Spinlock TSR30 – 2 Sheave Organiser (Standard and Low Profile)
The Spinlock TSR30 2 Sheave Organiser is a heavy-duty aft organiser designed for diverting highly loaded lines from clutches and jammers to winches with maximum control and minimal friction. As part of Spinlock’s top-end TSR organiser family, the TSR30 is engineered around 30 mm alloy sheaves, providing increased bearing surface, improved deflection handling, and higher load acceptance than the TSR20 range. This makes it particularly suitable for larger yachts, high-load halyards, and control lines requiring significant changes in direction.
The TSR30 uses rotating alloy sheaves on plain bearings for predictable, reliable performance under extreme tension. The tulip-shaped sheave geometry reduces friction during vertical line deflection, while the modular alloy top rail allows full customisation of sheave spacing. Fixed sheave inserts can be added where even greater deflection loads are anticipated.
Two installation formats are available: the Standard TSR30 and the Low Profile TSR30L, the latter designed for restricted spaces such as mast bases, in-deck tunnels, or tight aft deck layouts where height must be minimised.
Key Features
• Two 30 mm alloy sheaves for handling high-load and large-diameter lines
• Designed for diverting lines from clutches and jammers
• All rotating sheaves run on plain bearings for reliable load handling
• Modular alloy top rail allows complete control over sheave spacing
• Tulip-shaped geometry reduces friction during vertical deflection
• Optional fixed sheave inserts increase permissible deflection loads
• Standard and Low Profile versions for installation flexibility
• Simple insertion and removal of endless lines
• Central load-distributing shaft for laminate protection
• Titanium components available for weight-critical installations
• Custom sheave spacing, mixed sheave diameters, and extended configurations available on request
Load Ratings – TSR30
• Maximum individual 30 mm sheave load: 2500 kg
• Total combined sheave load: 1250 kg × number of sheaves
• 30° deflected rope load: 5000 kg
• 60° deflected rope load: 2500 kg
These increased capacities make the TSR30 a preferred solution for diverting heavily loaded halyards, reefing lines, and code sail controls.
Applications on Sailing Yachts
The TSR30 2 Sheave Organiser is suited to yachts that require reliable diversion of very high-load lines, including:
• High-load halyards for mainsail, jib, staysail, and code sails
• Reefing, outhaul, cunningham, and tack line systems on larger yachts
• Situations requiring significant deflection angles or larger rope diameters
• Aft-deck and mast-base installations with limited vertical clearance (TSR30L)
• Performance yachts needing custom spacing or mixed-sheave configurations
• Clutch-to-winch routing where extreme loads or rope diameters exceed TSR20 capability
Compact yet extremely strong, the TSR30 2 Sheave Organiser is engineered for yachts that require precise, reliable diversion of the highest-load control lines.
