Stainless Dual-Roller Bow Guide – 328×70 mm (Heavy-Duty)

This stainless double-roller bow guide (328×70 mm) is engineered for serious loads and trouble-free anchor handling on larger boats. With an overall length of 328 mm (over 32 cm), it’s significantly longer than standard rollers, providing additional leverage and control when retrieving the anchor. The twin-roller system is the standout feature of this model: instead of a single wheel, the anchor rode/chain runs over a forward roller (near the bow tip) and then onto a second, aft roller. This distributes the force and maintains a fair lead of the chain at all times. For example, when the anchor is being hauled up to the bow, the forward roller carries the weight of the anchor itself, while the rear roller guides the chain smoothly towards the windlass or bow hawse pipe on deck.

Construction & Material: It features a heavy-duty U-channel stainless steel frame built to handle strain. The frame is made wider (70 mm) to accommodate anchors with broader stocks. All connecting hardware, including the roller axles, are stainless steel. The rollers themselves are typically made from tough black polymer (or composite) that’s highly wear-resistant and capable of withstanding the weight and abrasion of metal chain without damage. There’s a hole positioned to allow a locking pin to be inserted once the anchor is fully in – letting you secure the anchor’s shank or chain to keep it absolutely fixed when the boat is underway.

Anchor Compatibility: Thanks to its length and dual rollers, this guide is suitable for heavier anchors – for instance, a 10 kg Britany or Delta, a 12 kg Bruce, a 15 kg Rocna, or similar anchors in that category. Even Admiralty-style anchors (with long shanks and crossbar) or plow anchors with longer stocks can be accommodated. The 70 mm internal width permits anchor shanks about 50–60 mm thick (as found on ~15–20 kg anchors) to sit comfortably between the cheeks. 8 mm chain will run flawlessly; even 10 mm chain can be handled as the rollers are adequately sized.

Practical Benefits: In everyday use, the dual-roller guide greatly reduces any “jerking” of the anchor during retrieval – the anchor is brought in fluidly and aligns into its stowed position. If the boat is pitching or the pull angle is not perfectly straight (such as in a crosswind or current), the two rollers help re-direct the chain without it jumping off the roller. This prevents those mishaps where the chain might skip out of a single short bow roller due to a shifting angle. The longer reach also keeps the anchor farther forward of the bow, which is a plus for boats with pronounced flared bows – there’s less chance of the flukes hitting or scratching the hull before the anchor is fully up.

Installation: This roller requires a solid installation with at least four high-strength bolts (stainless M8 or M10 bolts recommended, matching the pre-drilled holes). Given the high loads, it’s advisable to reinforce underneath the deck (using backing plates or large washers, or tie into an internal stem fitting). Many yachts have dedicated reinforced bow plates for anchor rollers – this unit is meant to replace or upgrade an existing setup. After installation, check alignment with your windlass: the rear roller should line up nicely with the direction the chain enters the gypsy, to ensure smooth operation.

With the dual stainless bow roller 328×70 mm, you’re investing in a professional-grade component of your anchoring system that will withstand the rigors of heavy anchors, long chains, and rough marine conditions. This piece of equipment is favored by experienced mariners who seek safety, convenience, and durability for their primary anchor handling gear.
