Bruce & Claw Anchor
Bruce & Claw Anchor
The Bruce Anchor is known generically as a "claw type anchor". Claw-types have the good reputation of not breaking set, quickly in most sea beds and although not an articulated design. They offer a fairly low-holding most power to weight ratio and generally have to be over-sized to compete with other types anchors.
Bruce & Claw Anchor type
Claw & Plow Anchors - Use a plow-or claw-type anchor in hard bottoms or heavy sea weather conditions.
anchors have no stock near the flukes.When anchor drag, they will
roll back onto their flukes and reset into the seabed. The CQRdesign and Bruce (claw) are the most common anchors used by boating vessels worldwide.
Plow anchors - top manufacturer is Simpson Lawrence in Scotland.Most other plow-anchors manufacturers simply copy of their patented design.
shape and weight cause the single heavy fluke to bury itself as
anchor is pulled from ahead.Perfect works, it really does work in most bottom conditions and is the anchor of choice for many ears. They claim that the precise design is important for its most holding power, and that a few degrees difference in the design can make a substantial difference. The illustration below at right.
The Bruce anchor
The *Bruce* anchor is a particular patent that is among the
anchors of choice for saiiors and long cruising boaters. specially Designed initially to hold floating oil rigs in the stormy hard sea conditions, the Bruce anchor has
no moving parts yet will bury and hold extremely well in many bottom conditions. Its only real drawback is its physical size, which makes it
more difficult to stow securely. The illustration below at feft.
The Bruce anchor- has some of the advantages of both the plow(Lighter
than the plow) and the lightweight. It is Its single weak point
appears to be the tendency
of the shovel-like flukes to dislodge and clog with solid chunks of clay, preventing it from resetting.

The Bruce anchor
- yacht anchor Choice
which was made for drilling rigs, has
been one of the very popular anchors on yachts.This Anchor, easy to handle without movable parts, digs in well in sand bottom, mud or gravel,
but is less-reliable on rocks with lots of seaweed.Bruce can be difficult to break
loose when weighing anchor.
/Claw anchor in popularity as a primary
anchor on boats longer than 30 to 33 feet.
One-piece design anchor - The Bruce no moving parts manufactured(up to a size of approximately 14,5 01b -7 tons) in heat-treated cast steel provides strength,It possesses a highly efficient curved fluke( there being no stock) area and subsequent fluke anchor action. The anchor with very good holding power is maintained roll-stable by the stabilising forces produced by the fluke extensions.
A anchor claw type design made in steel can penetrate weed
to find the underlying sediment on a sea bottom and may even find
something to grip on a rock bottom. On the other hand, although
it holds well in sandor mud. It's a good choice for primary anchor,
on a boat or yacht, it is unsuitable for storage on deck with bow
roller. the Bruce gives it great holding and strength ,good holding
in sand, mud and perfect for rocky ground, are normally permanently
fitted to the bow of larger yachts and boats.
Its holding power may be matched or other types anchor but the ease of getting it down on many types of bottom.

Bruce - Stock & Stockless Types anchors
The Bruce(design with no moving parts) and Plow anchors are of the stockless type.
Others are classified as being of the stock type, although the stock, may be at either crown end or the ring of anchor. those types, such as the light-weight anchors , with the stock at the end-crown , have a fixed stock.
All designs where the stock is at the ring end, such as the kedge anchors types,the stock is loose and can be folded and provides for better stowage of the anchor, and a key is required to pin the stock of a kedge in it's open anchor position when set up ready for use.
Bruce(design) anchor - A good efficient design with no moving parts.A trade name to describe a specialist anchor manufactured by the anchor brand "Bruce Ltd". - incorporated the anchor-hook-effect and the Spade effect of the stockless anchor to produce a maximum holding power with no moving parts.
The rule of thumb
The rule of thumb for Bruce anchors is 2 x the boat length in chain then rode. And use SS wire on the breakaway connection. Not a plastic zip tie. That may work in shallow water but not our deeper waters.
