That's debatable. As someone once said There is nothing, absolute nothing, half so much worth doing as just fucking about in boats on the Thames while you have enough money and health to do so. Or something like that

Dulcinea really is a great looking boat, you're a lucky bugger

It's a lovely vessel. I've had a few comments about it. Well actually more than a few The most upsetting ones were people saying I could put a cabin on the back deck for more space. That would be criminal! Maybe this boat was lucky to end up with me as none of that sort of nonsense will happen under my watch. I know a sorted boat when I see one It's just been "sorted" down to the minute details. Bit tricky to keep it going in a straight line while using phone to post on forum though Chain rod and crank steering innit

I was never sure if it was arguing about different types of anchor as both parties were very insistent. Does it change with different anchors ? Rog not really.
a good length of chain attached to the anchor curves downwards in an arc from the boat (or the rope that extends it to the boat) this does two things.
.Because of the curve it acts like a spring so that if the boat "snatches" at it the shock is not transmitted directly to the anchor.
Also because of the curve the pull on the anchor is along the bed of the river driving the flukes in deeper rather than upwards and off the bottom as it would be if it was just rope tied to it.
I was anchored off Spurn Point in Sabina in a force 7 which combined with the very strong tides meant that my anchoring equipment got a good test. the plough anchor on about 60 metres of chain had driven itself so deeply into the bottom I had to use the engine and go over the top and pull it from the wrong side to help free it. there was a good 20 foot of the chain was caked in clay where it had been driven in.
Thank you ... I think I understand the two arguments now. In deep or moving water, as you describe the boat, rope, chain then anchor would be necessary and in any case, what most including myself, would expect. The alternative argument of boat, rope, anchor and then chain is actually using the anchor as a mudweight. Or have I got it wrong again JohnV ? Rog

Why have you got a toy trawler then? Because I always wanted one since I was 11 and the bloke kindly made it for me when I was 11. It's not a real trawler. Yes it could deal with force 9 or whatever if it came to it but it is also meant as an inland cruising vessel albeit fairly deep at 3ft4 or one metre draught. It has turned out to be the perfect Thames boat and as the Thames is the perfect river I am not moaning Culham lock awaits It is a lovely boat....

I know of no logical reason nor have I ever come across any boat in 60 years of "messing about in boats" that uses anchor. rope. chain.boat
if you want a mud weight far better to simply tie a mudweight to a bit of rope . (or simply drop the anchor so it barely touches the bottom and use that as a mud weight)
There is no reason you cannot use rope on its own but you need to let out several times the length compared with chain to get it to hold.
A disadvantage of (ordinary) rope if there is no strain on the anchor (change of tide, change of wind, w.h.y. ) the rope can float to the surface and be a hazard to propellers, both your own and other peoples.
I say ordinary rope because there is a special rope made for anchoring that is weighted and sinks, this avoids this and also gives a little of the shock absorbing effect of chain .... but if you are going to buy sufficient special expensive rope to make a complete anchor warp why not just buy a length of chain and extend it with ordinary rope (the chain will last many, many years of hard use and won't fray, is UV proof and won't degrade)
It's like many things, if there is an established traditional practice then there is usually a good reason for it

Thanks ... I'll stick to canals anyway ... you can always get out and bow haul to the bank rather than drop anchor Rog

Magnetman said he felt safe from me as he was on the Thames ... I jokingly said I need to 'acquire' a river boat like Dulcinea.
We'll continue to do the stretches of rivers necessary to link two canals ... but that's all.

Always worth making sure it is attached to the boat. I have had several anchors out with nothing attached. I think this is the best advice, well for me it is, I have a tendency to not think and do, causing loss, damage or pain usually.
