That's a great suggestion! Thanks for showing a pic too, that helps a lot.
On with an update then:
Now that my templates were done I needed to get on with making a mockup before I start cutting up expensive plywood and not quite getting it right. I'm reasonably picky about stuff fitting and all that and would like to get this right the first time. Here I have a picture of each piece cut out and ready to be put on a basic frame:
In the middle piece I've drawn out where the sink and stove will go and where the cooler will be. Hard to tell in such a small pic, but they're worked out on that piece. Each side piece is cut so that it matches the top in width and is the right height. Measure 5 times, cut once, even cheap plywood like that.
After building a basic frame with 1x2 I screwed each piece on and tossed the sink and stove in place to see how it would look:
Not bad I think. I'm looking forward to getting this down to the boat and seeing if it fits in the companion way for one, but then in place and up to the shape of the hull. I have to cut out the front part or I'll never see if the forward side fits right (that is if the hull side fits correctly). That will help the next item that I want to work on, which are the doors for the front to get under the stove and sink. I've managed to get some nice mahogany for that so I'm looking forward to get on with that.
Next major stuff is to do a thorough clean up of the hull, some fiberglassing to allow me to attach the new vinyl covered plywood and paint on top of all that with some kind of insulation that has yet to be decided on. Lots to do. I'll post more soon. Of course any pointers or suggestions are more than welcome.
