[Rules] River Battleships rules clarifying

[Juiceman]

It is in 17.4 Boat Movement, last bullet point.

Phew, thank you! I don't know how I lost it 

Anyway it means that in scenarios with depth=3 grounding is impossible, because 1+3-2=2. It's the lowest possible die result. So even a boat pushed to the river bank by Current cannot be grounded

It is easy to miss, yes to the depth of 3 & draft of two, read 17.44 Grounding third paragraph.
