Storm Anchor

[JebLostInSpace]

So I'm working on potential hurricane plans in Charleston, SC. Some of you may have read about that already in this thread:

It looks like plans A through D are going to involve anchoring the boat up one of the rivers here, and leaving for a few nights while the storm goes through. I got lots of good advice on that previous thread, and I think this is going to be the smart move for my situation. To that end, I've decided to get a more serious storm anchor ordered, in the hopes of worrying a little less when/if the time comes to leave the boat for a big storm.

I'm pretty sure that I want to get a Spade Anchor. I follow S/V Panope's testing videos, and the Spades performed really well in his usual tests, as well as his veer tests where he backs down hard while slowly rotating the direction of pull by 180 deg. That seems like an important situation for hurricane anchoring...

I'm open to other opinions if people think a different manufacturer of anchor would be better.

I'm also looking for advice on which size to get in the Spade. Spade's sizing recommendation chart is shown below. My Hunter 410 is 41 feet and displaces 20,000 lbs. That would put me in the 33 lb on length, or the 44 lb for weight as their recommended anchor. Since it's meant to be a storm anchor, I figure that means I should look at the 55 lb or 66 lb versions. It's almost a $300 price difference, which will sting but in the realm of preventing hurricane damage I'll gladly take the hit if the 66 lb is the right choice. But I'm interested to hear if people think it is worth it, as I do see several potential downsides to the big boy:

1. Will I have a lot of difficulty deploying/recovering an anchor that big? I have an electric windlass that I believe will handle the weight. But the anchor will be too big for my bow roller, so I'll have to heave it inboard from the roller by hand when recovering.

2. I wonder if I'll have problems setting it? Does a bigger, heavier anchor take more force to set properly? Will my boat have enough weight to get it to dig in?

3. It will be a huge PITA to store. It's heavy, so I'd want to find somewhere low and central to stow it when cruising, but I don't have many good options for something that big and awkwardly shaped. The easiest spot would be in the lazarette right aft. Is it worth worrying about 65 lbs back there?

As always, thanks to everyone for sharing your expertise and experiences!
