Mark...
Thank you for your continued assistance.
There is no magic number for the height...depends on what boat one owns at the time. I'd guess the cord should be raised a bare minimum of 2 feet...the more the better!
Braces in the upper corners might be a problem. On the plus side: I'd guess the biggest boat likely to be used in a 14 foot slip would have a beam of 12 feet or so. Also, it would not be uncommon for the upper part of a boat to be narrower than it's beam. On the minus side: Boats move, pitch and roll with wind/currents/wakes...
Nothing good oould come from a boat making contact with a timber frame! YEEKS!
