At the end of the dual lines, the two primary components are finally ready to be mated. Once again, a robot demotes me to observer as it meters out the precise amount of adhesive along the hull’s bond line. I then step in, along with a fellow worker, to guide the now-flipped deck down and atop the hull. It fits like the lid of a shoe box, with the deck flange overlapping and mating against the hull flange below. A heated cure oven will finish the job for a lasting, watertight seal. My day’s far from done. I also glue down the traction mats, bolt on the handlebars, and add the rub rail and colored insert along the bond line. Ultimately, my craft rolls off the line, down a short ramp, and gently splashes into a water-filled test tank, where robot arms push it down at various angles to test for water intrusion.
