How far away could you spot a ship?

My group is playing skull and shackles and I was wondering what your guys' thoughts are on how far away a ship would be able to be seen on the open sea on a clear day? With or without a spyglass.

About 3 miles out is how far someone can see at sea level, according to the game mechanics. About 12 miles from the crows-nest of a 60ft mast (like most sailing ships have). I don't see any reason why someone actively searching for a ship wouldn't see it out on open waters at these ranges.


Assuming the world you're on is roughly the same size and shape as the Earth: this website might help you calculate it.

If your world has different geometry, or different laws of physics, all bets are off.

Now actually determining things about the ship would require you to be much closer. Here's how I would handle it. For instance:

Make of the Ship: Perception DC= (size mod of the ship) +1 per 10ft. So a sailing ship (Colossal: -16 size mod) could be identified by a sailor at a range of 260ft(+26 for range) by a sailor taking 10.

Ensign (flag) of the Ship: Perception DC= (size of the flag) +1 per 10ft. A War Ensign is very large, often over 20ft long (Huge: -8 size mod) and so could be identified by a sailor at a range of 180ft (+18 for range) taking 10.

I'd give a +1 perception bonus for every 10ft up the character is, so +6 in the crows-nest. Don't forget that a spyglass cuts the range penalties on perception in half.
