It sounds like you’re already sold on the wide body style. If that works for you, then that’s what is right for you.
As I usually do, I’ll offer a contrarian viewpoint. Having full walk-around, easily navigable (and covered) decks, with a single level from helm to cockpit, has become an absolute must-have for me. Especially as I age and become less limber. I've found that the times I most need to quickly get to a point on the boat, to handle a line or fend off from hitting something expensive or unforgivably hard, inevitably comes during turbulent sea or wind conditions as the boat is being tossed around. At times like that, here's nothing like the security of true bulwarks and hull around you to keep me from taking an unplanned swim.
But then I think about boats differently from most people. I think about worst case scenarios and want to be prepared for them. I don’t concern myself so much with the 95% of the time when things are easy and going well, tied up at the dock or at anchor, or underway in open water in good weather. I concern myself with the 5% of the time when things are tough. Trying to dock in a tight space with a fairway only a couple of feet longer than the boat. With unpredictable winds and currents throwing the boat around with impending impact with something either expensive (someone else’s boat) or hard and damaging (rocks, pilings, etc.). At times like that I want to be able to quickly, safely, easily get to any part of the boat. Or snotty sea states when the boat is being tossed around and something has gone wrong and I need to reach that part of the boat in a hurry.
It’s times like that when things can go pear-shaped in a hurry. There is never any upside to an ‘incident’ on the water. My own personal priority is to be prepared for those and minimize the chances of something unpleasant happening (to either myself, the Admiral, or my wallet).
So, for me the decision is easy. Wide walk around side decks or no deal. But then I also don’t have to be concerned with carrying any passengers other than my wife. In 25 years of boating with larger boats (out of 55 years of owning boats in total) we’ve never had more than one other couple on board at a time and that was only for short day trips, and literally have never had anyone spend the night on any of our boats. We’ve never entertained large parties on our boats and never held yoga classes on board, so never wanted for an extra few square feet of salon space.
Again totally my personal choice, but I err on the side of greater safety, access, and convenience over a living-room sized salon. It only takes a single incident of impacting something, or worse, because of being unable to reach a particular part of the boat in time to ruin your day for a long time. But that’s what works for us. YMMV.
