New Feature: Waterway Guide

Waterway Guide content is now available as a chart overlay within the SEAiq app. Waterway Guide utilizes their extensive user base, large network of on-the-water editors, and full-time staff to provide up-to-date and accurate content for safe and informed travel along the waterways. Marinas, anchorages, navigation alerts, bridges and locks for the Eastern U.S., Canada, Bahamas, and Cuba are now available for offline access.

Important: ActiveCaptain

We are informed on May 23, 2018 Garmin will make incompatible changes to the ActiveCaptain server. After this date, the current ActiveCaptain data will continue to work in SEAiq. However, no further updates will be available for download. We recommend users sync offline data on their devices before the May 23 cut-off. We are considering updating SEAiq support for ActiveCaptain but do not have definite plans yet.

IOS 11 WiFi Issues (Last Updated 14 Nov 2017)

Update (10 Dec 2017): Users who update to IOS 11 are still reporting these issues. If you choose to update, please do so when you have ample time to resolve the issues described below. For owners of PilotsTech devices, you may need to replace your Pilotstech device. Consider purchasing a spare before upgrading to IOS 11.

Some users who have upgraded to IOS 11 have reported issues with connecting to their WiFi based AIS pilot plugs. IOS 11 is a major software release for Apple and includes many changes. We understand that Apple is actively working to address the many issues that have arisen in this release.

We normally find that the Apple IOS updates usually are quite reliable and do not cause issues. As a general rule, however, recommended best practice is to not update to new IOS releases on your iPad immediately after the release. For IOS 11, we recommend not updating at all until Apple has stabilized the release further and these issues are resolved.

To our knowledge, the issue is one of compatibility between IOS 11 and the AIS WiFi devices. We are not aware of any way in which SEAiq is contributing or causing the problem. No changes have been made to SEAiq networking in the recent past.

Important: please email us the results (positive/negative) of following the suggestions in this document. This will help us to update the recommendations as we have more information.

Affected Devices

Only some iPad users appear to be affected by this issue. We have received confirmation from many IOS users that they have upgraded to IOS 11 and not had any issues.

  • Most of the reports have been users with PilotsTech AW2016 devices and similar models. PilotsTech indicates that the issue with their devices may be limited to older models.
  • We have received one report of issues with some Trelleborg CAT ROT. Trelleborg has indicated they have received any problem reports (as of 28 Sept 2017).


Reports of issues include the following types of symptoms:

  • iPad is unable to connect to WiFi network
  • Connection to WiFi network seems unstable
  • WiFi network password has to be repeatedly re-entered

Possible Resolutions and Best Practices

Below are possible steps to resolve the issues. Some of these were recommended/approved by PilotsTech for addressing problems with their devices.

  • For users who have not upgraded to IOS 11, we recommend not doing so and staying at the current release until these issues are resolved. We will post here when we believe it is appropriate to upgrade to IOS 11.
  • If you have upgraded to IOS 11, it is normally not possible to downgrade to an earlier version of IOS, because of how Apple security/installation/upgrade works. Apple has already started making patch releases (currently IOS 11.0.2) and if you continue to have issues, you may choose to update to those since they should normally only improve the situation. We can not make guarantees about IOS patch release updates and there is the possibility that IOS patch release could cause a regression.
