Harken 57mm Carbo Ratchamatic

Harken 57mm Carbo Ratchamatic

57mm sheave, 3/8" maximum line size. The Carbo Ratchamatic is a load-sensing ratchet block that rolls freely in both directions under low loads, and automatically engages the ratchet as loads increase. When changing gears, the over-center shifting between ratchet and light air modes is crisp and seamless. Unloaded main and jib sheets run out like greased lightning during mark roundings. Asymmetrical spinnakers that require the tough holding power of a ratchet, also free instantly to give you perfect, effortless jibes. And how about this terrific feature? With the simple twist of an allen wrench you can adjust ratchet engagement to a higher or lower load to suit your own muscle power or sailing style. Great for main and jib sheets; also asymmetric spinnakers.

The Carbo Ratchamatic is a load-sensing ratchet block that rolls freely in both directions under low loads, and automatically engages the ratchet as loads increase. Shifting between ratchet and light air modes is seamless. Unloaded main and jib sheets run out freely during mark roundings and asymmetrical spinnakers free instantly during jibes.

Ronstan Orbit Blocks - Series 40 Auto-Manual Ratchet

Ronstan Orbit Blocks - Series 40 Auto-Manual Ratchet

Bettering the world’s ultimate ratchet block is no mean feat, but that’s exactly what the Ronstan Series 40mm Orbit Block has done. A unique sheave design has 12 gripping faces that directly resist loaded line movement and provide up to 25:1 holding power, nearly double that of its nearest competitor! Available as autoratchet or manual. Sophisticated, sheave cross-hole geometry delivers superior rope wear performance and is lighter weight than its closest competitors. The machined alloy sheave and ingeniously simple mechanism ensure reliability and long life. Essential equipment when you want the most holding power you can get.

In Auto mode the ratchet mechanism engages automatically when load is applied to the block, but switches off when the load is released to allow the sheet to run out smoothly and freely. This is particularly beneficial for rapid sheeting out in bear-aways at the top mark and for tacking asymmetric spinnakers.

In Manual mode the ratchet mechanism can be switched on or off as required. This is still often the preferred feel for mainsheets by many top sailors. In the end manual or auto mode often comes down to personal feel preference. Try the block in both modes and make up your own mind – you really can’t go wrong.

Applications:
- Dinghy mainsheets on boats such as Optimist, Laser, 470’s and 49er.
- Sportsboat mainsheet systems using RF7 mainsheet swivel cleat unit.
- Spinnaker sheets on dinghies – especially modern asymmetric classes such as 29er, 49er, I14, etc.
- Sportsboat and small keel boat spinnaker sheets (lateral lead blocks).
- Control line applications on larger yachts.

Materials:
Sheave: Hard anodized Aluminum
Ball Bearings: High compression strength carbon black Acetal
Housing/Cheeks: Toughened, glass fibre reinforced Nylon
Rope Link: UV stabilised, multi-strand impregnated SK75 Dyneema®

Ronstan Orbit Blocks - Series 55, Auto-Manual Ratchet (RT)

Ronstan Orbit Blocks - Series 55, Auto-Manual Ratchet (RT)

Bettering the world’s ultimate ratchet block is no mean feat, but that’s exactly what the Ronstan Series 55mm Ratchet Orbit Block has done. It still provides the 20:1 holding power of its Series 60 predecessor, but due to the sophisticated sheave cross-hole geometry (Patent pending) it delivers superior rope wear performance, lighter weight and is the only ratchet block available that can be set in manual mode or full automatic engagement mode1 - all this for the price of a manual-only ratchet block. Control switches on both sides allow for port or starboard use in manual mode and the NC machined alloy sheave and ingeniously simple mechanism ensure reliability and long service life. Series 55 Ratchet Orbit blocks™ also come standard with all the Orbit Block™ hallmark features; Dyneema® rope link head, composite cleat arms and our composite C-Cleat. Essential equipment on racing dinghies and sportsboats, when you want the most holding power you can get.

In Auto mode the ratchet mechanism engages automatically when load is applied to the block, but switches off when the load is released to allow the sheet to run out smoothly and freely. This is particularly beneficial for rapid sheeting out in bear-aways at the top mark and for tacking asymmetric spinnakers.

