Herman,
Getting within a few degrees with a hand bearing compass observation only requires observing the horizon directly under the body. Sometimes the Sun produces a useful reflection on the water. If you really want a unique solution then improvise a Bris sextant out of some microscope slides that are taped together so that the bottom edge acts like a hinge. Adjust the slide spread so that the Sun reflection is visible at the horizon.

How can you do that reliable?
Is there a special compass or so for this purpose?
With a normal magnetic bearing compass you can look only a few degrees upwards
before the compassrose stalls.A compass with pelorus may works perhaps, but who has that, with a free sight
around a yacht?So who has the solution for this?
