For the same reason that blue jeans are blue: The dye is relatively cheap and very stable in the sunlight.
You'll find that each color of dyes is usually based on one chemistry, and besides cost and durability, the type of chemistry also causes "dye embrittlement" which can make the cloth weaker too. Reds and yellow bleach out quickly, red embrittles fabric (probably because it absorbs so much energy from the sunlight, which is why it breaks down and bleaches out) yellow fades quickly, blues and greens seem to be the most stable and economical. Black is simply "the hottest" and, technically, not a color. Especially once it fades to something else. And of course beige is, well, beige.
As Caleb says, you would never actually paint a boat blue. In Greece and the med, they say blue is the color of Neptune and Poseidon, and that if you use his color on your bride--he may get jealous and take her. (Captains were formally wed to their boats, which were christened as daughters of the sea, so that the sea gods would protect them, and their captains.)
Never take a chance on pissing off a sea god.
Now, can I interest you in something new from Vera Wang? In a nice sequined gold lamé perhaps? Very attractive in a light breeze.[g]
