I have just returned from a week's cruise that put this pilot to good use from the River Ore/Alde to Maldon on the Blackwater. The pilot was easy to use, concise but not to the point of being dry to read. I found the large colour chartlets excellent and accurate and I particularly liked the buoy-by-buoy notes and "roadmap" courses & direction arrows for harbour entry. The summary tables of key information for each harbour were useful references too.
Some criticism - I did feel that the preferred port/river entry times w.r.t. high and low water were a bit skimpy. For example, the prefered entry time for both the Ore and the Deben are just given as HW-2. In fact it's quite feasible to enter or leave at low water in a shoal draft boat. For the Ore its useful to know that the ebb continues to flow for about an hour after LW at the bar which gives a useful extra bit of depth if you leave at this time. This is not mentioned but entry/departure times are a matter of some concern to a skipper new to this coast and fuller information on what would be viable and safe times to arrive/depart from the more challenging rivers would help in passage planning.
In summary, this is an excellent and most welcome new pilot book from a respected publisher that I would expect to provide strong competition to the established "East Coast Rivers" pilot. It also has the benefit of a website giving updates. Users are invited to contribute.
Final note:- The copy supplied to me was soft, not hard, cover. Amazon lists it as hardcover, which would be better.
