Large sprit rigs leave the sprit standing, and the sail is furled by brailing it up to the mast and headrope. |

In this example the two responders are positioned with identical distances to the PI Geometry sensor on the headrope. |
|
With the Simrad FS70 the rugged FS70 Trawl Unit is placed behind the headrope. |
|
If you use a second sensor behind the headrope, the difference between the two measurements will give you the height of the trawl opening. |
|
Bottom trawl: Place the sensor behind the headrope, and it will tell you the height of the trawl opening. |
|
It uses the well proven and reliable FS third wire system to establish communication between the submerged sonar head located behind the headrope and the vessel. |
|
The headrope in particular carries great significance, for it is indicative of the wearer's ability to uphold the obligations and responsibilities of manhood. |

In May and June 2011, we tested a topless trawl on a commercial trawler with a much greater headrope to footrope ratio and greater flotation than previous studies in the region. |
