Common Concerns Answered
Is the 'Carbo Air' construction as durable as traditional metal blocks for extreme high-load applications?
The Carbo Air construction is engineered for an exceptional strength-to-weight ratio, providing high working loads (440 kg / 970 lb for this 40mm block) suitable for its intended use on boats up to approximately 40 feet. While extreme offshore racing may benefit from higher load-rated blocks, the specifications demonstrate robust performance for its class.
Some users might prefer higher load ratings for extreme offshore racing. What is the limitation?
The maximum working load for this Harken block is 440 kg (970 lb), which is robust for most cruising and racing applications on boats up to 40 feet. For specialized offshore racing with exceptionally high loads, larger blocks or blocks with higher MWL might be considered.
How does the lightweight Carbo Air construction perform compared to traditional block materials?
Carbo Air blocks offer a significant advantage in weight reduction without compromising strength. This results in less inertia and improved handling of control lines, while maintaining high working loads suitable for demanding sail trim.
