anchor systems - length of chain?

MaryBeth makes a good point.

It depends on a number of factors:
-- Length and displacement of your boat.
-- Where you sail, and the type of bottom you''re going to anchor (rocks and coral will chafe a nylon rode real quick).
-- Size/type of anchor.
-- How often do you anchor? If your a cruiser who spends most nights on the hook, you may want an all chain rode. For an occasional overnight (where you can usually pick a prime, sheltered spot to spend the night), you may opt for less weight.

Check the buying guides from several sources, and talk to people in your home waters with similar boats to see what they''re using. But remember, it''s worth the sleep and peace of mind to know you''re going to stay put though the night.

maxcontax,
Why do you say less chain is needed when using a fortress?

Chain Rode for fortress

Dennis, it is my understanding that the Fortress relies on design -- more than mass -- to set. The initial setting of a fluke anchor ie. "How you set it"-- seems to have more impact than the mass added by chain. (Intuitively I balked at this.) That is their appeal. My new Fortress FX11 has not actually been in conditions to pass comment on how it works w/ 10'' of chain on a nylon rode. (I am sticking with a Bruce as a primary. Also, I just may be getting away wit it because my boat is a Catalina 22 which may weigh 3000 lbs tops when cruising.

maxcontax,
Good evening.
I dobn''t think the anchor has alot to do with the weight or amount of chain that should be used.Anchor doesn''t dictate to chain... chain dictates to anchor, so to speak.
Chain creates a caternary...why would you not want that?

Every anchor design I am aware of benefits from having the "pull" of the rode as horizontal to the seafloor as possible. Since heavy chain improves this over nylon rode, chain has to be better in that respect.

JMHO,

Duane

The latest issue (6/02) of Sail magazine has an article on anchoring around reefs. It seems there may be times when you don''t want the rode (including the chain) to lay on the bottom.

Dennis,

In complete agreement with you but the original query remains elusive: how much is enough? Anchors rely on two major components to set: their design/size and their rode. The query is a good reminder that it is the whole composition of the anchoring system that creates the result and not the anchor, or the chain, or the scope, not to mention the bottom and sea conditions!
It''s worth figuring out for your boat and getting really good at it, if it gets you away from congestion and fees at the marinas. It is also nice to know about when you climb onto a charter boat and inspect the setup--it will tell you where you can and cannot anchor.

anchor systems - length of chain?

From my experience with Fortress, it often sets more reliably, especially in soft mud, when set with a short scope. However, once it''s set, I would always feel comfortable with more, rather than less, scope. How this relates to the issue of resetting itself after changing tides or wind direction, I can''t say.

norm,
Danforths have a bad habit of not resetting themselves after breaking-out because they hold in their flukes mud rocks grass etc.
Fortress danforths are light and flip over easier than a steel danforth.If a danforth flips over and is clogged,it won''t reset.
