How to Solve a Lighthouse Puzzle

Each digit on the grid represents an island lighthouse in the open sea. There are a certain number of hidden ships peppered throughout each grid, each in a single square. The digit on each lighthouse indicates how many of these ships are in the same column and row as that lighthouse, combined. No ship can touch any other ship or any lighthouse, even diagonally. Each puzzle can be solved using only spatial logic and reasoning. Good luck!
