This Northern Caravel was a type of evolved British Round Ship, 3/1 wide (three widths for a length). It had to be around 35 meters for 12 meters wide at the waterline, with 3 decks, and of clinker construction (overlapping riveted planks), all in oak. Its rigging integrated a main sail, upper sail, bowsprit with civadier typical of late medieval Cogs and latin sail on its rear mast. Recent reconstruction of a discovery ship in Bristol sailed by John Cabot in 1497 from Bristol to North America.
