Common Concerns Answered
Will the adhesive last in harsh marine conditions?
While the waterproof adhesive is designed for marine use, prolonged exposure to extreme conditions or UV may weaken its adhesion over time. Users seeking the most robust or permanent solutions for competitive racing might consider alternative telltale systems.
Are these telltales durable enough for racing?
The lightweight ripstop nylon construction offers good durability for performance indication. However, some racers prefer more permanent telltale solutions, and the adhesive's longevity can be a factor in extreme racing environments.
What if the adhesive fails after some use?
The adhesive locator discs provide a simple attachment method. While generally effective, users in exceptionally harsh conditions might find adhesive longevity to be a concern after extended UV exposure and prolonged use.
Frequently Asked Questions
How do Davis Air-Flow Tels improve sail trim?
These telltales visually indicate the direction of airflow across your sails, allowing you to make precise adjustments to sail shape and sheeting angle. Observing how the telltales stream indicates whether your sail is luffing or over-trimmed, enabling you to fine-tune for optimal performance.
Do I need to drill holes in my sails to install Air-Flow Tels?
No, drilling holes is not required. The Air-Flow Tels attach directly to the sail surface using waterproof adhesive locator discs, preserving the integrity of your sail.
What are Air-Flow Tels made of?
The Air-Flow Tels are constructed from lightweight ripstop nylon, chosen for its durability and ability to react to airflow.
How many Air-Flow Tels are included in a kit?
Each kit includes a set of 14 Air-Flow Tels, providing ample coverage for various sail surfaces.
How do I read the air flow indicators on the sails?
Instructions included with the kit detail how to interpret the telltale's stream direction. Generally, if the telltales stream aft, the airflow is good. If they flutter or point forward, adjustments to the sail trim are needed.
