Hello. The site for the boat CNC does not come up any more but guessing the machine was the yellow one..
I did not buy there plans but my design closely resembles that layout. I like it in particular because it makes of a simple long axis gantry drive design and also alows for part clamping anywhere around the paramiter with out having to worry about gantry collisions (like with ones that have the gantry support under the table)..
see thread: for pics
