Learnt alot about the river rising and how I should plan for this is the future.

River now dropping. Water weed, getting a extention strop and getting sorted early for next time

Any tips appreciated.


That is a lot of water Dean. I don't know what the Clarence is like but up here (Fitzroy River, Rockhampton), the speed of the water increases as the flood depth increases and it can get insane. I imagine you would have to cope with a very fast run which makes weed and logs more of a menace than with slow runs.

The last two floods when I had Windchaser, I trialled a new idea which worked for me. The problem I found when trying to move Windchaser off the mooring when the flood was rising was the pressure against the boat making it hard for me to slip the loop off the mooring cleat. If I had a deckhand, I could have had the boat motoring forward against the flow to take the pressure off, but always by myself. If too much pressure and me not strong enough to budge the loop, I would simply cut the mooring rope, but this was not ideal even though I had a sacrificial end on it so no problems about cutting it.

I tied a 5 foot 12 mm rope about 5 foot down from the loop on the 20 mm mooring rope loop. Just used a double clove hitch. To moor up, I would take the tension on the 12 mm rope and wrap it on the cleat. I tied up the thin rope such that the main loop in the 20 mm rope could sit loosely over the cleat. Thin rope taking the pressure, the loop end of the thick rope slack. If I was feeling paranoid, I would put a whip of thin cord around the main loop holding it down on the cleat.

Here's how it worked. The thinner rope did not slide on the main mooring rope not did it reduce the strength of the main mooring rope. The thin rope took all the pressure off the loop of the main mooring line. It was thinner and if it had broken, the main line was still over the cleat so would have taken up the pressure. When I wanted to drop the mooring, the main mooring rope loop was loose on the cleat, no pressure on it as it was taken up by the thin rope, so lifted easily off. Then, since the thin rope was only wrapped on the cleat, it could be unwound no matter what the pressure, or could be cut as it was totally sacrificial.

While putting the two ropes on the cleat was a bit fiddly, I found it worked. Quick release is less stressful than trying to saw through a rope with the panic of a flood. You can understand why nobody ever uses chain from cleat to the mooring. If chain is jammed on a cleat, bit hard to cut and release.

Thanks Louis

I was trying to work out how to create the bow cleat untensioner, that sounds the go to unload the huge load for 3t vs 12kn+ current.

Any suggestions for mooring extention strop. Thinking 10-15m of same diameter as mooring strop, (learn to) splice an eye at each end and loop thru mooring strop.

Splicing rope is great fun. I found the animated knots website excellent. Took me a while to get it, but then I am slow. Once I could do an eye splice, I discovered if I left it too long before doing one out on the boat, I would not get the start right. So, I either took my ropes home to splice them while checking with the animated website or practiced the start before going out to the boat. :oops:

Oh, I found it best to practice on new rope. I first just grabbed a small piece of old stuff and thought it must be impossible to splice. Nope. The old rope had just hardened up past the point I could splice it.

Have fun.

Think I've fixed it.

Took the lifelines off, one of the supports, on one of the stauchion bases has come away at the weld, thought i might as well remove them all, over drill the holes, fill with epoxy, redrill and reinstall and seal withbutyl tape.
