HOW TOS Tap Help in the app. Online Manual: isailgps.com Email developer: lwjames@isailgps.com RASTER CHARTS VS. VECTOR CHARTS The National Oceanic & Atmospheric Administration has provided both RNC (raster) & ENC (vector) charts. The great advantage of the high resolution RNC charts used by iSailGPS is the high level of detail produced by professional cartographers that is unobtainable on any vector-based chart. These RNC Charts differ from vector charts in that each chart covers a specific area, just as paper nautical charts do. Switches automatically to a new chart when your boat leaves the area covered by the previous chart. For most locations, there are multiple charts at different scales with different levels of detail & areas of coverage. Paper charts can have multiple panels, each showing a different area or scale. Each digital panel is individually displayed by iSailGPS with a north-up orientation. iSail GPS is priced to make it readily available to all boating enthusiasts. Winner of the Practical Sailor Editors’ Choice Award. DEVICE REQUIREMENTS Use iSailGPS on any iOS device even if you don't have a cellular data plan for it. iPhones & WiFi+cellular iPads support full navigation. For WiFi-only iPads & iPod touch, an iOS-compatible external GPS receiver is required to show your location on the water & record tracks. However, you can view charts using the iOS device alone.
