Would anchors even het used on this type of boat or for that matter most commercial ships today
I think they just go from pier to pier and are roped onto the big doohikies that look like half a knuckle bone sticking up on the jetty
Ships often have to anchor, awaiting a berth in port. Port Hedland is a perfect example.
I did not know that V8Ian, I guess now that I think about it Im pretty sure even for little boats there is moring fees and I can only imagine big ships would have same bills as well only a lot lot bigger
So once they are empty they would head out to open ocean and pull up and wait
So yes it was a dumb question from me
Dave you are probably right
I know nothing about boats except they make me crook
Your better to die trying than live on your knees begging
They used to use bigger chain than that for scrub pulling in central Qld back in the day..............by the way ,the strutted chain is so if the links pull out of shape ,the struts prevent the chain locking solid in a long length.

From all the Tractor sites it seems that two late model D9's use 2 1/2 inch to maximum 4 inch chain. About 3 inch is average.
Two late D6 use 1/1/2 to 2 1/2 inch.
This assumes the operators have a veritable library of chains to choose from which is seldom the case. Too heavy and it stays low - OK for light stuff but on heavy timber requires a chaser dozer with a tree pusher to knock down stubborn trees that catch the chain (said to be the world's worst job having to bounce over the fallen scrub and expected to be everywhere instantly to keep the pullers moving). Light chain rides up and snaps trees off higher up instead of the desired lay down effect..

Hi Lang and Paul how are you? I pulled quite a few acres in central Qld in my youth d8h22a s stick and D9G s powershift never heard of chaser tractors we leaned the big trees so the chain would run up it might be a bunch of big trees chain might go 15 feet up then it would pull them all over if a big tree was on the outside you just pushed it out into the pulled scrub. Never pushed them over inside they would get tangled in the chain end up dragging heaps of timber along . If you got hung up on a tree you backed up the chain abit more than length of the tractor and you could turn around walk back and lean it or back out over the chain back all the way back to lean it so long as you had the slack under the tractor you could do anything with out hurt the walking gear . Other ways they got the chain higher was the big steel ball in the middle of the chain lifted it by 5 foot to give purchase and if more bight was need one tractor would sop causing the ball to pull down and lift the chain higher on other side when it hit the tree stopped tractor would go and chain would tighten up high on tree . There is one of these ball on the peak downs highway at a stations gate. Another way was to run a 2 inch wire rope attached to the chain about 80 feet back from tractors and 20 foot shorter than the loop of chain being lighter it would run about 15 feet in the air give purchase on the trees leaning them than the chain pulled them over . Chain was about 2 1/2 inch but it would break now and then carried bud dees on the tractors to join it again

That info I got came from both USA and Australian forums. No doubt every case is different as there seems to be unlimited combinations of tractor size, chain size, type of vegetation etc. I have been on properties where they are clearing quite a few times and you confirmed my impression it is more than just blindly charging through the scrub knocking everything down with ease.
Thanks for your insight - always thinking. I suppose it is like most dozer jobs, even if there was such a thing as a 200 ton D99 it would still be one size too small for the job in hand on many occasions.
