Electronic Windlass Control Panels with Chain Counters

Imtra offers two styles of electronic windlass controllers with integrated chain counters. The Auto Anchor 500 comes in two versions: one for all chain and one to accurately monitor rope/chain combination rodes. These innovative controllers feature a large LCD display, backlighting for nighttime operation, choice of measurement in feet or meters, safety lock and a clever "one touch" automatic function to deploy or retrieve a preset amount of chain. Required mounting area: 51/2" x 51/8".

Electronic Windlass Control Panel

Our space-saving, dash-mounted windlass control features a special "slow-retrieval" mode to help safely retrieve those last few feet of rode and stow the anchor. A separate on/off switch (with indicator light) will automatically shut down panel after 75 seconds - a key safety feature! Size: 2" diameter x 2" deep.

Anchor Chain


Anchor Chain & Rodes

ACCO ® Anchor Chain

Imtra offers the popular ACCO brand of anchor chain in three configurations; all meet ISO specifications. ACCO's Grade 40 (G4) hot-galvanized, high-tensile has become an industry standard, combining high strength in a short-link chain that runs easily in anchor windlass gypsies. Although not as strong as the G4, ACCO's Grade 30 BBB-chain (3B) also runs well on many windlasses for a lesser price. ACCO's 316 stainless steel chain comes in all popular link sizes and makes an attractive and functional alternative to galvanized chain, especially on rope/chain combination rodes.

Snubbers & Chain Hooks

Anchor snubbers are an important add-on when using an all-chain rode. After setting the anchor, simply slip the hook onto a link of chain and tie off the 3-strand nylon tail. You can then let out additional chain with the windlass, which transfers the anchor load to the snubber from the windlass. This makes for an easier and quieter ride as the nylon tail will stretch slightly as the load of the boat on the anchor changes. We use high-strength ACCO chain hooks in our snubbers and offer these as separate items so you can build a snubber to fit your own specifications.

Anchor Tensioners

Imtra anchor tensioners hold the anchor snug against the bow roller. The construction is of rugged stainless steel for long life in a marine environment. The clamp has a safe, over-center action with a maximum of 21/2" of take-up. The quick-release locking pin has a retaining cable. Suitable for anchors to 100 lbs. and for chain sizes up to 1/2".

Anchor Rollers 14

General Purpose Rollers

Imtra also offers rollers for general purpose applications and may fit a wide range of anchor types and sizes.

BR-1 This roller is designed to fit over the stem plate of many sailboats using existing bolts. This keeps the deck clear and offsets the roller so the anchor does not interfere with the forestay.


BR-5 A heavier duty version of our popular BR-3 platform roller, the BR-5 will hold anchors to 80 lbs.


BR-3 Series These platform-mounting rollers accept a range of anchor types. Available in standard and narrow widths. Flared flanges hold the flukes of Danforth-type anchors securely in place when stowed.

IABR-3 standard width IABR-3N narrow version

BR-2 Series These small utility rollers can be used as fairleads, for controlling lines or for stowing small anchors.
