Glasgow Steam Packet Co
1830 the firm G. and J. Burns in Glasgow joined with two Liverpool-based Scots, David and Charles MacIver to form the Glasgow Steam Packet Co to develop steamer services between Glasgow, Liverpool, Belfast and Londonderry.
Robert Napier engined most of their vessels running between Glasgow and Liverpool.
The success of the line led to a company in London approaching Napier for his opinion on the practicability of successfully navigating the Atlantic with steam-vessels between Liverpool and New York.
