In February 2009, a mobile crane and a small piling rig appeared on site.

After ten minutes the small rig came to a stop.

Just as they turned, Murdock saw one of the small rigs at the roadblock jolt forward.

The heavy truck hit the two smaller rigs and drove them forward with scraping and tearing of metal.

Then the much heavier truck pushed the small rigs aside and was through the barricade.

"Twenty-five pounder is the smallest rig they make."

This sail was the first attempt at making a smaller rig for smaller sailors.

Murdock waited a minute; then more men came in front of the small rig, and the motor started.

"One weapons or personnel carrier, two smaller rigs," Dewitt said.

A smaller rig also represented a saving in maintenance costs.
