Formerly the jack lines terminated at the forward beam; simple and strong, but cause a tripping hazard. After far to long a wait, after a suggestion by my daughter, we relocated them to the edge of the tram, where combined with a small back-up plate and the natural strength of the hull flange and trampoline track, there is a natural strong point.
The aft end is still anchored to the hard top railings, the spliced end of the dockline cow-hitched around a center point attachment, spreading the load.
The forward end is lashed (many passes of parachute cord adding up to a 5500-pound line) to a 316 SS bolt hanger. The chafe gear is for UV protection.
Less of a trip problem, equal access, easy to re-tension.
Why rope instead of webbing, as is the conventional wisdom? Though I've discussed this before...
And we use 2-arm tethers. One about 72" and the other about 30". Fit them to YOUR boat.
- UV. We leave them rigged 365 because we believe night comes every day, the water is cold in the winter, single-handers need to stay on the boat, and thunderstorms give little warning.
- Under foot? We don't worry about stepping on them because they do not run on the deck.
- Stretch. We like the stretch of nylon dock line because we have a cat and used long tethers. If we were a mono-hull we would use something lower (but not zero) stretch.

Although some of this is pretty specific to Drew's PDQ 32, this tip on Sail Delmarva could apply to any boat: Tripping hazards are what send people overboard - they should be eliminated if possible...
