Got an email from Kay referring to her and her husband Doug’s web site where they are chronicling the home build of their personal submarine. Not something that everybody (even boatbuilders) will choose to bite off.
They also have details on a ROV (underwater Remote Operated Vehicle) that they provide plans for building your own.
Their next project is going to be a home build Origami (steel) sail boat.
Lot’s of details and things they are willing to share and help teach you via their postings. Really neat site that I can tell I’m going to enjoy.
