Harken MKIV Unit 1 Ocean Furling System, w/Clear Anodized Foils, Toggle Sold Separately - For Boats 28'-36'
New! Harken introduces the MKIV Ocean furler, specifically configured for the cruising sailor. It is engineered with strength, longevity, ease of use, and at the right price without extra features cruisers might not need.
Low-friction efficiency for easy furling and reefing
- Multiple rows of Torlon ball bearings in high-load areas minimize friction.
- Stacked bearing races evenly distribute radial and thrust loads; drum and halyard swivel turn freely under load.
- Foils rotate around around headstay so headstay load is isolated from the furling unit for easy furling
- Large inner spool diameter increases mechanical advantage for powerful reefing and furling.
Stands up to Sun, Salt, and Time.
- Aluminum line guard, torque tube, and swivels deep-saturation hardcoat-anodized, UV-stabilized for durability.
- Line guard polyurethane-coated for wear protection.
- Specially formulated low-stretch black line is abrasion and UV-resistant; standard on units 0,1,2.
- Round, clear-anodized aluminum foils handle extreme reefing loads.
- Triple-interlock foil joints withstand years of torque loading: foil connectors geometric shape interlocks with foil; secure with syringe-injected adhesive; screws provide final lock.
Single-Groove Foils Offer Smooth Sail Handling
- Precision-extruded, single-groove foils for smooth sail handling.
Designed for Easy Installation
- Small outside drum dimension fits narrow bows or belowdeck.
- C-shaped open connectors with low-friction plastic isolators easily slip onto headstay wire and into foil.
- Drum assembly fits over existing turnbuckle allowing easy length adjustment. Harken toggle assembly accepts standard turnbuckle using swage, rod, Norseman, or STA-LOK terminals.
- Eye-jaw toggle flips for fork or tang chainplate installation.
Easy to Maintain
- Bearings require no lubrication or isolating seals.
- Stainless steel link plates raise the drum and fit over existing turnbuckle, resist scratches, and can be repolished.
