Love this app

Have been using it for decades! Great support!

No way to delete imported tracks

Seems like there is no way to delete imported tracks. Also wish there was a way to rename them.

GREAT APP FOR BACK UP NAVIGATION

As a licensed captain this app has save me three different times in the past couple years. I was in some real hairy predicaments and having plotter trouble, the SEA IQ was a life saver giving me information I needed to navigate safely out of certain predicaments. I highly recommend every captain download the app on their smart phones if you want to feel secure in case your GPS plotter lets you down!

Our main charting tool

Although we have a full electronics suite in our trawler, when cruising , our primary charting tool is SEAiq on an iPad. The updated charts with the AIS target overlay are invaluable to us and we found this program to be one of the best bangs for the buck!

Paper Charts

I have SEAiq USA on two iPad Pro 12.9” devices, one primary one backup. I supplement them with a chartplotter. I do not carry paper charts, which are out-of-date the moment ink hits paper.

I can hear the β€œgotta have paper” crowd howling, but for the last several years of a career flying a 400,000 pound jet all over the U.S., in the cockpit for charts were two off-the-shelf iPads, one for the captain, one for the first officer. We also had two moving maps that are roughly analogous to a chartplotter. So if you’re a paper purist, don’t get on a commercial jet. There will be no paper.
