We are constructing a field to practice on. I cannot find the exact height of the beam on both ends in the field drawings, or the angle of the beam. It gives the height of the gyres, so are we supposed to guess how high to put the beam.??

See Q&A # 30 for Height at top. as well as notice the  2" tolerance.
For the original beam position, the angle of the beam is 5 degrees slope from horizontal in the middle of beam.   Since the beam sags, the slope will be 6-8 degrees at top, and 3-5 degrees at bottom.
For the "Current Surge" advance challenge, the drawings show the Z delta of the lower end, and you can use trigonometry to find the new angle.

I agree it would have been nice to have a few relative numbers like "beam to eyebolt" and "beam edge to gyre".   You can use the 3d viewer to find these numbers, but we were warned that the viewer may not exactly match the drawings, (or the field as built.)
   The ocean is an imperfectly predictable and difficult environment.
