Machined hardkote-anodized aluminum sheaves: strength
and corrosion resistance.
Fast trim: Free-running ball bearings.
Hand-hold and release loaded line: Faceted aluminum sheave grips line
securely. Ratchets provide mechanical advantage.
Multi-faceted Power3 sheaves: very aggressive holding power.
B
Load-sensing ratchet block: rolls freely in both directions under low
loads and automatically engages ratchet as loads increase.
Ratchet engagement adjustable: adjustable to ratchet at higher/lower
load to match sailor's strength and sailing style.
Cam arm locking plates: Allows cam arms to be locked in more than
five positions for fair leads.
Cheek: Line-shedding, small mounting footprint and drain holes.
Mounts on port or starboard.
Common uses: Main/jib/spinnaker sheets on dinghies and sportboats;
control lines on boats of all sizes.

Using Ratchamatic® Block
Low load Sheave spins
either direction
Ratchamatic® blocks spin freely in both directions under low load. At higher load, ratchet engages, and sheave facets
provide holding power. As the load decreases, the ratchet shifts back into light air mode and free spins. Unloaded main
and jib sheets run out freely during mark roundings and asymmetrical spinnakers run free during jibes.
Ratchet direction:
sheave will spin in ratchet mode. Refer to arrow when
reeving block or mounting cheek block.
Remove becket to access ratchet
adjustment hole.

Holding Power
Ratchamatic blocks allow hand holding loaded sheets. The eight-sided faceted sheave grips loaded sheets yet
allows a line to be eased instantly with control. They allow the crew to hand hold main, jib, and spinnaker sheets
with only a faction of the effort that a regular block requires.
Holding power varies according to sheave size and type.
57 mm Ratchamatic blocks with eight-sided faceted sheaves can provide up to 10:1 holding power.
57 mm Power3 Ratchamatic blocks with added facets offer increased holding power. See chart below.
75 mm Ratchamatic blocks with eight-sided faceted sheaves can provide up to 15:1 holding power.
Holding power ratios are determined using a 180° wrap angle and can very according to line type, and line
condition.
Power3 Ratchamatic® Blocks - Holding Power
Power3 Ratchamatic® blocks offer three options of faceted holding power to best take advantage of the day’s wind
and wave conditions.
57/ 75 mm block no. Sheave color Holding power 57 / 75 * Sheave image and facet count**
2625 - 57 mm

*Holding power ratios are determined using a 180° wrap angle and can very according to line type, and line condition.
Depending on line composition and cover texture, the more aggressive sheave facets can increase line wear.
**The 2770 sheave has fewer facets than the 2168 and gains more holding power by having more prominent ridges.

with block before drilling. Remove block. Important—
holes are different diameter. Use two drill sizes for
deck holes. See chart and diagram. Bevel top of deck

3-Way U-Lock—2629 / 2630 / 2632 / 2634 / 2685 / 2686 / 2687
The 3-Way U-Lock on doubles and triples allows a change
of headpost direction from front-to-side or allows the block
to swivel. To change headpost direction, remove shackle, turn
post, install shackle. Remove U-Lock to allow block to swivel.
Adjust Cam Angle (Single/Triple)
1. Loosen cam arm locking plate screw and pull outward
to disengage.
2. Rotate cam arm to desired position.
3. Press locking plate in and tighten screw.
Do not overtighten screws or sheave will bind.

Inspect Block and Shackle Before You Sail
WARNING! Failure to inspect and replace damaged metal parts and/or worn or frayed line can cause
block or system to break causing an accident, damage to your vessel, personal injury or death. See
www.harken.com for additional safety information.
Frequently inspect shackles and shackle posts for signs of corrosion, cracks, or elongation. When replacing
shackles, use the correct Harken parts to maintain proper strength. Replace line as necessary, taking into
consideration the maximum size recommendation.
Maintenance
Flush block and attachments frequently with
detergent and fresh water. Clean bearings by
flushing areas shown while rotating sheave.
If block has cam cleat, flush balls in cam
cleats while rotating pawls.
Warranty
For additional safety, maintenance, and warranty information see www.harken.com or the Harken catalog.
