors improvise a raft and endure a harrowing night before the Water‑Witch unexpectedly rescues them. The Skimmer reveals documentary proof that Eudora—thought his sister and in Van Beverout’s care—is actually the Alderman’s legitimate daughter. Eudora chooses the brigantine life and departs with the Skimmer; Ludlow and Alida marry amid melancholy. The Water‑Witch vanishes, leaving questions of honor, legality, and attachment unsettled.

Themes and technique
The work juxtaposes commerce and conscience, seamanship and subterfuge, masculine honor and feminine agency. Detailed nautical procedure and staged rituals lend maritime realism and an atmosphere of providence and superstition, while the moral ambiguity of the Skimmer complicates neat resolutions, producing a finale of reconciliation tempered by loss.
