"Mass attack" on tanker

Reported here:

PIRATES using fleet of nine fast speedboats attempted to board a chemical tanker sailing through the Gulf of Aden in broad daylight last Saturday. According to the latest weekly report from the ICC International Maritime Bureau, six speedboats doing 20 knots surrounded the tanker while it was underway. The master altered course, increased speed, raised the alarm and mustered the crew. Three more speedboats joined the attacking group.

The source of the report is the Wekly Piracy Report from ICC Commerical Crime Services (to Feb 20) which is found here.
