Distance from Anchor = Rhode Length

You're correct. I should have clarified that when we use that ratio we either specify how much chain at the hawse or at the water. So in the case of a sailboat it would be at the hawse or roller where you would measure. Thank you for that.

Re: Distance from Anchor = Rhode Length

Why don't you just make it easy and mark your chain in 30ft or 30 meter increments then let it out corresponding to fathoms x one or meters divide by two in relation to actual depth. Adding an extra 8ft at the beginning to account for freeboard + snubber slack?

Example, if the chart says you are in 2 fathoms... Let out the chain to the second mark. Or if the chart says 4 meters... Let it out to the second mark for five to one scope. Double the amount for 10:1. What could be easier?

We have our chain marked in yellow, red, green and blue. Just let it out to each mark corresponding to depth for 5:1 or double it to the next series of yellow, red... Marks for 10:1. No calculators or math problems involved.

Re: Distance from Anchor = Rhode Length

It is a long formula. Fine, but difficult to resolve in situ.

I use this:

- dist to anchor max = less than anchor rode length,
- dist to anchor min = anchor rode out minus depth,

Example:

We anchor and let out 100' of rode in 20' of water.

- max distance to anchor less than 100',
- min distance to anchor 80'.

Simplistic and some err on the max but can be easily resolved in any head.

Dude, do you always let your anchoring become this complicated?

How long does it take you to perform this type of mathematical gymnastics?

Re: Distance from Anchor = Rhode Length

Just reading through these posts again and in other areas of this forum, and I am surprised how often the pissing contest goes on and the attempt to sound smarter then someone else. How about instead of shooting down people's ideas or throwing out armchair theories to stroke your ego, we put all that aside and have constructive conversations. There are many ways to skin a cat. So throw your idea or advice out there but leave the negativity out of it. If someone chooses to use your method or advice so be it. If not, then at least you did something to actually try to help a fellow sailor regardless of their experience and leave it at that. Who knows, with a more open mind you might learn something new yourself.
That's my rant. Thanks.

Re: Distance from Anchor = Rhode Length

For all the folks diving on their anchor. Why don't you just bring a shovel with you and bury the anchor manually. You'd save all the drama of backing down and yada, yada, yada... I mean you're going down there anyway, right?

I will confess. I have never dove my anchor and I have never dragged. However, I am a realist and I know it is not a matter of if, it is a matter of when.

I have run aground already so that monkey is off my back, thank God!

The religion of anchoring is fascinating...
