Tack about; or, a new model of a marine establishment, for raising seamen for the continual service of Her Majesty's Fleet. : Being a plain, easy,and practicable method to raise seamen upon any juncture sufficient speedily to man a very considerable fleet, and defend our trade: without the excessive charges of impress-money, impress-lieutenants, patches, or bounty-money. Most humbly recommended to Her most sacred Majesty, and the present Parliament of England. To which is added upon the same ground of establishment, a probable method to supply continual convoys to support our New-Castle trade, without the charges of wages to maintain, or raise such convoy-seamen to the government. And keep coals at a moderate price.
