316 Stainless Steel Trefoil (Bruce) Anchor
The 316 Stainless Steel Trefoil (Bruce) Anchor is a trusted anchoring solution designed to deliver exceptional holding power, rapid setting performance and long-term durability in demanding marine environments. Manufactured from premium marine-grade 316 stainless steel, this anchor provides outstanding resistance to corrosion, making it ideal for use in coastal waters, estuaries, harbours, marinas, rivers and offshore applications.
The Trefoil, or Bruce-style, anchor is one of the most popular anchor designs in the marine industry due to its ability to set quickly and maintain a secure hold across a wide variety of seabed conditions. Its distinctive claw-shaped profile naturally rotates into the optimum position when deployed, allowing it to dig in efficiently and provide dependable holding power with minimal effort.
Why Choose a Trefoil (Bruce) Anchor?
Unlike some traditional anchor designs that require precise positioning or can struggle to reset when wind or tide changes direction, the Trefoil Anchor is designed to re-establish its grip quickly. This makes it particularly suitable for areas with strong tidal movements, changing weather conditions and busy coastal environments.
The one-piece construction provides excellent strength and reliability with no moving parts to wear, seize or fail. It is widely chosen by leisure boat owners, commercial operators, fishing vessels and harbour users who require a dependable anchor that is easy to deploy and recover.
Suitable Seabed Conditions
The Trefoil Anchor performs exceptionally well in:
- Sand
- Mud
- Clay
- Shingle
- Gravel
- Mixed seabeds
- Soft harbour and marina bottoms
- Tidal river environments
Its claw-shaped design allows the anchor to penetrate and grip the seabed effectively, providing strong holding power in conditions commonly found around the UK coastline, inland waterways and commercial marine installations.
Common Applications
- Motor cruisers and powerboats
- Sailing yachts
- RIBs and inflatable craft
- Fishing vessels
- Commercial workboats
- Pilot boats
- Harbour and marina operations

Benefits of 316 Stainless Steel
Manufactured from high-quality 316 marine-grade stainless steel, this anchor offers superior resistance to saltwater corrosion compared with standard steel anchors. The polished finish not only provides a professional appearance but also helps maintain its condition in harsh marine environments with minimal maintenance.
For boat owners looking for both performance and appearance, stainless steel anchors remain a popular upgrade from traditional galvanised alternatives.
