S844 appears to be the principal funnel design. Some vessels have a narrow black top, as on Stirling Esk in June 2003; website photographs may show red or possibly orange tops, but are too small for certainty.

Putford Terminator retains a Putford black funnel without the band, carrying the Seacor logo. The other Stirling Offshore vessel, Putford Provider, uses the B626 funnel also found on some Boston Putford vessels.

Putford Vogager, photographed on 7 August 2006 and listed under Seacor Marine (International) and Southern North Sea, has this further variation.
