The blocks punctured the keels. In once case the block went through the keel and the FRP fuel tank in the keel. I saw no ballast although there may have been some further aft.
My recommendation after repair was that a minumum of four blocks be used and that each block be several inches wider than the keel.
Idid drill holes for their own back and I ran into lead right before the prop I do not know how far forward it goes but apparently this thing was sitting right in the water or anyways.
Would still like to know if I need to lead in concrete the keel but I need a specific weight or some kind of spec to know if it's even necessary if that's the case that it's hollow up front.
They gouged a hole in the side and I can see that the sides are very thick and still Hollow mid-ship and fore.
