Sacrificial Block Anode 1.8kg – Zinc-Plated Strap, 160 × 80 × 23mm

Your anode's dissolved. You're at the marina, hull up, staring at a bare stud where protection should be. This 1.8kg block anode is your fix. The zinc-electroplated mild steel strap runs 290mm – long enough to cover even the widest stud pitch on your keel or transom. Block measures 160 × 80 × 23mm. Bolt it on, get back in the water. And here's the trick worth a minute of your time: buy two. Drill both holes now. Fit one, stash the other in the shed. Next time it's gone, you're not waiting on a delivery
