Navigation program

A real navigation program worth far more than its $8.00 cost. A bit tedious loading NOAA charts, but well worth the required effort. Used on recent yacht delivery on St Johns River Florida USA with perfect results. The up to date marked charts big help. Kept me and my crew on track through somewhat complex unfamiliar waters. Prevented two near groundings. Every boater with an I phone should have this program. Perfect for small boats with no other navigation equipment. Shows "course/up" and can be used by anyone with basic boating course qualifications. I hold a US Coast Guard 100 Ton Masters License.
