RE: Zig Zag - DIVE!!!
I bought one also to use as a retrieve boat. I added a small Teacup hook to the rear so that I can easily attach a line and ball to it. I haven't had any problems with it nosing over, which it shouldn't do considering that normally the angle of the prop shouldn't allow this to happen. The only thing that I can think of is that somehow it has become nose heavy. One way to check for that is to add some weight to the transom area to see if that helps.