Bruce ...and weight
There is a wide choice of anchor main designs and their devotees. General use today are the 'Plough', 'Danforth', 'Fisherman' and 'Bruce'.
The Bruce anchor designed originally for maintaining the position of oil rigs and are not suitable for normal use in boats. They are claimed to give a better grip and holding power for lessweight but have many cases where they have begun refused to rebed themselves and dragging in bad sea conditions.
Some people love them and others hate them. But new anchor-designs come and go, the Bruce design is now firmly established as one of the four highest standard anchor designs.
ready for instant use "Bruce anchor" stowed on a bow roller
"I once experienced this when being dragged backwards through the moorings at Queenborough on the River Swale in a friend's 24-ft. motor cruiser at one o'clock in the morning. Admittedly it was at the height of a gale, but the anchor refused to hold us no matter how much chain we let out."
The problem is probably one of anchor weight, as the recommended sizes from manufacturers of Bruce anchors are generally smaller than for plough and "Danforth" and the lack of Enough weight makes digging in bottom more difficult than Heavy Anchor. Generally Using a larger size and weight obviates this nasty problem.
Bruce for for a bit of inshore fishing edges
Use a Bruce anchor everywhere in the Solent and Southampton water, probably the best all round shape for mud, sand, shingle etc. You'll probably find a 2-4kg will be ideal, same length of chain as your boat, in 6mm. If I recall, the sizes go 2kg then 5kg, I think the 5 might be overkill for you, but if the 2 drags, use a bit more chain. They have amazing holding power for Thier size though. You'll need at least 3 times the depth of water in rope, bear in mind, even if you don't intend to fish deep water, you may need to anchor in an emergency. People wouldn't go less than 50m personally, but it all depends on depths tide flows etc as i said im not local to your area.
People prefer a bruce anchor on a rib as they tend to be a little less sharp, less 'finger trapping in a hurry' and for the solent area the holding should be great, 5kg with 6mm should be fine if you've got 8-10m of chain - it's tempting to go for heavy anchor with small amount of heavy chain but the lighter items with a decent length of chain should be surprisingly good and much easier to handle.
Claw anchor vs plow anchor/weight
"I use a 13 lb for my 21 ft North River Seahawk. I go to a 25 lb version in the fall when we're fishing deeper water."
The 13lb is good in up to 40 feet of water in strong current. The bigger anchor gets down faster when dropping in current, is the main reason I use it. I think the 13 lb would hold fine, but when you are dropping in 60 feet, it can flutter on the way down.
Plenty of chain and scope
Makes a big difference in that it absorbs shock and keeps anchor more horizontal. With 50 ft of chain.. more chain in the secret to holding bottom. Rule of thumb, at minimum the chain should be as long as the boat, double is better.
Set anchors carefully and never just throw them in.
35lb CQR with all-chain on a 32' cruising sailboat (10-ton displacement) will keep you safe.
"I use a 10lb Bruce with 10' of chain then nylon rode on a 25' Carver. Usually a small Danforth for just quickie anchoring in a 17' walleye boat. I once set a mooring using three 25lb Danforth anchors with all-chain to a swivel and nylon rope to the surface and used it in La Paz, Baja CA for months with trips out to the islands and back."
Plow type anchors (CQR and Bruce) set better in conditions where the current or wind swaps. Danforth type anchor can have problems in those situations. Always use at least some chain. Also safety wire your shackles.
The general consensus on - Let's get the RYA ratio right first
4:1 if chain only, but ribs don't carry all chain, way too heavy. So 6:1 using warp with about 2m of chain to help it bed in. That's 6 times your max depth, realistically you can get away with 4:1 if you are sensible on the conditions you go out in. Personally you won't find a better holding than a Bruce.
If storage is an issue look at a Danforth as they fold flat. Grapnel or the folding anchors as some call them are not that good as they lack surface area and grip into the sea bed. Your call, but when the brown stuff comes out of the fan you will not regret using a Bruce.
