16 mm Harken Carbo Block

16 mm blocks offer very high working loads in an extremely small, lightweight block. These diminutive blocks feature a patented bearing system using stainless balls in a captive, grooved race and provide a 250 lbs ( 113 kg) safe working load. They are perfect for the new, smaller synthetic control lines found on high- tech dinghies and are the obvious choice for competitive racers. The 442 uses a spacer and the 404 uses an O- ring to keep the line in the sheave during intermittent loading.

Harken Micro Block

Micro blocks are small, lightweight, free running blocks. They are ideal for use on sailboards, smaller dinghies, and for lightly loaded control lines on boats of all sizes.

Harken Bullet and Big Bullet Blocks

Use ball bearing Bullet blocks to lead control lines with a minimum of friction. A wide range of variations let these blocks adapt to almost all control line situations. Use exit blocks with cams on masts for halyard controls and under decks and at mastbases. Wire Bullet blocks use roller bearings. The 392 is a downhaul/cunningham assembly for catamarans.

Harken Dinghy Blocks

Dinghy blocks are lightweight, low-profile blocks designed for use on dinghies and for control lines on larger boats. The in-head shackle system keeps the length of this block very short. These light-duty blocks are not for use on heavy course racing keelboats, scows, or catamarans.

Harken 2.25" & 3.00" Blocks

These durable ball bearing blocks feature large-diameter free-rolling sheaves. Use on dinghies, beach cats, and iceboats as well as small off-shore racers and cruisers.
The 3.00 in (75mm) single block is available in high load configurations. The wire version features Hardkote-anodized, Teflon®- impregnated sheaves.

Harken Little Hexaratchet

The Little Hexaratchet® allows crew to hand-hold sheets with up to 10:1 holding power. These blocks feature an eight-sided sheave machined from solid aluminum for strength and corrosion resistance. Low friction Delrin® ball bearings allow fast trimming under high or low loads. The on/off switch operates easily under load.

The 043 reverse ratchet is paired with the 019. It is used on spinnaker and jib sheets where ratchets must rotate in opposite directions and on/off switches should face up.

Harken Hexaratchet II+2 (classic ratchet)

Harken® Hexaratchets® grip loaded sheets with up to 15:1 holding power, yet allow line to be eased instantly with complete control. Ratchets feature an eight-sided sheave machined from solid aluminum for strength and corrosion resistance. Low friction Delrin® ball bearings allow fast trimming under high or low loads. A switch turns off the ratchet in light air.

The 044 and 045 reverse ratchets are paired with the 009 and 050. They are used on spinnaker and jib sheets where ratchet rotation must be in opposite directions and on/off switches should face up.

Harken Dinghy Vang System

Harken Dinghy Vang comes revved with line for a powerful 15:1 system. Constructed with a 3:1 cascade inside a 5:1 purchase, the vang housing is tough stainless steel with lightening holes to minimize weight. The stainless steel mast bracket fits most masts.

Harken uses extremely small strong blocks to build this system: 16 mm AirBlocks® to handle high loads, and the Micro Carbo-Cam® for precise trim. The Carbo -Cam® pivots to keep a fair lead, so it's easy to cleat even if you're hiked out. It also angles up and down to accommodate mounting height. There is even a clevis pin to attach your cunningham. The Dinghy Vang comes with low-stretch polyester line. It has a maximum mast to boom distance of 30 in. (760mm). You can shorten the system by a simple line adjustment.

Harken Two-Speed Mainsheet Systems

Gross-trim/fine-tune mainsheet systems are easy to install and use. For fast trimming pull both tails of the mainsheet. For more power, pull one tail and the purchase doubles.
Two-speed mainsheet systems come in three configurations for boats from 22 ft to 39 ft (6.5 m to 11.8 m) with mains as large as 350 ft2 (32.4 m2).
