SeaClear Navigation Software
SeaClear is a free PC based chart plotting system for Windows. With a GPS connected SeaClear displays your current position, speed, heading and other data on the screen. The chart scrolls automatically and new charts are loaded before you sail off the edge. Tracks may be saved to file for later reviewing and log book entries can be made manually and automatically. Unlimited number of routes and waypoints can be created and used to assist navigation.
SeaClear can also interface with an Automatic Identification System (AIS) receiver and display the position of vessels transmitting AIS data. You can set up guard zones, plot closest point of approach and much more.
SeaClear makes very efficient use of memory and runs happily on low end laptops and notebook computers. It can even run on Linux based operating systems, eg. Ubuntu, running Windows emulation software such as Wine.

There is also an active SeaClear users group on Yahoo where the answers to most questions can be found: SeaClear Users Group.
UK Marine Charts
Up until recently the only way to import your UKHO Admiralty charts into SeaClear was by scanning them, usually in sections, and then converting the graphics image into the SeaClear .WCI chart format. The process is both difficult and time-consuming unless you have access to a full-size scanner. Fortunately there is a better way.
Go to Visit My Harbour and buy either the DVD or usb dongle with both SeaClear software and over 800 UK charts. That's 400+ full scale, up-to-date Admiralty charts, fully licenced for navigation, plus another 400 or so harbour plans and chartlets. You will not find a better electronic chart package anywhere.
For those of you who were searching for a method to import Memory-Map Marine Charts into SeaClear, sorry, but the procedure has been removed from this site. The Visit My Harbour DVD and usb dongle have made it entirely redundant.
