Happy New Year

Our best wishes to all our users across the world. May the tides be with you.


Tidal streams France

Tides Planner can now display tidal stream data for the Channel and Biscay coast of France. This is one of the numerous ongoing enhancements and additions to the comprehensive tides planning app. Thank you to the many users who get in touch and make suggestions.


Charts folders and AIS

We have been busy in the last few months with Charts. Among the many new features are folders for waypoints and routes, which provide a good way to store and organise planning data.

The chart sets now include SHOM charts from Brest to the border with Spain and, using the latest version of Tides Planner, currents on the French coast of the Channel and Biscay.











AIS and NMEA display immediate target data and also organise targets by time and the closest point of approach. In boats equipped with NMEA WiFi this is a really useful visual tool to passage making in busy areas such as traffic separation schemes.


Art that the tide washes away

See this article from the BBC about the amazing art of Andrés Amador, whose giant beach works get washed away by the tide.

Canada large tides at Hopewell

The Hopewell Rocks Park in Canada experience some of the largest tides in the world, at some times of the year up to a high water of 46ft. The tide has created a spectacular setting through erosion of the rocks, which can be visited en foot at low water or in a kayak tours at high water.Supervisor Kevin has used Tides Planner to devise a schedule for visitors, based on a level of 17.8ft which cuts off access to one of the coves.

Photography and tides




Malcolm of westpenwithandbeyond uses Tides Planner to arrange photographic trips at the coast. A credit to planning, patience and technique as well as a good eye for the moment.

Sailing for disadvantaged areas

East End Endeavour run from the Clyde since 2010 to create opportunities for people in socially and economically disadvantaged areas. A really good cause that runs as a not for profit organisation.

Thank you to Al who has kindly advised us on issues with visual impairment brought about by iOS7. The latest version 3.80 of Tides Planner has some additional buttons to support date changing. We are really pleased that the app can be used even with visual issues. This was the best thing we did in the whole of 2013.
