This is hard for me to admit but I was to lazy to build a weekender, so I bought one already to go(now will you elect me president?) anyhoo, the boat has only one side-stay, and several outings in different kinds of weather,without any bad experiences YET. the builder said he thought it was overkill with two but I may add another one later. The boat creaks like an old ship when I change tack, once you tighten down the turnbuckles the mast seems pretty solid. I might also mention that this is a cabinless weekender,much easier to solo,lots of room, and also maintains a low center of gravity.
