It's not often a pair of billionaires' yachts are docked in the islands.
At Kewalo Basin, Larry Ellison's Rising Sun was just across the water from...
... Google co-founder Larry Page's mega-ship Senses.
The Rising Sun is more than twice the length of Senses, but Page's 193-foot yacht comes with a helipad and chopper.
Wednesday afternoon, barrels of aviation fuel for that helicopter were being loaded onto the ship when dozens of gallons were spilled.
The fuel stayed on the surface of the water, but sent a gaseous stench across the harbor and brought emergency crews out.
Because of the southerly winds, the noxious odor was sent directly over to Ellison's mega-ship.
There was no determination on why the fuel spilled, but one yacht ended up making a big stink for the other.
Once it was determined the was no danger of the spilled fuel catching on fire, the cleanup began.
Crews were sent out into the water to mop up the fuel floating on the surface.
Absorbent materials were placed around the Rising Sun.
Specially-trained personnel were also brought in to get to fuel that floated under docks and parking areas.
Whomever causes the spill is responsible for the cost of cleaning up.
So, along with paying for the cleanup of the harbor...
... Google's Page may have to write a check to Ellison for the mess.
