Anne’s Mushroom Anchor Moorings

Whether securing a small sailboat or a 200 foot power vessel, Anne’s hurricane-tested anchors represent the ultimate in permanent moorings for owners who insist on maximum protection.

Anne’s Anchors Superior Design & Materials

Originally designed on Cape Cod, Anne’s mushroom boat anchors are manufactured in the USA from custom quality steel instead of cast iron and are available in weights up to 2,000 pounds. Anne’s all-steel construction mushroom anchors offer several advantages over imported, cast iron models including greater material strength and more holding power. Presented below are design attributes that highlight the superiority of Anne’s Mushroom Anchors.

Cast Iron

  • Small eyelet wears out quickly
  • No counterweight
  • Bell 16,000 psi tensile strength
  • Breaks in bell are irreparable


  • Extra wear area
  • Heavy steel counterweight
  • 70,000 psi tensile strength
  • Anchor repaired by welding

Anne’s Mushroom Anchors feature a wider bell diameter, more aggressive biting edge, plus a heavy counterweight to hold the anchor at the correct set position. Absence of a counterweight allows the anchor to align into a vertical position that can cause the chain to wrap around an anchor’s shaft and lose holding power.

Additionally, Anne’s Anchors are designed to eliminate corrosion problems often associated with cast iron mushroom failure. Also, by welding both sides of the bell and counterweight, formed joints have the same 70,000 psi tensile strength as the anchor’s base steel material.

“During the late summer of 2011 Pioneer installed a new mooring system for me in New Bedford Harbor. I had been aware of Steve Gomes’ excellent reputation, so my choice of mooring provider was easy. Steve acquainted me with the available ground tackle options and the pros and cons of each.

Taking into account my needs, Steve designed a mooring system with an Anne’s Mushroom Anchor that kept my Swan-47 ARISTEA secure through Hurricane Irene while other boats in the harbor experienced problems.

Pioneer demonstrated why it has earned such a high reputation for supplying safe and dependable moorings and for responsive service at a reasonable price.”

Proper Seating of Anne’s Mushroom Anchors

For more than 150 years, a well-seated mushroom anchor has been the standard permanent mooring of choice at most east coast harbors including SouthCoast, MA and Rhode Island.

Anne’s Mushroom Anchors accommodate bottom conditions exceptionally well which are likely to be a combination of mud and sand with varying amounts of rock and clay. Accordingly, most Harbormasters specify mushrooms anchor moorings where the long-established pull test rule of thumb that “a mushroom anchor will hold 10 times its weight” is still valid today.

Mushroom anchors of all kinds seat readily in soft sand seabeds, but must be jetted in mooring locations where the sand is so hard that the mushroom bounces along the seafloor. Along with local Harbormaster requirements, Pioneer technicians will advise you on the proper seating method given the bottom conditions in your mooring area.
