Given that the weight of the chain is essentially the same... why would you want to get chain that is only half as strong? All chain, that is the same size wire is relatively close to each other in weight...
Now, if you were forced to use 1/4" chain for weight considerations, 1/4" G4 HT weighs 79 lbs. per 100' and is still stronger than the 5/16" BBB chain, with a SWL of 2600 lbs. This is a significantly lighter chain, since it is only 67% of the weight of the 5/16" BBB. I think this is the part that Cam has confused... since G4 HT chain is generally as strong as the next size up in BBB chain. 1/4" G4 HT is a bit stronger the 5/16" BBB, but weighs 33% less than the BBB. 5/16" G4 is stronger than 3/8" BBB, yet weighs only 69% of the weight of the 3/8" BBB.

|camaraderie||Jason...no Home Depot chain...you need chain designed for marine use and properly sized for your future windlass.|

If you have a 37' Morgan which weighs 1800 lbs you have the only one known to man! I'm sure you meant "18,000 lbs".
I'd go with 5/16" HT (G4 or G40...they're the same) chain. When you get your windless next year, be sure to get one with a gypsy to fit this chain.
How much chain? As much as you can afford/fit. I carry 200' of 3/8" HT chain with my CQR 45 as the primary anchor when outside the Chesapeake Bay, and find it's adequate. I much prefer all-chain rodes for my primary anchor. Also carry a couple of other anchors with nylon rodes attached to 30' of chain.

|jasonr575||is the chain in home depot the same as the chain in west marine?|

Newport...gotcha. I was responding on the basis of an all chain rode. In Jason's situation...no point in paying more for HT.
I don't know what BBB stands for...Acco doesn't say! Hot-dipped, short link galvanized chain at a good price...Best Buy for Boaters??? (G)

I haven't used it all that much, except for a week or so on a friend's boat, and will let you know what I think of it after a season of using it.

|jasonr575||i assume ht = hight tensile but what does bbb stand for?|
|05-02-2007 09:20 PM|
I understand wanting to have less weight in the bow but couldn't that be achieved with less chain? Do you understand what I'm getting at here? The whole point of the chain is that it is heavier than rope, so why spend the money on light hi tensile chain when its only a short amount of chain? I can understand if you're going all chain. Seems silly to me so I stand by my original remark. Buy the heavy stuff. 50ft doesn't weigh that much, especially on a Morgan 37.

Newport...if your chain is light and strong you don't have it weighing down your bow OR you can carry more of it without weighing down your bow. HT is about 30% less weight than BBB for a given size so that is nice if you are going to need an all chain rode and have a smaller/lighter boat where you want the ends of the boat level! In terms of breaking strength, BBB or HT in 5/16 are plenty strong enough for Jason's boat and displacement.
Jason...1. Bruce is no longer made 2. Lemar now produces a look-alike model called a Claw 3. I would not buy one.
4. The differences in chain are in the SIZE of the links and the building process. When you do get a windlass it will come with a capstan for a specific size and type chain. If you already have chain...you need to buy a windlass that can handle that specific type of link which can limit your choices and often there is ONE windlass which is perfect for the room and arrangement you have on your specific boat. If that ONE windlass can't handle your existing chain...you need to throw out your chain. That is why I recommended BBB to you as it is todays most widely used windlass chain.
HT in the 5/16 size is stronger and lighter and more expensive and WILL work in many BBB capstans but IS slightly different and MAY not be compatible with a specific capstan. BOTH HT 5/16 and BBB 5/16 are more than strong enough for your boat and storm loads.

|Newport41||Don;t want to jack the post here but I think this info would be good for Jason and myself. Why the heck would you want light chain? Is there something I'm missing here? I have a pretty good understanding of physics and light chain makes absolutely no sense to me. Isn't the whole point to absorb some of the load of the boat during a gust (and no I don;t mean strech, I mean due to sag in the rode from the chains weight), and to keep the load on the anchor horizontal? I agree that if you're trying to save weight than it's better to alot more weight to the anchor but isn't it true that heavy chain will help any anchor?|
