'morning all I've been up reading about anchors on the other side... Clarity is NOT something I've come away with as every thread seemed to turn into an argument lol. Hey ho. The only CLEAR thing appeared to be that it's a matter of compromise. SO - give we are based on the Aire and Calder navigation, I accept we do need to have some kind of working anchor on board... but like everyone else, space at the bow is limited. 2 options seem prefferable: a 14kg danforth on 3 metres of chaine or 15 kg folding thingy... on the same chain. I accept a bigger, heavier one would be more ideal - but surely something has to be better than nothing and having walked along the tow-path where we are, I've not seen many bigger ones (unless hanging from the bow of the humber barge's. Annoyingly, a while back I had ordered a 20kg one which never arrived and limekiln only have the above 2 and since they refunded some postage last week, I want to buy from them. Thoughts appreciated. oh - I nearly forgot my question. ROPE wise, I can't work out the "force" that might be on the boat but wonder if something like 12mm would be thick enough?

Well, a horse can pull about 330 pounds so that would be a good ball-park figure.
"James Watt determined that one horse could exert 330 pounds of force in moving a load 100 feet in one minute."

I would suggest that you need to think weight that you can easily lift and put over the side and the weight that you can easily recover. I suspect the latter will be a 10kg anchor plus its chain and warp.
An anchor is no good unless it can be easily launched and recovered. Unless an anchor bits into the bed of the water it would require much more that 14kg to hold your boat on a dragging anchor.
Mine is is 10 kg plus about 10kg of chain plus the warp. The chain and warp are stored in a box in the well deck, used as a seat, and the anchor goes under the well deck thwart on its side.

with the choice as given I would plump for the Danforth and 12mm rope (that is not too bad a thickness for handling ..... remember you usually prefer to get it back!)
(12mm synthetic ropes will have a breaking strain of between 4 and 6 tons depending on particular type if you need stronger than that you are probably fucked anyway)

cheers fellas - that reads reassuringly ... I'll get it ordered - the boat's first journey when taken off the lorry includes about 5-6 hours chuggging on the River Aire then calder so I want to make sure it's all shackled up BEFORE we leave Selby.

If you are making up your own mooring warp and are a little unsure then this might help. it is one of the clearest descriptions of splicing to chain that I know about www.samsonrope.com/Documents/Splice%20Instructions/3Strand_C1_Rope%20to%20Chain_AUG2012_WEB.pdf

I read that the anchor size goes of the size/weight of the boat etc, aswell as amount of chain, more the better to get dug in quicker. What boat are you wanting to anchor. Sorry if i have missed it.
On my 20 foot cruise ri will be having a 7.5-10kg anchor ( Bruce type though, but not in your choice, I would get the Danforth) and 10m of 7mm chain with 12mm rope.

I ended up with a 15kg danforth with about 10 kg of 8mm chain and a 12 mm rope - the rope ISN'T really long enough (chain is circa 10ft and rope is about 40)... it's better than nothing and I hope I dont have to deploy when going downstream... I WILL improve it .

We have a 25kg danforth on our boat, purchased many years ago to go up the R.Severn. Luckily have never had to use it in anger. I think it has 10ft of chain, with some rope on the end. I always used to carry it at the stern in case rapid deployment was required , with worst case scenario of not recovering it at all, but at least it may have stop us going over a weir.

remember as well that the standard figures are to hold a sea going boat in severe weather with high winds and rough seas.
