Google Sky Map alike to "see" continental coast ?

http://androidforums.com – I was on a sea cruise recently. I'm not very good in identifying the stars in the sky, but it was possible to use Google Sky Map on my Galaxy Note to identify what was on the sky "around" me. Sometimes I was close to the european coast, and not beeing better with geography that I am with the sky, I was wondering if there was a Google Sky Map alike for helping people like me to identify what we see on the coastal horizon ? Thanks in advance, G. (General)
