24 Jan 2005 - Info from Ben Onderwater: "Dolfijn blows mainballast tanks 1 port and starboard, normally done to get more buoyancy prior to departure there air leaks ventilate the ballast tanks over time (for instance longer periods docked in a harbour) now it is done due to it's spectacular sight thus for fun!"
