i use three 2X6 planks for the ridge poles on my 30 ' boat. they are supported by vertical 2X4 s . for the rafters i use schedule 40 1 &1/2" plastic pipe. i heat the center with a heat gun & press it on the garage floor with the edge of a short 2X6 to flatten it allow it to lay on the 2X6 s at the proper angle to rest on the lifelines. i make a step cut in the ends & heat & bend them down to grip the lifelines. i place them about two feet apart & pull the heavy tarp over the boat & tie it down. i have enough room under so i can go up on a ladder & get inside to do work. i sanded & varnished all the brightwork & painted the deck & cockpit last spring between rain showers while under the tarp with a fan to blow out the fumes.
Liberals are people who care about others. Freethinkers are not constrained by the myths of religion.
