Purchase Upgrade Kits (T32KIT and T32KIT.HL) upgrade from 1:1 to 4:1 and include: (4) blocks, (2) deadends, and fasteners

When deciding on a purchase system, expect the load on the control line to be approximately 20% of the load on the mainsheet block. For most cruising boats, this will mean designing a 4:1 (or even higher) purchase system to keep control line loads in the reasonable 30 to 45 lb range.

Harken purchase recommendations when using 32 mm traveler control blocks:
Use a 3:1 purchase for boats with sail area under 240 ft (22 m)
Use a 4:1 purchase for boats with sail area from 240 ft to 400 ft (22 m to 37 m)
Use a 6:1 purchase for boats with sail area from 400 ft to 550 ft (37 m to 51 m)
Use a 2:1 purchase led to a winch for boats with sail areas above 550 ft (51 m)
