I often see, from a distance or on the Net, sailors putting a board between two stanchions and tying diesel or water containers to them. I was wondering if anyone who does this could tell me if you just paint or epoxy coat a pine 2X4 or if you use teak or mahogany material. Also, it seems as if you are putting quite a load on the stanchions. How often do you expect to damage the lifelines doing this? I also have a sit-on-top kayak and have seen others with some bracket, again attached to the lifelines. Is this relatively safe also?
