Re: I want a nautical tattoo :)
I don't have any tattoos and don't condone them, though my wife is a fan though she doesn't have any either.
My suggestion would be to use a non-toxic light-fast pigment ink, so that it's color is maintained over time, and it doesn't do you any harm. For black there is carbon-black ink, in which the oldest manuscripts in the world are written, I believe from China, non-toxic ones are available such as speedball super black. It's made from carbon, and other than water we're carbon-based life-forms so is quite safe.
For blue, I don't really know any completely-safe ones, though Phthalocyanine Blue is probably your best bet.
