While I've never been a proponent of buying a short boat and then trying to pile a huge amount of displacement on it, I also am not a proponent of pushing the displacement per person too high and 16,000 lbs per seaman is really an enormous amount of displacement per person.
We have owned Sirius which displaces 32,000 lbs give or take loaded for over 9 years. In that time we have sailed her at least 15,000 miles [most of which in the 2 1/2 years we were cruising]. While docking requires both of us on deck and being very aware of all the factors we have cruised with a crew of 2for 90% of those miles. If you have at least an electric halyard winch, good windlass, and oversize sheet winches there is no reason not to sail a bigger boat from a crew standpoint if you have the skills. All this conversation is moot if you can't afford the $$ that these boats cost. We truly appreciate the comfort the extra size brings and can't count the number of times we pulled into an anchorage either significantly ahead of boats that left with us or upon arrival and comparing notes of our experiences out there.. we thought it was great.. they were a little beat up.
