[1] Gulliver and his gang ran fifteen luggers to transport gin, silk, lace and tea from the Continent to Poole Bay[2] and came to control the coast from Lymington on The Solent in Hampshire, through Dorset to Torbay in Devon.
[2][better source needed] He owned several farms, including one at Eggardon Hill in Dorset where he planted large clumps of trees to act as navigation aids for his ships.
He retired to Gulliver's House, West Borough, Wimborne and died there on 13 September 1822, leaving an estate of £60,000, with properties across Hampshire, Wiltshire, Somerset and Dorset.
Gulliver's only son, Isaac (1774–98) died unmarried, but his daughters married into the Fryer family whose interests and wealth ranged from the Newfoundland fisheries to banking.
[6] Willibald Alexis's historical romance Walladmor (1823) includes a smuggler character whom the novel's English translator Thomas De Quincey recognized as based on Isaac Gulliver.
