Agreed that these are almost antipodal design requirements, but there is also a category in the middle - described as either 'performance cruisers' or 'racer/cruisers' designed for either dual use, or for sailors like me who believe that speed combined with good use of modern forecasting techniques are safer at sea than a traditional slow heavy cruising boat. Basically, be comfortable enough to be livable, and fast enough to avoid the worst weather. The design tradeoffs in that category are really interesting IMO. See most X-yachts designs, some of the larger J boats (for monohulls) or Gunboat, HH, and Outremer in the multihull space
