I like that. Did you caulk the seam between the ply and the plastic tub? I also think that it is important to have secure storage for emergency equipment available in the cockpit so that you don't have to open the cabin in dicey conditions. I am just now finishing up a storage box for the stern of my 88' C 16 III which has no lazarette. I built a box that fits in the space at the stern of the cockpit where there is apparently a space for just such a unit or a larger gas can. My box is for wet storage of lines, gas cans, ditch bag, etc. I don't think that a person can have too much organized storage on a small boat.
