He was very generous to his native land. Soon after the war ended he established a schoolship in Massachusetts waters, for mates and skippers to learn the art of navigation. The barge Clio which he purchased for the purpose, was commanded by his kinsman, Captain Hector Coffin, who was imprudent enough in 1826 to go up in her to Quebec with the American flag flying and act in a very indiscreet manner, and when his brother, General John Coffin, of New Brunswick, urged him to abandon what gave umbrage at home, he acquiesced in giving up what had cost him several thousand pounds. He also sent over to the land of his birth famous race horses and cattle to improve the breed; also fish, rare fruit and plants. He was warmly attached to Nantucket, where his ancestors and their descendants had dwelt for many generations. He visited the place and became acquainted with his kinsfolk and in 1826 appropriated $12,000 afterwards increased till now it is upwards of $60,000, as a fund for a school for the instruction of the posterity of Tristram. This includes nearly every native born child of the island. The Duke of Clarence, William the Fourth, who succeeded his brother George to the throne, through his long connection with the navy, attached to him the officers who had grown old with him. It is said the King had Sir Isaac upon his list as Earl of Magdalen and intended to make him Governor of Canada, and the only obstacle that prevented it was the attachment he had for the land of his birth. This memoir of a Boston boy, who by dint of his own native energy attained a title, and the highest rank in the British navy, and a generous benefactor, whose works still bear witness to the noble impulse that prompted them, will ever be kindly remembered and cherished by his countrymen. Jonathan Perry Coffin, Sir Isaac's youngest brother, born in Boston in 1762, was a barrister of repute in London.
