Right, but you are not carrying it around unfolded. I think that is the weight concern that I was responding too (monster envy)It does gain the weight of a normal vessel its size when unfolded, but I don't know what the normal weight of "a ship 24 feet long, 8 feet wide, and 6 feet deep with a deck, rowing seats, five sets of oars, a steering oar, an anchor, a deck cabin, and a mast with a square sail" is, beyond quite a lot. It doesn't match the dimensions of any vessel that's been statted in 5e, not that most of those vessels have listed weights in any case.
