SLEEPDIENST B. ISKES & ZOON B.V.

Sirius photographed on 10 June 2009 provides I313. The flag’s upper arc reads ISKES TOWAGE & SALVAGE followed by uncertain letters taken as BV, though CO is possible. IJMUIDEN appears below the tow-rope emblem, whose colouring differs slightly from the logo.

A photograph of Sirius and Saturnus on the same date shows Saturnus without an emblem on its funnel bands and apparently flying the pennant version as its main flag. A fold could instead make the rectangular flag look pointed, but the charges seem nearer the hoist, supporting the pennant interpretation. Brent is shown flying the pennant as a bow jack on the company website.

I315 is based on Tumak’s starboard side on 28 March 2010.
