Some more Tetromino puzzles this week - only one of them probably needs to be called a "Battleships" puzzle as the empty grid is a more classic Tetromino puzzle. Enjoy!
Locate the indicated fleet in the grid. Each segment of a ship occupies a single cell. Ships can be rotated, but cannot be reflected. Ships do not touch each other, even diagonally. Some ship segments, or sea cells without any ship segments, may be given in the grid. The numbers on the right and bottom edges of the grid reveal the number of ship segments in that row or column.
