Hi Richard,

This is my pet theory. The greatest variable I face in my day to day observations is the quality of the horizon. I am afraid that I don't think that I made any specific threads on it, but if you search my entries, you will find my discussions.

You can certainly be seeing the effects of vog or perhaps your HoE is a bit high so you are trying to observe a horizon that is very far off and therefore affected by the humidity.

I would try to either get closer to shore, and if you have already done so, go to a different beach away from the volcano to try and get better horizons. Unfortunately in the tropics, you may not find one no matter which way you look.

At sea I find different quality horizons at different azimuths at the same time, and my sights can show it even in the same round of sights.

My next step will be to take my camera and see if I can't get photographs of different horizon qualities, and make some sort of rule of thumb scale to use for sight confidence.

Jeremy
