Dave is at the top of his game in creating high-quality accurate plans for water vessels of all types. No one knows special application hydraulics better. We have worked with him on several of our projects and have been pleased with the quality and timeliness of his performance. I have also worked with him in the Genesis 3 Society of Watershape (SWD) educational program where he is one of our top instructors. I highly recommend David and his company, Watershape Consulting.
