The invention discloses a vertical bow and front edge drainage combined damping structure used for a low speed full formed ship of which the ship speed is lower than 12 knots and a block coefficient (CB) is larger than 0.8. The structure comprises a ship body, a vertical bow is arranged at the head position of the ship body, the front end of the vertical bow is provided with a round hole, a rounded rectangle hole is formed in the tail of the ship body, the round hole and the rounded rectangle hole are communicated from front to back and are in smooth transition in the ship body to form a runner through which fluid passes. The invention innovatively puts forwards a concept of the vertical bow instead of a bulbous bow; further, a vertical bow technology and a front edge drainage technology are combined to effectively reduce wave-making resistance, and further reduce viscosity pressure resistance in a greater degree, and total resistance of the whole ship is reduced by more than 3%.
