This you do submerged at depth depending on convoy speed, tracking the 'convoy spread' on hydrophone, to assess your position. Once the lead escort passes over you, you start surfacing - should bring you up approximately in the first row or just after.
The juicy targets are mid-convoy.

Small problem: the contact heading is only accurate to +/- 12.75 degrees. A contact reported as "Heading ENE" (ENE= 67.5 degrees) could have an actual heading anywhere from 56.25 to 78.75. If it takes you ten hours to reach the intercept, then the area of uncertainty is 50 km wide. Using a 16 km horizon, if you simply head straight down the reciprocal heading, there is a 30 percent chance you will make visual contact, provided the contact doesn't change course.
