Nurikabe Puzzle Variations

This is the first post in a series of Nurikabe variations. Nurikabe is a terrific logic puzzle from Nikolai that can be of virtually any size.  This puzzle is also known as Islands in the Stream. 
Explanation

The following are Nurikabe puzzles with extra numerical hints (Kuromasu numbers) that indicate how many numbers within a Nurikabe island are visible from that square.

The Nurikabe numbers indicating the island sizes are in bold. The hint squares are in italics and have a border to distinguish them from the Nurikabe numbers.

For more about Kuromasu puzzles themselves, click here . Kuromasu translates from Japanese as "Where is Black Cells?".

Hopefully, the sample below will clarify matters.  Please try these out and give me your feedback.