In Manual mode the ratchet mechanism can be switched on or off as required. This is still often the preferred feel for mainsheets by many top sailors. In the end manual or auto mode often comes down to personal feel preference. Try the block in both modes and make up your own mind – you really can’t go wrong.

Applications:
- Dinghy mainsheets on boats such as Optimist, Laser, 470’s and 49er.
- Multi purchase catamaran mainsheet systems on boats to 8m (26ft) – RF56331.
- Sportsboat mainsheet systems using RF7 mainsheet swivel cleat unit.
- Spinnaker sheets on dinghies – especially modern asymmetric classes such as 29er, 49er, I14, etc.
- Sportsboat and small keel boat spinnaker sheets (lateral lead blocks).

Ronstan Orbit Blocks - Series 70, Auto Ratchet (RT)

Ronstan Orbit Blocks - Series 70, Auto Ratchet (RT)

The auto mode of the ratchet mechanism engages when load is applied, but switches off when it's released. This lets the sheet run out smoothly and freely-great for rapid easing of the sheet and for gybing asymmetric spinnakers. Quite simply, Ronstan Ratchet Series 70 Orbit Blocks™ have the highest holding power available. The sophisticated NC-machined sheave features Generation 2 of our patented sheave cross-hole geometry. Its holding power is up to 21:1, almost double that of our nearest competitior. The unique sheave design has 12 gripping faces which directly resist loaded line movement. The Dyneema® Link is easily fitted and is retained securely by a moulded retainer clip and the flexible link can be left with one end attached to the block when fitting - no more lost shackle pins.

Applications:
- Dinghy mainsheet systems - when maximum holding power is required.
- Mainsheet systems on sportsboats using RF7 mainsheet swivel cleat unit.
- Control line applications on larger yachts.
- Spinnaker sheets on sportsboats and small keel boats (lateral lead blocks).
- Spinnaker sheets on sports boats and small keel boats - especially modern asymmetric classes.

Materials:
Sheave: Hard anodised Aluminium.
Ball Bearings: High copression strength carbon block Acetal.
Frame/Cheeks: Toughened, glass fibre reinforced Nylon.
Rope/Link: UV stablised, multi-strand impregnated SK75 Dyneema.

Holt Allen 39mm and 52mmCarbon Autoratchets

Holt Allen 39mm and 52mmCarbon Autoratchets

These blocks have an ingenious load-sensitive mechanism that triggers the ratchet only when the sheet load increases. The transistion from ball race sheave to the tough holding power of the ratchet is incredibly smooth, providing the ultimate in hands free operation. Cheeks are made of glass filled nylon with stainless steel straps. Sheaves are of a carbon composite with Delrin ball bearings and stainless steel axles.

Selden 45mm Automatic Ratchet Blocks

Selden 45mm Automatic Ratchet Blocks

Selden ratchet blocks are designed for applications like dinghy main sheets and spinnaker sheets. The block makes it easy to advance your grip when hauling in the sheet and creates the perfect combination of control and convenience.

The technical features of the 45mm automatic ratchet block include Ø5mm Derlin ball bearings and Ø45mm aluminum sheave. The sheave automatically changes from free-turning to ratchet when the load increases. The sailor can decide when the ratchet kicks in. The switch over point is set using an allen key to adjust a screw inside of the sheave. The allen key will adjust the sensitivity of the automatic ratchet. A special insert is used to locate the shackle at 0 degrees or 90 degrees. When this insert is removed, the shackle spins freely.

When the block is set for a lower load, the ratchet mechanism is disengaged and the sheave spins free. Set for a high load, as the load on the block increases, the ratchet engages and the sheaves lock in one direction.

Harken Low Profile Triples

Harken Low Profile Triples

Low-Profile Triple ratchet systems are used on catamarans that carry booms close to the deck and for mainsheet and vang systems on offshore boats.

Rachets grip loaded sheets, yet allow line to be eased with complete control. They feature Hardkote-anodized, Teflon-impregnated eight sided sheaves machined from solid aluminum for strength and corrosion resistance, and free-rolling Delrin ball bearings. The sheave and sideplates are UV-stabilized for maximum protection and high-strength stainless steel straps reinforce the blocks.

The H152 is being phased out but is available by special order to replace parts in existing systems. Please consider a similar Carbo block for new systems.
