About Harken Trimming Systems

Backstay Adjuster Backstay adjusters allow racers and cruisers to adjust and control mastrake and headstay tension. Adjusting the backstay shapes the main to optimize upwind and downwind performance. On racer/cruisers, tightening the backstay increases headstay tension for upwind sailing, while loosening the backstay ofwind reduces weather helm. View all Backstay Systems

Boom Vangs The vangs allows vertical adjustment of the boom, and is an extremely important tool to shape the main for speed. Tension the vang to tighten the leech, flatten the sail and bend the mast. Cruisers use the vang to keep the boom from rising when sailing downwind and abraiding the main. View all Boom Vangs Systems

Cunninghams The cunningham controls the fore and aft position of draft in the mainsail or genoa and works together with the traveler, mainsheet, outhaul and vang to optimize sail shape and increase boatspeed. Cunningham controls lead to the crew to encourage adjustment as wind speed changes. View all Cunninghams Systems

Genoa Lead Cars These car change the sheeting angle of the genoa to keap the sail shape efficient. Excellent for racers, and cruisers with furling genoas. Pinstop and adjustable cars come in T-track and ball bearing track configurations. View all Genoa Lead Car Systems

Mainsail Reefing Mainsail reefing systems must operate efficiently to reduce sail under adverse conditions and provide proper sail shape when reefed. These systems are a must for both racers and cruisers. View all Mainsail Reefing Systems

Mainsheet The mainsheet is used to change the sail's angle of attack, leech tension, draft and shape. This system works with the traveler, vang, downhaul and outhaul to optimize sail shape. Two-Speed Mainsheets: These dual purpose system offer sailors the option of either speed or power. They are used for mainsheets on small to medium-sized offshore boats where power is required for effective heavy- air trimming and mark roundings. View all Mainsheet Systems

Mastbase Blocks & Cabin Tops Mastbase and cabin top blocks allow crew to raise, lower and trim sails from the cockpit. A variety of specialized blocks have envolved for routing lines aft. View all Mastbase Blocks

Outhaul Systems The outhaul controls and shapes the mainsail. Ease the outhaul to increase draft and power up the sail. Tighten the outhaul to flatten the sail and reduce drag and heel in heavy air. View all Outhaul Systems

Self Tacking Jibs Self-tacking jibs and satysails are popular on boats of all sizes because tacking is nearly automatic, with no need to haul or release a sheet. They work well with furling systems and with jibs booms. To calculate loading for traveler cars and blocks use the jib sheet formula. View all Self Tacking Jibs Systems

Spinnaker A well-designed system makes all the diference when setting, flying and jibing the spinnaker. Trimming involves three adjustments: raising or lowering the pole, moving the outboard end of the pole forward or aft, and pulling in or easing the sheet. View all Spinnaker Trimming Systems

Spinnaker Pole Handling Both racers and cruisers benefit from adjustable spinnaker polr cars. Racersuse adjustable cars to square the spinnaker pole's inboard end to the horizon and help with dip pole jibing. Cruisers use the car to level the whisker pole when sailing downwind wing-and- wing and to store the pole against the mast when not in use. View all Spinnaker Pole Handling Systems

Traveler Travelers let crew easily adjust a loaded car to position the boom and control the sail´s angle of attack. On smaller boats, controls are located so the helmsman makes adjustments. On larger boats controls are usually placed within reach of the mainsheet trimmer. View all Traveler Systems
