      A 12m long catamaran would easily do 10 knots if well designed.
      To make it a racer it would have to be 8m wide, very lightweight and
      carrie lots of sail. 20 knots would not be uncommon for a boat like
      Obviously for cruising the (French) canals it can't be too wide.
      4M wide would be ok. Cruising weight is estimated as 3-4 tonnes.

      The point is I am not convinced that a cat is the best solution.
      Hence my question about an easily driven hull 12m long.

      The writing accompanying the Hawkeye sketch suggests the boat
      accelerates without any planing hump thanks to the box keel.
      The box keel can be looked upon as a long thin hull carrying most of
      the boats weight the sponsons add stability and offer extra load
      carrying capability.
      Something like that 12m long?
