I ended up high & dry trying to run a 30 mile shortcut thru mangroves called the Narrows at the back of Curtis Island in Qld OZ. Depths thru there fluctuate between 4 and 6 ft even at high tide. Unfortunately I became stranded at the "Cattle Crossing" (that's why they used it, I guess) which is the shallowest part of the whole shortcut which can dry 6 ft at low tide. The bummer is you can see deepwater only a few hundred yards ahead.
So we sat down & dried out - no big deal you would think. I put the anchor
out, emptied most of the water
& moved the spare fuel
drums to the RIB
in preparation for refloating when the wet stuff returned. I did not have any bow babes to unload & the beer
was all drunk. I took the opportunity to explore the remainder of the channel & discovered there was some nasty pointy metal things poking out in some places & marvelled at the furrows ploughed by boats that had bulldozed through in the past.
UNFORTUNATELY I did not take into account the 15 - 20 kts of wind
that was blowing against the side of the boat. As the water
returned, the boat agonisingly scraped & bounced across the gravel of the bottom and attempted to wedge us into a high mud bank with tree roots protruding opposite us. The result was a cracked dagger board case as they still protruded a little way even when you had attempted to pull them up all the way.
We were saved from being blown up onto the mudbank & skewered by the roots by winchinh off using our anchor
that I had laid out earlier.
I had forgotten to take into account the effect of windage on the hulls from the strong wind
. The returning tide was not going to be the only force acting on the boat when it refloated.
LESSON LEARNT = if / when it happens again & there is wind blowing, I will secure the boat laterally fore & aft to the mangrove trees with looped lines, for easy retrieval (HOPEFULLY) when boat refloats. If the wind is coming from behind then ropes to both banks astern would be the go.
PS You don't want to be wading around in the water in a mangrove swamp in Australia's north. You may end up as a tiger shark or saltwater croc munchie.
You live & hopefully learn by your mistakes
