Ditto. I,m still doing it after nearly 8 years. Partly because I didn't like some things and redid them, partly because I ran out of enthusiasm and once the unfinished boat was comfortable I preferred to go cruising.
The boat was (still is) full of timber. Nowhere to really store tools, sawdust gets everywhere and simply not enough space - and mines 57 foot and only me on it..
I would not do it again. Shoulfd I try it would be on hardstanding with somewhere else (nearby) to live. No distraction of cruising. More determination to finish and get going.
