Like I said, daydreaming.
A boat that ticks a whole lot of the boxes is the Herreschoff H28, a design that's stood the test of time and is much beloved by those who build and sail them.
As it's quite an old design, some of the plan details are actually available on the web. Most notably the offsets, which detail the shape of the hull in three dimensions. I've spent some time over the last couple of weeks transcribing the offsets onto the computer, converting them to metric, and then using sketchup to loft a 3D model from them. Here's a few views of my model thus far. As with Elena, I hope to use this model to try things out, like interior accommodations etc.
