Really nice job on the handrails, Jerry! They look easy to make...but it's not at all easy to get them right! and you did. I admit to buying them because I made them once for my Tartan 27.
In this picture, you can see the forward termination of the safety line in the cockpit near the bottom right of the photo. It's like a dog run.... Clip-in with your 6 ft. tether, and you can roam from the mast to the transom, and down below...while the shackle slides fore and aft along the 9 ft cockpit.
I've spent weeks at a time clipped into this type of arrangement in open ocean transits in all kinds of weather and you get accustomed to it; it becomes effortless. It's especially nice in the Commander cockpit...long, unobstructed, and on a small boat. Cheap and easy to install.
