Hi I was wondering if there are any plans out there for these sharks. I am trying to rebuild one. My friend bought a shark that seemed to be in good shape. However much to our surprise the shark literally stared to come apart while we where sailing it on Lake Michigan. We took on so much water and nearly lost the rig. Also the plywood decking stared to crack. We somehow made it back. Now the plane is to restore it to seaworthy shape. Any help or advice would be helpful.
