Harken Carbo Ratchamatic - T2 Soft-attach

Harken Ratchet Blocks help the crew to handle heavier loads, providing supreme handling for mainsheet and spinnaker systems on beachcats, dinghies and sportsboats.

Harken Sheaves:
Harken standard ratchamatic sheaves maintain a secure grip on the line by means of eight specially designed facets.
Facets are the angled concave shapes formed specifically to grip the line under load.
They act a bit like the pockets in a chain gypsy (although far less pronounced).
The faceted sheave allows a loaded sheet to be hand-held, yet still allow instant easing with control.
The crew can hand-hold main, jib, and spinnaker sheets with only a faction of the effort that a regular block requires.

Standard Holding Power - 10:1
Standard Holding Power sheaves are black anodised for identification:
Holding power varies according to sheave size and type.
40mm and 57 mm Ratchamatic blocks with eight-sided faceted sheaves can provide up to 10:1 holding power.

You can look at this in two different ways:

• The crew can withstand 10 times more load than on a normal block without the sail winning :-)
• The crew will only need 10% of the effort to withstand the same load on a normal block (10kg of force requires only 1kg holding power)

Harken Ratchamatic Block Design and Construction features:

• Super lightweight parts
• Composite fibre-reinforced sideplates
• Hardcoat anodised aluminium sheave
• Lightweight soft-attach method
• Minimal moving parts in the ratcheting mechanism

Harken T2 Carbo Ratchamatic Plus Factors:

• Lashing allows ratchet adjustment close to the deck
• Splicing with a large diameter line uses the tail to fasten the block at the height needed for a fairlead
• Pressure on the line engages the ratchet mechanism, which switches seamlessly from free running to ratchet mode
• Unloaded main and jib sheets run out freely during mark roundings and asymmetrical spinnaker sheets become free to run instantly during gybes
• T2 ratchamatic blocks are clearly labelled with high contrast directional markers for correct reeving and trimming direction
• A becket can be formed by passing the line through the mouth of the block and making two becket loops, detailed instructions come with the block
