Yes, his stuff is very worthwhile - and I like most things by Contributing Editor Bob Lane (PNW owner of GB 42' "Quadra").I especially like the technical answers to reader's questions and the articles pertaining to boat problems and maintenance by Steve D'Antonio.
Even though I'm never going to buy a new (or even used) Nordhavn, Selene, or Fleming I still find value is seeing the solutions that designers have come up with - and maybe finding a DIY method for accomplishing something similar on my own boat (within my own budget <grin>).
The one magazine I really miss is "Powerboat Reports", the power analog of "Practical Sailor".
