## What is River Thames Guide?

The complete planner and guide for travel and leisure on the River Thames (from its source to the Thames Barrier) and the Wey Navigation including where you can go, how you get there and what’s on the way - includes these key features:

Thames Map and Guide:
•Interactive River Map: self-contained - no internet connection needed
•Journey Planner: time (at 5, 3 , 1 mph), distance and number of locks between any two of 102 River Thames points (45 on Wey)

Boating Advice:

INTERACTIVE RIVER MAP:  pinch or squeeze to zoom to the required level of detail. Add any combination of locks, moorings, boatyards, fuel, marinas, pubs, restaurants, lodgings, sanitation, fishing, emergency RVP and/or bridges; tapping any icon pops up further details including phone number, post code, maximum stay etc  (where available). The interactive map is built-in to the App so you do not need an Internet connection to see where you are and facilities near you (PLEASE NOTE: this means a large download - please be patient, it’s worth it!).

JOURNEY PLANNER: select a starting point and destination from the supplied list of 102 landmarks (including locks, marinas, moorings, bridges  and places of interest (from Lechlade to the Thames Barrier) and immediately see the sailing distance, direction (up or downstream), sailing time (at 5 mph, 3 mph and 1 mph) and the number of locks to transit to complete your journey; Wey navigation planner features 45 locations.

LOCK FEATURES: every Thames lock is listed in order from Cricklade Bridge to Teddington with distance to next lock both up and downstream. Touch any lock to see much more information including: telephone number; post code; lock type; width, drop and length; lock keeper’s hours; facilities available (such as WC, water, pump out etc). From the lock detail just tap to highlight this lock in the middle of the interactive map.  Portage Maps for Sonning to Teddington locks.

BRIDGE HEADWAY: every bridge listed in order with headway in feet and metres; bridge headways are colour coded for ease of use and instant check to see if you need to lower any masts.

All the above features are built-in so are available even without an Internet connection.

WEATHER: select one of 20 location on the river for an up-to-date weather forecast for today and tomorrow (includes temperature, winds, humidity, visibility, sunrise and sunset). Requires an Internet connection. The weather page includes the current nautical twilight (the correct time to strike your ensign).

CURRENT RIVER CONDITIONS: for safer river use always verify the current official conditions before setting off; non-tidal conditions are provided by the Environment Agency (the River Thames authority) and categorised as Red, Yellow or Green – tap to view an explanation of the colours. Tidal conditions are provided by the Port of London Authority. Requires an Internet connection. Includes current and planned river closures and river restrictions.

IN CASE OF EMERGENCY: River Thames Guide includes an SOS section with information, endorsed by the RNLI, on how to deal with various problems including: Man Overboard; Boat Sinking; Boat on Fire; Boat Drifting. NOTE: these sections should be studied before embarking so that you can react properly to any emergency. Better still: take an appropriate course before using the river.

### 3/5 — Journey planner doesn’t work

*2019-09-25*

On the River Thames journey planner, you can select the star position but won’t let you select a destination unless you close and reopen the app

**Developer response:** This resulted from the Environment Agency RSS feed going off-line - now working again

### 1/5 — Map will not fully load

*2018-07-31*

When I call up the map it will only partly load on my (latest) iPad Pro. I have tried in various places at many times including at home with high speed broadband, also on the Thames using phone data. It is just not useable. Maybe needs an iOS update? Can you guys fix this please.

**Developer response:** Temporary fix is to tap ‘Home’ then tap ‘Map’ and it will load correctly

### 5/5 — The River THAMES App

*2016-03-26*

Very good informative App would help if you could forward the App to friends from within the App via tweeter / e-mail. Also when viewing an area with a Apple iPad it would help to be able to zoom in and view the area without it reverting back to the large map when you take off your two fingers off the screen.
Very good App keep up the good work

**Developer response:** Thanks - will look at adding the option to 'send to friends'

### 1/5 — Please don't remove detailed views

*2015-01-18*

Won't be taking the latest update that removes detailed zoom views. These are the most useful!
Otherwise would rate 4-5.

**Developer response:** Long since fixed...

### 5/5 — An invaluable boaters guide.

*2014-07-08*

Excellent App for both novice and experienced boaters. Comprehensive information makes this App a "must have" on board! Having most of the information available without the need for internet connection is also a major plus.

### 5/5 — Mr

*2014-06-12*

Excellent app in all respects , very useful for planning purposes .

### 5/5 — Fantastic

*2014-03-03*

A great, very handy app, I look forward to using it this summer. It would be handy to add a guide to public slipways and the tidal Thames too. Top app though, keep up the good work.

### 1/5 — Glorified Advert

*2013-08-13*

Seems like a glorified advert for Val Wyatt !!! Interactive map is fun but not really useful in any serious application. A decent waterways guide is still far far better. Generally disappointing.

### 1/5 — wont download

*2013-08-07*

It won't download………...

### 5/5 — Really useful app

*2013-05-17, version 1.3.5*

Great App, gives good information for using the river and for finding a boat
