57mm Carbo HTE ratchamatic blockSKU: HK2625HTEThe 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.
The spring on the HTE (high-threshold engage) version of the 57 mm Carbo Ratchamatic blocks was made stiffer to delay the point where the ratchet engages, allowing the block to run free more of the time. The ratchet function engages at higher loads to allow the old kite sheet to run free for crisper gybes.
Standard grip: medium/light air; 10:1 holding power. Learn MoreNow Only €123.25 €123.25 Regular Price €145.00

12:1 GP catamaran mainsheet systemSKU: HK2800Harken’s Grand-Prix mainsheet systems are critically important options for high-performance beachcats like the Nacra 17 or F18s. The high-efficiency blocks making up these systems feature insert-molded ceramic bearings that almost eliminate rolling resistance, greatly improving power transfer to the crew for easy, precise trimming. These compact blocks feature hardcoat-anodized sideplates that envelop composite sheaves for easy disassembly/reassembly. The system profile is the lowest on the market by far. High-performance fairing increases aerodynamic flow and protects the crew and blocks from impact damage. The lower block features a built-in cam arm that infinitely adjusts by loosening two (2) screws with a hex key. A single ratchet sheave in the bottom block ensures release is controlled and smooth. A snap shackle attaches the block to the boom. A swivel shackle attaches to the traveler.
Note: the GP mainsheet system is delivered as a 12:1 mainsheet system, but can be easily reconfigured as a 10:1 or an 11:1 to align with wind or crew preference. All necessary parts and reeving instructions are included. Line not included. Learn MoreNow Only €2,560.50 €2,560.50 Regular Price €2,845.00
