Clark has a wonderful deal for all you iBoattrack afficionados! Have you favorite sailor keep the tracker aboard for the rest of the cruising season. It is only $50 a month, your sailor will spend more than that on rum. Then you will know where he/she is. On that cruising site you can see what harbor the boat is anchored in, depth soundings and all, and with the Google Earth part you can see everything in satellite and aerial photos.
Ol' Purvis there whose name is on the discussion board and Chief Sci somehow get you the whole world on your desktop. Send Clark a message..... email@example.com
