Hello friends.
After weeks of hard work I moved yesterday.

This morning I woke up with a brilliant view. I can see the horizon over a width of 50 kilometers. This is possible because the Netherlands is very flat.
I start again with the upload of landscapes.

Hi Herman,

Welcome back!
This looks awesome!!

Can´t wait to see more from your view.

I would like to check it out myself someday, if that´s alright with you!
Fred

Hi Herman,

Welcome Back!!!!


Marty

Hi Herman,
... was missing you
Werner

Yep Herman, I was missing you too
Welcome back!


I know if you stand in front of the sea and look to the horizon you can see 5 km maximum. Because the Earth is round.
But 50 km is way too far.
My city - Saint-Petersburg is also completely flat.
It was literally built on a swamp.

Hi Pasha,
here a list of geometrical visibility in different eye hights
(This knowledge is very important for us sailors)

1 m 3,6 km
2 m 5,0 km
3 m 6,1 km
4 m 7,1 km
5 m 8,0 km
6 m 8,7 km
7 m 9,4 km
8 m 10,0 km

So you are right with the visibility of 5 km ... but Herman is also right, because he wrote horizontal width

Werner

Hi everyone

So Werner you are right. I see 25km left and 25 km right
