Mantus M1 Galvanised Anchor

The Mantus M1 Galvanised Anchor is designed for exceptional holding power, making it a trusted choice for cruisers, racing yachts, and day sailors.

Whether you're anchoring in dense sea grass, soft mud, or rocky seabeds, the precision-machined fluke and roll bar ensure rapid setting and secure holding. Unlike traditional anchors, the sharp chisel tip allows it to dig in quickly and stay buried, even in challenging conditions.

Built from high-tensile galvanised steel, the M1 is strong, durable, and corrosion-resistant. The bolt-together design makes it easy to store, allowing you to keep a spare onboard without sacrificing valuable space.

No matter where your adventures take you, the Mantus M1 delivers confidence and security at anchor.

Why Choose the Mantus M1?

• Fast-Setting Design – Digs deep on first contact, ensuring a reliable hold.
• Maximum Holding Power – A wide fluke design increases resistance for stability on soft, hard, or weedy seabeds.
• Roll Bar Technology – Optimises the penetration angle for perfect setting every time.
• Durable Galvanised Steel – Made from high-quality steel with no cast parts for superior strength.
• Heavy-Duty Construction – The shank and fluke are securely welded and bolted using oversized ASTM-certified bolts.
• Easy Storage – Breaks down for compact storage, allowing you to carry spares without taking up valuable boat space.

Choosing the Right Size - See Selection Chart in Images

Selecting the right anchor size depends on your boat and the conditions you expect to face. Mantus categorises their anchors based on wind strength and seabed conditions to ensure optimal holding power:

• Day Anchor – Ideal for winds up to 30 knots, suitable for fair-weather anchoring.
• Cruising Anchor – Designed for winds up to 50 knots, providing reliable holding for extended stays at anchor.
• Storm Anchor – Built for winds above 50 knots, offering maximum security in extreme conditions.

Mantus anchors are designed with conservative sizing to ensure superior performance, even in poor holding conditions like low-viscosity seabeds. While some brands offer smaller anchors claiming higher efficiency, Mantus prioritises real-world safety and reliability.

If you frequently anchor overnight or in unpredictable conditions, it's always best to size up for added peace of mind.
