Rules: Place each ship in the given fleet in the grid, one ship segment per cell, such that no two ships touch, even diagonally. A clue tells how many ship segments there are on that row or column, and unclued rows and columns may have any number of segments.
Some puzzles have some ship segments already placed in the grid: the shape tells whether it’s a single-cell ship, a middle segment or an end segment. Cells with waves in them are empty.
The standard ten-ship fleet is given below. The puzzle above uses a six-ship fleet with one ship of length 3, two ships of length 2 and three ships of length 1.
