A cruising Skipper needs books, charts and tidal information ready to hand in the cockpit or wheelhouse. A useful selection relevant to the River Severn and Bristol Channel is given below.

'Nicholson's Ordnance Survey Guide to the Waterways'  is a definitive source of maps and information for the river and canal system. Volume 2 includes the inland River Severn and Sharpness Canal.

The 'Lundy & Irish Sea Pilot'  by David Taylor (published by Imray Laurie Norie and Wilson) is a useful guide to the Bristol Channel covering the ports in England and Wales.

A wealth of local navigational knowledge is contained in the 'Blue Book'  published by the Bristol Channel Yachting Association and on the web sites (see Bristol Channel ) of local yacht clubs.

The 'Bristol Channel & Severn Pilot'  by P Cumberlidge (published by Stanford Maritime ) is a classic guide to the Bristol Channel.

The standard marine charts for the United Kingdom are produced by the Hydrographic Office for the Admiralty.

For passage planning, the Small Craft Series is recommended with Chart 1179 being relevant to the Bristol Channel.  This should be supplemented by other larger scale charts for the areas in which you intend to cruise.

Chart 1179 does not cover the estuary and river above Avonmouth and for this tricky area Chart 1166 (Avonmouth to Sharpness) should be regarded as essential.

Do not forget to update your charts with information available in 'Notices to Mariners'. These are often summarised in the monthly boating magazines or can be obtained online (see below).

With the second highest tidal range in the world, daily tidal information is essential for safe passage in the River Severn, Estuary and Bristol Channel.  Tidal currents may be strong and many ports are only accessible around high tide.

On a daily basis, tide times can be obtained from a variety of sources including newspapers but for extended cruises a Nautical Almanac or book of tide tables is essential. Local tide tables can often be obtained from coastal bookshops or fishing tackle suppliers.

Some useful conversions and boating formulas are given here.
