Returning from a hot bridge cunningly named The Severn Bridge (I think)

Cunningly named mud FLAT was chosen to play/ practice touch and goes, goes around, comes around.
Can i draw the readers attention to my approach slide which displays a pleasant carved muddle groove from my still erect divider and bow curtain!
What a joy to behold.
Its easy on cruises to
Start
Cruise
Stop.
This mud flat away from all twitchers and houses allows us to practice. Repeating the same manouvre allows skills to be honed. Staying above hump whilst turning to return to land with various wind and wave levels all helps to build skills. Gentle curves on mud can only occur if attention is paid to the lift levels and mud / sand quality, to avoid tuck in due to low lift or mud stickiness

Been very busy with the house since we moved in - the list of jobs is never ending - but found time for a Christmas Cruise. I couldn't really go boxing day, depite the good weather, as the tides have been pretty big bringing a 2* bore over the holiday. By today it was down to 8.2 m and the weather was good so off I went.
 
The plan was a trip down to Welhouse Bay opposite Sharpness for no other reason than its a good destination for a joy ride, and that was exactly what happened!

The weather was cold but calm under a leaden sky which slowly brightened up through the afternoon, so I got some nice pictures to share. There's something about the Severn, it always looks bluer and warmer in the photos!

Conditions were pretty good on the way back!


But it was a bit choppy in places where the tide is running over the submerged sandbars


Back home into the late afternoon sun

Looks well chilli!!!
Sorry couldn't get down for various - :-[


"soon" is the cry!


Was bought this from the Hover museum guys,
so trying to make room to read.
Shame there are FEW small craft, although
they DO get a mention- its only that.

My neighbour was keen on a little run down the river and the  weather was good so I was keen to oblige!

Three rules:

If something changes with your hovercraft, find out why
Don't turn off your engine if you're in an exposed position
Only stop somewhere you can walk out of

Two broken!

Turn key : nothing. Sh*te!

Should have investigated why it was turning over slowly when I started. With tide coming in, the only saving grace was that I chose to stop on the bank rather than an isolated sand bar and the light failing.

It was about a 30 minute walk to the road, but I wouldn't be able to leave the craft until high tide about 7:00 so that will be in the dark :( so thats plan B. At least I did have a plan B - If I'd been on the sandbar it would have been mayday, much bigger craft get rolled over by the flood tide on these sandbars.

Plan A is fix it. Break out the tools, soon found the dead solenoid. I carry a spare but given the gathering darkness a spanner, some big blue flashes and loud cursing had it running again.

Phew! New solenoid in the morning.

Those loud blue flashes are most unnerving, as you "feel" its YOU being electrocuted, and NOT the spark to earth---
Ive cut myself whilst withdrawing my hand VERY fast in the past!  :-[

Finally fixed it.  I put a new solenoid in, only to find the symptoms unchanged. Doubting my original diagnosis, I methodically went through the whole system with my meter, on to arrive back at the same diagnosis - defective solenoid. Which is of course brand new. Removing it from the circuit confirmed an open circuit coil 😥 Still, found another solenoid and it's all good now.

Also cranking much more energetically - this issue has been developing for some while. Ordered a replacement for the spare (carried on the craft) which I will bench test when it arrives!

Little trip out today - in deference to the huge tides this weekend, upstream rather than downstream. In truth upstream is a bit dull really once you've done it a few times but it suited me to go out and given that a huge bore was expected in the evening it gave me a chance of recovery should I have a breakdown. Breaking down in  the lower Severn on such a tide would mean the loss of the craft almost without doubt. Not to mention the chance of a little helicopter ride!

The bridges at Gloucester and Maisemore were a bit touch and go - I got under them (slowly!) but there was not much to spare with the amount of water coming down the river from Wales. Makes for a good bore though!

Well it's been 4 years that I've been solo cruising from monster worth, it had to happen eventually. I took the craft out for a short cruise after work, started it going a few miles up river then came back. Passing my place I headed off down river bound for Garden Cliff or Hock Cliff. Didn't get too far before the engine went down to one cylinder then cut out. This was 6ish with the tide due at 7:50 so no time to faff really, engage Plan B without further ado!

Plan B consists of a tiny Chinese outboard, this was deployed to bring me to a suitable spot on the bank to tie up and to get out to the road. It really doesn't have the puff to oppose the current, but there's a world of difference between in the stream and on the bank (especially if it's the right side!). Once the craft was tied up I had about a 2 mile walk back to my place to collect the "tug", a 14ft Dory with an ancient 40 horse mariner on it.

The boat was soon in the river, and in fine 2 stroke style started first pull (really!) But I won't mention that it stopped after a few seconds then was a right bugger to restart :-\ but start it did so we were good.

Taking the craft into tow was no faff at all, although steering was "interesting" as we made a drunken return journey at a decent walking pace.  And then the beer. Still, the boat has now earned its space on the bank!

"Oooooh the SOUND of silence"
With Simon AND Garfunkel wailing away in the background, I'm sure we all commiserate, as flash backs (or is it "flashes back") crowd in on ones memory bank. Yuk (apart from the the well earned beer on the bank) swiftly followed by all the WHYs?
Not however "WHY am I doing this?"---- oooh no- just the cause (s) and prevention/mitigations necessary to avoid repeats.
I hope the severn banks (WHY so many??????! ;) ) ECHOED to that good old Yorkshire BELLOWED expression---------

Looked at it today -no water in it.  It was ok (at least there was water in the header tank) before I set off. Must be a leak somewhere though. The engine was pretty hot when it stopped, but seems ok now that theres water in it. It has a temperature sensor and is programmed to shut down at about 115C if I remember correctly.

I suspected a water leak yesterday when it happened, and thought it was probably a big one but no obvious sign of it today. More investigation needed, but at least the engine protected itself and survived the ordeal. Hurray for modern electrics!

It is possible to have water in the header/expansion tank and none (or little) in the engine/radiator - assuming it's a unpressurised expansion tank?  It takes a few hot/cold cycles to equalise the water volume in the system.  In theory, air (and coolant) is pushed from the radiator into the expansion vessel as the engine heats up - when it cools, the water is sucked back into the radiator through the cap (it has a one-way valve to allow this - as well as the "normal" pressure valve in the other direction.

Might be worth checking for a drip from the water pump leakage hole?

Any sign of water in the oil?
