           | 
           | Boat pricing comes in a spectrum that very roughly looks like
           | this:
           | 
           | 3. PS20-PS40K Narrowboats are thirty or more years old, or
           | are under 50ft. They have had many owners each of which will
           | have done something to the boat. The engine fittings will be
           | old eg. coolant hoses , the radiators might not work, the
           | fireplace might need replacing, there is rust in important
           | places needing welding and so on. There may be overplating on
           | the hull to repair holes. In general, you can expect to
           | perform regular/constant maintenance and repairs to maintain
           | and keep them in working order. (some people enjoy this, you
           | may not)
           | 
           | 4. In the 40-60K range expect the boat to be about 20 years
           | old. Generally modern and most things will be working but it
           | might not have a good electrical system for modern
           | lifestyles. It will have 20 years of wear and tear, and the
           | interior might feel old and outdated.
           | 
           | 5. In the PS100k-PS120 range you should see 5-10 year old
           | boats. It probably will have a modern toilet/shower, modern
           | electrical maybe a solar panel, a nicer kitchen and modern
           | diesel engine/gearbox and propeller.
           | 
           | 6. At PS160K-180K you can get a new but simple/basic boat
           | fitout probably no solar, no dinette, few cupboards. Or it's
           | a five year old custom build that has been fully fitted with
           | many extras e.g washing machines, quality inverter/batteries
           | 
           | 7. At PS200K+ it a brand new boat, built to your
           | specification. An all electric boutique boat is PS220K-240K.
           | I've heard of narrowboats up to PS280K. Luxury wide beams
           | over PS350K do exist.
