Back in October, my friend Chris and I went for a long day sail in Spiders, my 16ft Wayfarer dinghy. We decided to take advantage of a rare combination of Westerly offshore breeze and ideally-timed tides (High Tide was at noon) and head for Burnham on Crouch.

We left Brightlingsea at 0815, quickly putting in a reef to better handle the 18knots gusts as we reached down the River Colne and across the mouth of the River Blackwater. The spring tide was barrelling in at over 2 knots, and as we crossed the main Blackwater channel the wind against tide bumpiness was slightly testing, but nothing too scary.

The sea state calmed once we’d crossed over onto the Dengie flats, and we were averaging almost 7 knots as we passed the 7th century St Peter on the Wall chapel and headed towards the Ray Sands channel on the rising tide. This is a short-cut across the mud flats and into the River Crouch. It had very nearly caught me out back in 2008, when my route planning was less careful.

There’s a very useful informal chartlet of the Ray Sands channel available on the Crossing The Thames website. It’s from surveys done in Aug/Sept 2022. We crossed the shallowest part of the Ray Sands channel at 1000, with plenty of water to spare so we went straight from Ray Sands Middle buoy to Crouch No.3 buoy, which avoids the dogleg via the yellow Ray Sands buoy.

However the wind against tide conditions as we tacked into the mouth of the River Crouch were bumpy and wet, and we hove-to to put on another layer and have some chocolate. Luckily the sea state eased a little as the we passed the entrance to the River Roach, and the final beat towards Burnham was enlivened by having to avoid trashing the start of the first Endeavour Trophy race, which is the champion-of-champions for UK dinghy racing.

We moored up at the Rice and Cole jetty at 1115, and had a welcome Cornish pasty for lunch in the bar of the Royal Corinthians Yacht Club. We returned to the Wayfarer at midday, just in time for the tide to turn, and the sea state to dramatically flatten as a consequence. The gusts had also lessened, and so we raised full sail and enjoyed an easy run back down the Crouch (video). We then turned up across the Ray Sands channel again for a close reach across the Dengie flats (video). Conditions were ideal, with a nice F3 from WNW, so Chris had a go at helming, without incident.

It took us a while to plug the outgoing tide across the Blackwater, until we finally spotted the beacon marking the wreck of the Molliette which for me marks the start of the River Colne. We hugged the shallows of the Mersea Flats to escape the ebb tide as we made our way back to Brightlingsea, sailing onto our mooring at 1530.

32 Nautical Miles sailed, at an average of 4.8knots. Our only big mistake was thinking it was too late in the season to need sun cream. That’s a good day on the water.

Sometime tomorrow morning Yvan Bourgnon will sail into Ouistreham Riva-Bella after a 30,000 mile / 220 day circumnavigation in a 6m open catamaran.

That’s “open” as in “has no shelter”. It’s like a big Hobie beach catamaran.

Here’s a video he took as he crossed the Pacific.

Yves, you crazy. I salute you.

GPS tracks after 3 years sailing the River Blackwater.

I bought Wanderer 446 (a 14 foot sailing dinghy) nearly three years ago.

She’s given me much joy as we’ve explored the River Blackwater in Essex.

We do day trips, each destination determined by state of tide, wind and mind. The picture above shows desire paths of moon, mood and meteo.

“You get to this nowhere land where your brain is utterly disconnected, and I think…I think that [is at] the root of all this… obsession. It’s trying to get into that little slot of your brain where things don’t exist and yet they’re working perfectly. It’s a sort of heaven. A nirvana.” – Alexander Waugh

Sailing home to Bradwell…

I enjoy cruising my sailing dinghy around the rivers and coastline of Essex and Suffolk, and have recently discovered a feature in Google Earth which makes planning trips that little bit easier.

Google Earth now has a ‘historial images’ tool, which on my mac is in the form of a clockface-meets-arrow icon, and brings up a tool looking like this:

Moving the slider lets you change the date of satellite images.

Somewhat wonderfully for sailors on the River Blackwater, and seemingly also for most of Essex and Suffolk, a couple of the recent series of images seem to have been taken at spring tides, both high and low.

For shallow draught dinghy cruisers, happy to dice with a mudbank or two, this lets you now plan new routes thanks to the offer of accuracy with which a nautical chart can’t compete.

For example, to the south west of Bradwell Waterside, on the River Blackwater in Essex, there is a large mudflat, through which flows a narrow and winding channel known as St Lawrence Creek.

At anything other than high or low tide, this route is a bit iffy, since it’s hard to know when you’re in the channel when the whole mudflat covers with water, albeit not to a depth to let you sail safely.

This is a shame, as it’s a nice shortcut home to my base at Bradwell Waterside, where I keep my 14 foot Wanderer sailing dinghy.

Here’s the Navionics chart of the St Lawrence creek:

(Check out the new, free Navionics chart web app – it’s great, as are the Navionics smartphone apps)

Now, here’s the same area at spring low tide from Google Earth, complete with a series of waypoints which I then use on my GPS to let me follow the channel whatever the state of the tide.

Following this route carefully means I don’t have to worry about my rudder hitting the bottom were I to stray onto barely-covered mudbanks at mid-tide.

To be fair, there’s no need to follow this route at or near high tide, shown below, as there’s enough water everywhere. But at mid tide, it’s a reassurance that you won’t hit the bottom.

I’ve tested the route a couple of times mid-tide, and am happy to share waypoints if anyone’s interested (YMMV, mud shifts etc).
