"sailboat" by 3D_LabteK with added keel extension

This is a the sailboat by 3D_LabteK, published Aug 11, 2013 http://www.thingiverse.com/thing:131439, with an added keel extension. The boat printed perfect, best print I've made. When I put it in the pool for my kids to play, it turned over. I used the existing keel to create a add on, slip over keel with front and back bull nose covers. The keel extension was slipped over the existing keel and the bull nose covers were super glued to the extension. The extension made the boat quite stable
