Spade Anchor High Performance Anchors

When You Want High Performance, You Have It With Spade Anchor

The Spade Anchor is one of the most versatile anchors in the marketplace today. With this revolutionary product there is no need to worry as the Spade Anchor product is safe, easy to use, and is available in sizes to fit any boat. Dream Catcher Yachts is proud to be a Spade Anchor Dealer.

Take a look at the following features of the Spade High Performance Anchor:

  • It doesn’t require the use of any special mooring line, or anchoring technique
  • It can be used with a low rope-length to depth ratio
  • It is painted bright yellow so you can visually check how well it’s dug in
  • It is self-launching and self-retrieving
  • It fits snugly on most bow rollers, presenting a rounded forward surface
  • It can be easily dismantled into shank and body for storage or transport

This product’s unique design is what makes it so effective. The Spade Anchor’s shape allows it to plow the sea floor as it moves through it. Once within the sea floor, the concave shape of the anchor is designed to compact the sea floor and not move. This product is so versatile it is available in three materials (steel, aluminum and stainless steel) and ten sizes! All Spade Anchors, regardless of size or material, will work with the same efficiency.

A handy dimensions chart will assist in helping you choose the right model and the Frequently Asked Questions will address the most common purchasing and selection concerns regarding this fine product. Spade Anchor products come with a satisfaction guarantee backed by warranty. Take a look at some of the compelling testimonials, photos and videos, including the Boat Show YouTube video below to get a better sense of why we believe this is the best anchor on the market!

Technical Details

1. Digs in instantly

As the anchor is the boat’s most important piece of safety equipment, it must be available and, once deployed, it must set immediately.

The Spade Anchor has only one tip, and it is very sharp. Nearly 50% of the anchor’s total weight is applied to this tip. This unique characteristic gives the SPADE anchor a superior ability to penetrate the sea floor, even into hard sand and through weeds.

The sharper the tip, and the greater the weight on it, the more rapidly and reliably it will penetrate the sea bottom.

2. Penetrates deep into the sea floor

Many existing anchors have their preferred sea bottoms : they are not versatile devices ! Many sailors carry several types of anchor, imagining each will suit its particular type of sea bottom. This is, at best, an inconvenient solution for the problem of variable sea floors ; but at worst, in an emergency, it can be disastrous. You normally do not have the time, or the ability, to know what kind of bottom you will meet – especially in an emergency.

The angle of attack at which an anchor meets the bottom dictates how well it will penetrate the bottom. The SPADE anchor has been designed to meet the bottom at an angle like that used with a chisel working wood : it has to penetrate. Many other anchors meet the bottom at an angle like that used on a spreader pushing filler : they resist penetration. SPADE’s logically ideal angle of attack, together with its sharp edges and point, explains why the SPADE anchor has such superior penetration.

In dense weeds, the SPADE’s unique design allows it to penetrate through the weeds, before digging deeply into the seabed below.

The shape of a “cutting tool” is the only one designed to penetrate, and the SPADE anchor is the only one to have these design characteristics (patented).

Typical behavior of plough anchors, or of flat anchors without a stabilizing strut. The anchor’s hold is cyclical: dig in, release, dig in, release …. in some cases the anchor will not be able to dig in again.

3. Once set, the anchor gives the maximum holding power without dragging

An anchor that digs in but doesn’t hold is worse than useless, it is positively dangerous. On arrival you check your anchor’s set, and everything seems to be in order. But it’s a false sense of security when the winds get up, such an anchor lets go, and the boat starts to drag.

Over many years, aeronautical engineers have devised a system to measure the resistance of various profiles to movement through a fluid medium. This measure is called the coefficient of resistance of the profile. For an engineer, “fluid medium” includes all materials that can deform to allow an object to pass through : “fluid medium” includes all materials in the range from air, water and other liquids, to sand, soil, and sea floors.

The concave profile has the highest coefficient of resistance (1.7) for moving through any fluid medium. Strangely, anchors have never been designed with profiles much beyond the flat profile (coefficient 1.2), and most have used a chevron profile (coefficient 0.5 – 1.0).

The SPADE anchor is designed around the concave profile, which ensures that, once buried, it will compact the sea floor material within its form, rather than sliding through it like a plow. It must offer much higher resistance to movement than anchors using other profiles.

The SPADE anchor is the only one to use this patented profile.

4. The anchor offers constant, and maximum, resistance to dragging

A basic requirement of an anchor is that it must not let go under strong load. If a strong wind causes the anchor to let go, the boat will turn side-on to the wind, and soon start moving with speed. As the boat gains momentum the anchor will never be able to hold again.

Numerous comparative tests have shown how conventional anchors work. It appears that few are able to reliably resist dragging.

The SPADE anchor, during the same type of tests, has shown an exceptionally high holding power. Equally importantly, when tested under loads so high that the anchor must begin to move through the bottom, SPADE anchors have consistently offered a very high and fairly constant resistance to movement.

Typical behavior of plow anchors, or of flat anchors without a stabilizing strut. The anchor’s hold is cyclical: dig in, release, dig in, release …. in some cases the anchor will not be able to dig in again.

Typical behavior of fluke anchors with a stabilizing strut. The anchor drags, often at the worst moment, and will never dig in again : it skates across the bottom on its side.

The SPADE anchor always remains deeply buried, without cyclic (or corkscrewing) behavior, or releasing its hold. It continues to assure maximum holding power even under extreme load.

5. The anchor keeps on holding, regardless of the shift in direction of either the wind or the current

With a major change in direction of wind (or current) most anchors will break free. The anchor then drags, hopefully for only a few meters, before setting again under the new load direction.

Thanks to its concave profile and to its high holding power, SPADE anchors pivot within the bottom, towards the new direction of load. As the new load comes on, the SPADE anchor just sets in a little deeper, and keeps on holding.

6. The design does not allow the anchor line to become snagged by the anchor

When an anchor is first dropped, or during a change in direction of load, it may become entangled in its rope. When the load comes on, the anchor cannot then react as it was designed to, and can only drag along the surface of the bottom. Anchors that can allow this to happen are poorly designed, and dangerous.

Thanks to its neat design, there is no part of the SPADE anchor that could entangle the rope. During independent tests, attempts have been made to tangle the anchor in its rope, but under load the SPADE always takes up its correct alignment.

Remember MURPHY’S LAW : if something can go wrong, it will do so at the worst possible moment. With SPADE anchors, it cannot go wrong : the rope cannot entangle in the anchor.

7. The anchor is strong enough to withstand very high loads

An anchor that holds on strongly to the bottom, no matter the load, must be physically very strong. It must not deform or break under extreme loads.

SPADE is designed for strength. The shank is designed to be strong yet light, with the classic trapezoidal profile (like a box girder) being used in our welded models. With the new, fabrication technique now used for most of our models, the shank has an “I” profile for the same reasons. The shank sockets into the body of the anchor, with a socket supported by double triangulation, giving a rigid and indestructible joint.

The shank profile and the coupling to the blade, together with the use of high resistance steel alloys give the SPADE anchor very high mechanical resistance.
