SEAiq Pilot is designed especially for use by river, channel, and harbor pilots. It includes support for charts in the S-57, S-63, iENC and BSB/KAP formats and use of external NMEA/AIS over WiFi.

IMPORTANT: For non-pilots, we recommend SEAiq and SEAiq USA.

This app is free to download. All features are available during a 7-day evaluation period. An in-app purchase is required to permanently upgrade the app, otherwise after the evaluation period only basic chart viewing is supported.

Features unique to SEAiq Pilot include:
* Support for official HO S-57/S-63 marine charts
* Adheres to IHO S-52 chart display standards
* Predicted vessel display (with ROT)
* Docking aids displaying distance/velocity to wharf fenders
* Vessel catalog
* Supports WiFi based AIS plugs and Portable Pilot Units
* NMEA/AIS record and playback
* Waypoints, routes, ETA, XTD, speed limits
* Route Meeting Point
* Visual CPA
* AIS "virtual boarding"

Continued use of GPS running in the background can dramatically decrease battery life.

Best ipad navigation App for pilots


I'm a pilot in the Great Lakes, and use this app for all waters - from open Lakes to narrow confined rivers and harbors. I've used a of the available apps, and always used a laptop PPU because it had all of the features that I need. This app is now all I use. Coupled with a rate of turn generator, it shows rate of turn vectors and gives me all of the information that my laptop PPU provides. The AIS information is second to none. This is the only app that I've found that provides information as to whether a target will pass ahead or astern of you. Simple, but important information to me. I'd recommend this app to any professional that wants to have the features of a laptop PPU, but with a power on to navigating time of less that a minute. Great App!

Best professional navigational software App available


I am a Southeast Alaska Marine Pilot, I have been using Navigation software since 1988, SEAiq Pilot has all the features found in the the best PPU software I have used. The developer is extremely easy to work with, knowledgeable, and has a can do attitude. I gave him a page long wish list of things I would like to see in a professional navigation program, he accomplished them in a two week period. The same things have been requested of the $4000 + software with no results after 5 or more years. I will be recommending this to all my pilot colleagues. This is the best $200 that I have ever spent for navigation software. If I could give it 10 stars, I would, it's that good! Captain Bob Winter

Best NAV AP ever


I'm a professional mariner & move ships of all sizes for a living. So with this in mind I've been using NAV programs for decades now & find SEAiq not only performs better than others I've used in the past but is also extremely "user friendly". I have it installed on a dedicated "work iPad" & love how I can board a vessel & it turns on & connects to my Pilot Port transmitter instantly. Plus it just keeps getting better with each update, love it!
