Adding tactile cues to help a beginning sailor can be as simple as…
Textured lines. Labels that identify lines while hanging on the cuddy are fine. But at some point, those lines will be in the cockpit. Just as sighted sailors use color to quickly identify lines, various textures can help sailors who are visually impaired. Depending on the boat, it may not be necessary to purchase all-new lines. Try splicing the textured line onto the existing line – you could find you only need to add new lines for the last few feet.
Clutches and cleats. Consider opportunities to replace a cleat with a clutch. Then add textured material to the clutch arms to help distinguish each.
