Static Draft Survey<br />
(Vessel waterline with respect to RP)<br />
Survey date: March 28, 2009<br />
Prior to conducting the patch test <strong>and</strong> survey, initial confidence checks were<br />
per<strong>for</strong>med to ensure an accurate measurement of water depths. While the Nancy Foster<br />
was tied up at Isla De Vieques the survey team initially observed the static draft of the<br />
starboard PROJ draft marks at +/-3.66m (12.0 ft.). The EM1002 transducer offset from<br />
the RP (0,0,0) is a fixed distance of 1.676m, which is entered into the installation<br />
parameters in the EM1002 controller software, Merlin V.5.2v2. The waterline to the RP<br />
is the elevation required to compensate <strong>for</strong> draft.<br />

1.68m - 3.66m = -1.98<br />
