I like these three in particular:
#1) The Intricate Art of Living Afloat
by Claire Alcard. Written but revised the original is out-of-kilter on the medicines for certain however the information on provisioning, voyaging, chartering (we did it on our 40'er) and taking on crew (what not to do) -- well, it's a good read. And it's a penny on Amazon.
#2) Tricks of the Trades
by Bruce van Sant (yes, the information in this book is also within his Gentleman's Guide to Passages South however it's in a better format -- not scattered within the island trek) I'm still learning his treatise on weather. Fascinating.
#3) Why Didn't I Think of That?
Speaks more to sailboats but also has a lot of modifications and ideas a full-timer could use to make their boat more livable.
I've read the Nicholas book. It's not bad. Mueller writes a better one. Groen I believe offers a similar topic. Tom Neale writes a decent one -- I'd pick his after the initial three. I'm sure there are others.
