Sailaway, first, appologies for not being able to read your last post in total. Even IF I conceed your tying tight point of reducig the load on lines, (I'm not) but if I did, you would still be over looking wave action. There will alway be wave action (tital area or not) if your boat cannot rise and fall with the waves you will be putting significant stress on all points of your mooring, line, cleats, chocks, etc... that I'm guessing will be roughly equivilent to the bouyance factor of your boat. (hopefully significant). This isn't even including the possiblity of boarding waves sinking your boat if she cannot rise and fall with the wave action.
