I can't think of anything in boat-repair much more difficult than patching a hole with plate steel. It looks simple enough to an onlooker, but I've seen even professional welders (cheap ones, I might add) stuff it up totally by not allowing for weld stress and heating.


EDIT: Thinking about this, in theory you might be able to cut wood with a plasma cutter. Dunno.. I'm not silly enough to try it. It's always easier to use the right tools for the job at hand.
Use rounded corners on any patches. Weld the rounded corners last . The rest, weld an inch, let it cool, then weld another inch , etc. This lets the welds cool, and shrink as far as they are going to, before closing the circle.
