A 22-foot wooden clamboat we used for scalloping needed a new floor. Ended up rebuilding EVERYTHING but the sides, transom and nose. Rebuilt framing, floor, etc., etc. Did it working Tuesday evenings (see YouTube: http://www.youtube.com/watch?v=BYSFdFs0mkA) ...have photo (and video) documentation from out of the water-to rebuild-to back in the water and working. Ryobi tools used: Ryobi circular saw, Ryobi battery driver. I also own a Ryobi compound mitre saw and a Ryobi tablesaw.
