Birth of Mizuha

Our requirements for building Mizuha

  • As short as possible from waterline to cruise under low-girder bridges even with higher tide
  • Should have "Funa-sajiki" a front deck for wide-open view to feel high sky, breeze, and lights
  • Want comfortable facilities small riverboats usually don't have.  Such as restroom, galley, electricities, or audio. 
  • Mizuha's cabin "Funa-mizuya" should showcase sophisticated craftsmanship of Edo/Tokyo for guests to see, touch, and feel.

Key points for boat designing

みづはを造るにあたって、実現したかったこと
  • Approx. 2 meters high from waterline
  • Restrain rolling from backrushes by bigger boats at Sumida-gawa River and Tokyo Bay
  • Enough width for habitability
  • Smooth cruising capability even weight of all guests concentrate on front deck bench
  • Restroom, galley, air-conditioners are must
    →Dr. Nakao, President of Alpha Craft Co. realized our complex requirements

Key points for shipbuilder's selection

設計のポイント
  • Should be experienced in passenger boat building
  • Good at using wooden materials
  • Lead time
  • Doing careful work

Production lines were full at nearby shipbuilders in Miura Peninsula.  Some of them could offer good lead time but only have experiences in fishing boats.  We searched and seached, over and over, and finally found Okamura Marine Craft in western Izu Peninsula in Shizuoka Pref.

Shizuoka is not too far from Tokyo.  They were empathetic enough to listen to our wish.
