Nurikabe Battleships (1001)

Instruction:
Shade some empty (non-numbered) cells (leaving the other cells white) so that the grid is divided into nonoverlapping regions; cells of the same color are considered in the same region if they are adjacent along edges. Each given number must be in a white region that has the same area in cells as that number. Each white region must have exactly one given number. All shaded cells must be in the same region. No 2×2 group of cells can be entirely shaded.
Locate the indicated fleet of ships in the grid. Ships may be rotated before being placed in the grid. Each piece of a ship occupies a single cell. Ships do not touch each other, not even diagonally (that is, if two ship pieces are cells that share an edge or a corner, they must be part of the same ship). Each number to the top and left of the grid reveals the number of ship pieces that must be located in that row or column.
Ship pieces may not be in white (unshaded) regions.
