“When I found myself at night and in unfamiliar waters, I had one friend checking the water depth with a pole and another friend looking for a boat nav app. Luckily we found Sea Drive. We were able to navigate home and I've been a Sea Drive user ever since.”
It really is like Google Maps for boating!
Depth and soundings are accurate, works well off the coast. It's the best water nav app I found.
Simple & intuitive
Sea Drive is dead simple to use and has free chart data and offline downloads. Finally a modern boat navigation app!
Fantastic App
I use Sea Drive everyday fishing in the Long Island sound, usually around Block Island or Newport. Great for tides, winds, weather. I mark all my favorite fishing spots and use the live location sharing when my buddies are out on the water. Great app. 5 stars!
