Optimize your sailing performance with quality marine blocks from Bosun's Locker. Our range includes single and multiple sheave blocks, snatch blocks, cheek blocks, and specialized rigging blocks designed for smooth line handling and reliable load transfer. Sailors throughout the Gold Coast rely on our block systems for efficient sail control, reduced friction, and improved mechanical advantage in every sailing condition.
What's the difference between ball bearing and plain bearing blocks?
Ball bearing blocks offer lower friction for racing and frequent trimming. Plain bearing blocks provide excellent durability and value for cruising applications.
How do I calculate the working load needed for my blocks?
Multiply maximum line load by safety factor of 4-5. Primary halyards need blocks rated 5-10 times sheet loads depending on purchase systems.
When should I use a snatch block instead of a fixed block?
Snatch blocks excel for temporary rigging changes, spinnaker sheets, preventers, and any application requiring quick line insertion without threading through the sheave.
Do sailing blocks need regular maintenance on the Gold Coast?
Rinse with fresh water after use, inspect sheaves and side plates for wear quarterly, flush bearings annually, and replace blocks showing cracks or deformation.
