Design method of shallow-draft ship and ship

The invention discloses a design method of a shallow-draft ship and the ship. The method comprises the following steps that the draft and expected load tonnage of the ship in the preset load tonnage level are determined; according to multiple parameters of the mother type ship with the preset load tonnage level, the value ranges of the multiple preset parameters of the ship are limited; a plurality of parameter selection values of each preset parameter are selected from the value range of each preset parameter, and one parameter selection value of each preset parameter is selected to form a plurality of trial parameter sets; the displacement of the ship and the weight of an empty ship are calculated according to the multiple trial parameter sets, and according to the fact that the expected load ton is equal to the difference between the displacement and the weight of the empty ship, the trial parameter sets meeting the conditions are screened out of the multiple trial calculation parameter sets to form a para
