Common Concerns Answered
Is the 6mm line limit too restrictive for my needs?
The 6mm (1/4 inch) maximum line diameter is suitable for most halyards, control lines, and reefing lines on dinghies and small keelboats. For heavier-duty applications requiring larger diameter lines, consider blocks with a higher maximum line capacity.
Will the cam cleat wear quickly under high loads?
The cam cleat is designed for efficient line holding on typical loads experienced in its intended applications. While composite cleats may exhibit wear over extended periods of extreme load compared to metal alternatives, its design offers a significant advantage in weight and cost.
Is this block durable enough for frequent use?
Yes, the Carbo Air construction provides an excellent balance of strength and low weight, making it highly durable for regular sailing. Its robust design ensures reliable performance across a variety of marine conditions.
