This is going well into ASB territory along the lines of Tarranty however its something I've wondered about before- WI there was a NW passage navigatable with 16th century technology.
2 ways I've thought of doing this.
1 is outright ASB having a different America something like this
or 2 which has just sprung to mind- the warm period during which the vikings settle Greenland et all lasts longer (though this would be iffy due to probally leading to a viking settlement of NA rather then mainstream Europe)
