David Case has created a neat little web site covering "large projects"… various amateurs get themselves involved in large projects, such as home build airplanes and boats… he’s formed a site covering people’s projects and links to their web pages. He also hosts some Project Logs (Plogs as he calls them), where you can use his facilities to create a page to track your project.

He isn’t specifically about boats, but has a large boat section.

David’s section on "How To" for making a build log/project log had some valuable suggestions… check out the link for details.
