Yes there are new designs that would give you the accommodation you want. And here is the BUT. You can design a
boat to do almost any one thing well or even a few things well but usually not everything. Many modern boats are designed for the
charter industry, they want a
boat with lots of accommodation for its length that feels much like living in a small apartment, they also want it to be easy for a relative
novice to handle. They don't expect it to be out in bad
weather and don't allow charterers to go to
remote location so don't need their boats to be independent. Makes good boats for marina hopping with an occasional night at
anchor and for sailing in sheltered waters. Performance under sail tends to be lackluster at best ut they are easy to handle. At the opposite end you have a boat designed for expedition sailing in
remote areas, think up the coast to Glacier bay. They need excellent sailing performance (if you are 500m from the nearest
fuel station you have to sail!) They emphasis reliable and fixable design for max independence. They will have a design to allows you to sail or
anchor in all expected conditions. They will have things like narrow sea berths not double beds, you cant sleep if you are constantly rolling across or out of
bed, lots of handholds and no big spaces to fall across,
gear will be chosen for sailing efficiency and
reliability and assumes significant skill by the crew. Get the idea?
So start by having a good honest think about what you want to do. Mostly have a comfortable apartment on the
water that can hop to the next marina if the
forecast looks OK or
head out for a month and explore desolation sound? Once you sort that out boat designs should start to make more sense, its like deciding if you want a truck, sports car or Jeep for your next vehicle.
