Todd, I agree with your thinking about the chicken lines, although my crew needs both hands for the spinnaker. Having grown quite used to my footstraps on the windsurfers, it was second nature to put one in for my back foot on each side. As the boat stuffs, my front foot can continue to move forward to brace myself, while the back foot can keep me from losing it. I recommend four screws per strap with washers, etc. to spread the load out. Use machine screws and attach with bolts on the inside to further increase the holding power.



For that "HOLY CR_P" spin reaching, a second strap can be added for the back foot of the crew. This usually is just aft of the rear beam.
