BOSKALIS.

The flag is common to the group. Nüsse’s old and new website versions differ in the blue shade; the house flag is also documented for Bos & Kalis at Sliedrecht, later Papendrecht.

The later flag adds a white stylised crown and the company name in the lower-hoist blue triangle. A specimen offered in December 2007 measured 0.90 × 1.40 m. Jan Mertens reported in April 2008 that most of the fleet would transfer to the Cyprus flag while the Dutch company retained its Papendrecht seat; the vessels had previously used eight flags.

The funnel follows portside and starboard photographs of Seaway, dated July 2003 and 16 November 2012.
