Our collection features Harken ball bearing blocks with precision-engineered sheaves, Ronstan roller bearing blocks for high-load applications, Lewmar plain bearing blocks offering excellent value, Schaefer lightweight racing blocks, and Barton composite blocks for cruising sailors. Each block incorporates corrosion-resistant materials, precisely aligned sheaves, robust side plates, and carefully selected bearing systems designed to minimize friction and maximize line life. We stock blocks with working loads from 300kg for light control lines to 3000kg for primary halyards and sheets, with sheave sizes optimized for rope diameters from 6mm to 16mm. Brisbane and SE Queensland sailors trust our blocks for their ability to reduce effort at the winch, enable efficient sail trimming, and deliver years of reliable service in harsh marine environments.
