For a good sleep. I look at a good anchor as insurance. [...] I just hope they don't anchor upwind of me. When people laugh at how big your anchor is compared to theirs I think you're on the right track. [...]
[...] This comes from having spent thousands of nights on the hook at this point and having dealt with many different situations. Knowing that your anchor is overkill will let you sleep even when there are thunderstorms or wind forecast(maybe a bit more lightly then).
I see an anchor as an insurance policy.
I like these comments a lot. I think there is too much talk in anchoring about what is convenient and easy to use, etc. That does figure into it, the anchor isn't any good if you can't break it free from the bottom and get it back on the boat, but shouldn't our first priority be making sure we don't end up on the beach ?
I don't have much experience compared to most of you guys, but I won't let that influence me when I am choosing ground tackle. I want super heavy, lots of anchors, lots of rode, lots of options. The anchors in my estimation are one of the most important things on the boat and I'd go without a radio before I'd go without heavy anchors.
I see no reason not to go with the largest anchor you can handle every single time you anchor. The only justification someone could have for not using the largest anchor they could deploy and retrieve is convenience. For me that means 80+lbs with chain, and I don't care if its a 40 foot boat or a 25 foot boat so long as I can set it.
If I was in an anchorage and I watched someone drop a 100+lb anchor off the bow of their 30 footer, I wouldn't laugh, I'd just smile and think to myself that they've been there done that, and got the anchor to prove it.
You can have too much sail, you can have too much keel, too much hull, etc, but can you ever really have too much anchor ? At some point it becomes a weight issue, sure, you wouldn't put an 80lb anchor on your sailing dinghy, but it seems like above about 20 feet in length you are reaching the point where whatever a human being (and windlass) can deploy and retrieve is best, just my opinion.
