Can someone please discribe the construction of Hunter ballast tanks on their water ballasted boats? While draining my H26's ballast tank, an irregular shaped silver dollar-sized flat piece of white rigid plastic came out of my drain. Could this be part of a liner for my ballast, or did I likely just suck it into my ballast tank when I last filled it? I'm planning on launching in the next few days and this has been worrying me. Thanks for any thoughts. BrianW
