Rope rode or all chain

>In the Baltic, the anchoring practices would make a British sailior faint. Scopes of 2:1 if that, and all rope rodes

>>In the Baltic, I think that's more due to the negligible tidal heights differences and currents.

With 2:1 scope all rope it can't just be lack of tides and currents it must be complete lack of wind also ;-) or they don't know what they are doing. In fact I find it difficult to believe because they would drag most, if not all, of the time.

> If I can carry 40m of it on my 24 footer, you big boat chaps ought to be able to manage the same or better.

Not such a big boat ours is 38 feet and we carry 60 metres of chain for the main anchor, plus 2 x 30 metres for two other anchors.

It is lack of wind as well, and the thick mud which never fails to set your anchor. Never seen anyone drag there, although I have seen many bump in the night when they all randomly float around in the calm anchored 3 feet from each other.

It was the practice of all rope road that enabled a Swedish inventor to develop the "flying anchor".

In practice a yacht would moor up to an island bows first. Then he would launch his "flying anchor" from the stern. Based on a danforth type it was supposed to fly out using hydrodynamics to at least 30 meters from the stern of the yacht. If I remember correctly it even had wing tip spoilers just like an Airbus.

I saw videos of the demo at the boat show but never saw one used in real time anchoring.

Regarding my M346 question. I have now loaded 50 meters in the anchor locker but the top of the pile is close to the hawse pipe so I guess I will have to spill the chain regularly when it gets beyond 30 metres.

90m of 10mm chain but then I only have a CQR on the end of it

If you have a CQR then you need neither chain nor rope!

BlueTwo,

The chain locker on the M346 may seem small but I suggest it will hold far more than 25m of 8mm chain. The main problem is preventing a pyramid forming when recovering the anchor. I have approximately 25m of 8mm chain and my locker (M346) is less than half full.

I have never needed more chain or added rope but then I anchor only in shallow water. But I do have rope to add if ever the need arises.

It really depends where you anchor and in what conditions that determines your need.

Lots of M346 owners on the Moody Owners Association website for further advise.

So how does 25m in total work? Allowing for cleat to waterline it is down to about 22m - so at best 3:1 in a depth of 7m, and 5:1 in a depth of 4m.
How does that work with Bristol tides of 10m or so ?

Further to the OP's question, then how do you attach your rode to the boat. I assume if you are using all chain you use a shackle.Any reference books I have seen imply that the shackle for chain has to be high up in the chain locker not at the bottom.

The standard answer is a length of line, partly so that you can cut it if you need to dump the chain in an emergency (although more relevant to below-decks anchor lockers as you *could* unshackle the chain in the modern deck locker) and partly as a shock absorber in case you somehow have the chain run out in deep water. With a plain shackle the jolt as it comes up short will put a massive load on whatever it's shackled to, and boats have been sunk where the attachment point was a ring-nut on a bolt holding the stem together.

Any reference books I have seen imply that the shackle for chain has to be high up in the chain locker not at the bottom.

That's certainly the case for ships' anchor lockers. Obviously a pile of chain on top of the shackle will prevent you accessing it. Although I'm not sure why you'd need to regularly on a yacht, and I wouldn't count it as a high priority.

Interesting but daft. We met many Scando yachts in the Caribbean and they all anchored properly.
