2025 NEW PRODUCTS USE WITH 2024 CATALOG

Welcome to the 2025 Harken Marine Catalog Supplement Greetings. We produce this supplement every other year to update our larger biennial catalog. Inside you will find new products we are introducing this year and some expanded information, such as early market acceptance and perhaps rigging ideas about a few products that just barely made it into our 2024 catalog. Remember, you can always find our most up-to-date product lineup at www.harken.com or in our countryspecific websites. Lastly, there is a navigable PDF version of our current catalogs that you may download at any time. You can find...

This addition to our small but mighty Fly block assortment has been developed to increase the efficiency and working load capacity of the top block in our evolving ILCA 6 and ILCA 7 boom vang systems. Its unique design allows integral attachment to a new-generation vang key. In ‘non-ILCA’ applications, the block can be attached without the vang key using the included clevis pin and ring ding. The large hole in the bearing axle was designed to accommodate a soft becket attachment point. The sideplates are anodized aluminum. The sheave and inner bearing race are stainless steel as are the 15 bearing...

Zircon Blocks The Family Is Growing How do we know when a product is making a difference? Riggers and sailors send photos and impromptu reviews of how they’re using the product in different ways. And then they start asking us to make more. They want them bigger and stronger and they want more sheaves and they want beckets so they can improve the performance of more systems. And you know what? They ask for smaller versions too for dinghy control lines. So here we go. We’ve been saying all along that Zircon ceramic blocks are uncommonly responsive. Trimmers certainly have been using them to feel...

40 mm Zircon Cat Mainsheet System This is the newest entrant in the ongoing process of creating highefficiency mainsheet systems that keeps up with ever more aggressive sailing styles in the Olympic NACRA 17 or other Grand Prix multihulls. At the heart of the 2801 system are 40 mm Zircon sheaves that provide incredible friction reduction while generating 30% less airflow disruption and clearing the tiller more easily. There’s a swivel on both top and bottom units to allow for better alignment with load and position of the crew. Sailors are still free to select any of the Harken Power3 ratchet...

A first! The new carbo twing block features a spring-loaded top-opening mechanism so you can pop it on or off the sheet very quickly whenever the breeze dictates. And practice makes doing it one-handed a snap. Carbo sideplates and sheave give it the toughness to survive impact as you pull it down tight to the deck.

40 mm Carbo Double Swivel Symmetrical Fiddle, Fishing Pulley The new Harken #2184 was designed to improve the deployment and retraction responsiveness and the precise presentation of bait teasers aboard sportfishing boats. The pulley features two back-to-back 40 mm sheaves which make it symmetrical and balanced. This is the first fishing pulley with a swivel on both ends—most have a single swivel at the head. This eliminates the need to manually rig another swivel at the opposite end. Getting rigging done and lures in the water is much faster. Symmetrical, balanced, and mated sheaves prevent...

Fixed Tulip Blocks This workhorse equipment is designed to mount easily and provide unobtrusive, economical strength. Their wide, line-friendly tulip sheaves make them efficient for applications where slight lead angle misalignments would otherwise lead to off-center loading and increased friction. They are also helpful where the lead angle changes as it does in some outhaul systems as the boom goes in and out and across the boat. Mastbase block: In these applications, one fixed tulip block can replace a block plus a baseplate plus a shackle or loop. Over-the-top models are designed to facilitate...

FlatWinder Powered Block FlatWinder Sensor The FlatWinder Sensor is introduced as a kit that can be added to every FlatWinder application we’ve ever produced at Harken. When added to a FlatWinder, its purpose is to stop the motor at specified points, even if the button to activate the FlatWinder has been pressed. For example, it can stop the movement of daggerboards, traveler cars, or extendable leisure platforms. The Sensor kit includes an electric box with a dedicated Harken DualFunction Control Box. Depending on the requirement of the application, the sensor can be either inductive or magnetic....

This new big-boat, side-opening twing block is designed to be opened and closed one-handed using the radiused thumb button set in the sideplate above the sheave bearing. That button is partially recessed to protect against inadvertent opening. Rigging a twing line is generally accomplished to leeward while leaning overboard to access the tensioned sheet. To help add crew safety, the button is spring-loaded so opening and rigging the block becomes a true onehanded operation. The block is made of aluminum with Torlon® bearing balls running in curved races recessed within the anodized sheave. Sideplates...
