Extendable bow roller designed for safe anchoring and stowage of Bruce-type anchors from 10 to 15 kg, particularly suitable for boats with vertical bows. Made of mirror-polished 316SS, it provides corrosion resistance and reliable performance in marine environments. It features a gas spring system that extends the roller up to 220 mm, allowing the anchor to move clear of the hull before deployment. It also incorporates a tilting mechanism that enables controlled self-launching of the anchor at a safe distance, preventing impact against the hull during anchoring operations. The design enhances safety, control, and efficiency, offering a practical and functional solution for bow installations.
