[QUOTE="bassboy1, post: 170650, member: 55"] You weighed it with 1 x 1 x .125. Try a larger tube, say 1.5 x 1.5 x .125, or 1 x 2 x .125. Now, you aren't comparing apples to apples, as even though the larger tube is heavier, a deck can often be built with larger spans, and overall, less weight. On some deck layouts, on some boats, it is where the weight gains will be. However, on other deck layouts, and with some boat hull designs, it isn't practical, which is why we go back to the 1 x 1. One more thing to look at is 1 x 1 x .063. You definitely can save some weight there. For the boats I work on, the aluminum is used primarily for the longevity, and for lack of maintenance needs. I never have to worry about a cover not working properly, that is, if I even bother covering it, and rain, leaves, etc left in the boat during storage are no real issue. Aluminum will never warp as it gets wet and dries out, and won't develop soft spots. Pretty much the same reasons as choosing an aluminum jon boat over the equivalent plywood boat. More to do with durability than weight. [/QUOTE]
