I have a Navionics navigation map chip for the Albemarle Sound area including down past Ocracoke. I sold my chart plotter that used it so now am selling the chip. Please verify it works with your chartplotter before contacting me. The chip is marked NE/US688S and I found it invaluable when navigating Albemarle Sound in my boat.

US688S - ALBEMARLE SOUND - NORFOLK AND WILLOUGHBY BAY TO OCRACOKE INLET INCLUDING CURRITUCK SOUND AND CAPE HATTERAS

$65 plus a few bucks for shipping. PM me, I may not see responses to this post.
