Going backwards:( Some days suck. -- 254hrs

I finally got back to Tiki today and figure out what was going on with BH4 floor bearer not landing even with the keel backbone. I then checked BH3 and it also was off:( The answer is in these pictures...

BH3 area. There shouldn't be a 1/2" gap

Forward of BH3, end of keel sides.

Those hull gaps then cause this:(

Looking back, I had problems with building keel backbone a couple years ago. I couldn't understand the plans well enough to get the curve correct for the keel sides. I don't remember if I understood at the time but these sides are where the hull sides land so the curvature is important to allow the the hull top edges to be at the proper height above the keel backbone and the floor bearer to be at the correct height. I suspect this is my problem because when I pulled the port keel up on the bench and measured the six  distances found on the drawing, from the backbone top to the top of the keel sides only one or two were spot on. Then when I checked to see how fair the curve was...well it wasn't:(

So now it's a step back. Tomorrow I'm going to disassemble the starboard hull and free the keel backbone. Then measure, mark and draw a fair curve and add/subtract as needed to have a fair curve for the hull sides to land on.

All in all a pretty depressing day, but I've got a plan which I didn't have this morning and that's progress!
