Here is what the rules say:
'The fleet then can move to a location next to or on top of hexes that can be invaded. Any hex that has water on it can be invaded. Full land hexes can’t be invaded. Hexes in which more of the hex is water are coastal hexes. Hexes in which there is more land than water are land hexes. Disembarking is unloading on a friendly hex that meets the criteria for an invasion.'
1. So the first line seems incorrect, I can only get an invasion if I move onto a valid invasion hex, next to one won't do it.
2. As far as I can see 'full land hexes' and 'Hexes in which there is more land than water are land hexes' are the same thing, so using the word 'full' is confusing.
Did a test and moved an axis unit out to sea, this map is what I get for possible invasion hexes.
3. Some hexes are identified as 'beach' when you curser over them, should they not be identified as 'plains (clear)' because 'beach' doesn't really identify which hexes can be invaded.
