The name implies that you come back to the dock with dirty ice, meaning you have fish blood in the box of previously clean ice. My thoughts are to incorporate a mermaid on the left casting a fishing line over the whole name with a yellowfin tuna on the other end of the line. Perhaps the yellowfin tuna can make the word "ice" bloody. Maybe the fishing line can cross the "T" in the word "Dirty". I am visualizing the word Dirty in script and the word ice in blocky "frozen" type bloody lettering. If the bloody part is too difficult then we can eliminate it from the logo and make the whole thing script, or still use block lettering but without the blood. This is just my vision but i am wide open to whatever concepts you come up with too. The surface the logo is being applied to is white. The sides of the boat are sky blue on top and navy blue on bottom. The area across the back of the boat where the logo will be applied is approximately 10 ft wide x 1' 6" tall and is a white background.
