Thanks, Charles, for repeating what I stated in this thread from my very first
post. I have read much of but not the entire thread (life to live...), but the other putative benefit of a buoy in the rode is that the bow of the boat won't be subjected to such violent forces as it pitches up and down in waves. The rode as attached to the boat is closer to horizontal, so doesn't jerk the boat down so hard on every rising wave as when the rode as attached to the boat is more vertical. So I've read!! ==== Charles T. Low www.boatdocking.com ==== "Steve Smith" wrote in message . com... Hi all ... surprised to see recommended that a mooring-type buoy be used rather than attaching some other flotation to the intact anchor chain (one more link to go wrong). |

In other words, you can't figure out the difference between nylon and polypropylene.

So you're still insisting the 3-strand nylon is destroyed by stretching 4%? Why do
you suppose NE Ropes describes it as having "high elongation" and has a chart showing "working elongation" of over 20%? Don't be such a coward jaxie. Be a man and just admit you made a mistake.

Hi all
Thanks for all your contributions. In the UK there is very little information that I have found on using either of these methods apart from the occasional mention of using short snubbers to reduce shock loading when using chain and the lowering of weights etc. to give a more horizontal lead and to provide some damping when using rope and perhaps chain. Mixed chain and rope is probably used as much here as in the US with appropriate chafe prevention. My own experience has been generally with all chain with no problems but I have not experienced anything like the weather that you get in the US. I am planning on a circumnavigation and will have all chain for most use since I think the benefits do outweigh the detractions but I appreciate that in severe conditions the shock loading aspect and pitching of the bow could be the decisive factor so would look to other alternatives. I would have an equivalent length of chain/nylon for secondary use and probably additional rodes. The benefits of the buoy method seem to be - sufficient damping if the buoy is large enough and lessening the pitching of the bow. As was rightly pointed out this can only occur if the chain is not pulled bar tight by the constant force from the wind. The problems that I see with the rope and chafe protection is that it has to be maintained and in severe conditions when a crew is likely to be exhausted this may not be possible. Any method that needs less maintainance is then more attractive which is why I was interested in the buoy method. Apart from hearing of quotes in Hinz's books (I haven't managed to persuade the library to get a book after two attempts) I have only come across it mentioned in Hal Roth's 'After 50,000 Miles', an excellent book although quite old. If anyone can scan any of the relevant information from Hinz's 'Complete book of Anchoring and Mooring' I would appreciate it. Apart from fishing boats using this method there seems little other evidence of its use. Thank you again for all your comments. Regards Steve Reemove defcv etc. (Steve Smith) wrote in message . com... Hi all Having looked at Chapman's 'Piloting, Seamanship and Small Boat Handling' (now available in your local library for UK readers), I was a bit surprised to see recommended that a mooring-type buoy be used rather than attaching some other flotation to the intact anchor chain (one more link to go wrong). I think Hinz discusses this in his books but I haven't managed to get hold of any in the UK. I know this method of anchoring is for extreme conditions but has anyone any experience with it or the alternative method of using weights slid down the rode. I would guess there is a better argument for avoiding shock loading than there is for anchor dragging and that the buoy method is better at doing this. I am assuming all chain here due to chafe resistance. Regards Steve Remove defcv if etc. |

The problems that I see with the rope and chafe protection is that it
has to be maintained and in severe conditions when a crew is likely to be exhausted this may not be possible. I have said it before and will say it again and again and again until people listen. chafe protection on nylon is NOT wrapping a t-shirt around the line and hoping for the best. Proper chafe protection on nylon is at least one, better yet two, "safety" line rolling hitching onto the nylon rode. the first safety line takes 100% of the load until and unless it breaks and then the second safety line takes 100% of the load until and unless it breaks at which time the nylon rode takes over. IN ADThe problems that I see with the rope and chafe protection is that it has to be maintained and in severe conditions when a crew is likely to be exhausted this may not be possible. IN ADDITION, *proper* safety lines are wormed (if three strand, not necessary with braided line, which is better because is stretchs less back and forth going through the chocks), parceled and served with Spectra fishing line. This makes for one serious hard spot in the safety line where it goes through the chock/edge/whatever. If you want belts-and-suspenders, you can also use firehose over the hard spot, and even plastic tubing over the firehose and even a t-shirt over the tubing if you want. worming/parceling/serving has worked and worked well for centuries. It felt out of favor of recreational sailors of late because it requires a sailor to spend some time properly preparing a safety line ahead of time and most recreational sailors are rather lazy, preferring early sundowners instead. an all chain rode *will* pull your anchor loose (or break of the deck mount) in a blow. Dragging anchor on all chain in a blow is NOT an act of god, but rather an act of negligence on the part of the sailor. |
