The vessel also includes a self-draining outfall having a channel integral with the hull and in communication with the recessed portion, the channel extending from the recessed portion through an outer surface of the hull. The self-draining water outlet further comprises a blocking piece arranged in the channel and a flow plate facilitating the limiting of the blocking piece in the channel. 在一个示例中，一种船只，包括限定凹入部分的船体，所述船体是一体的单件式结构。所述船只还包括自排水的排水口，所述自排水的排水口具有与所述船体成一体并与所述凹入部分连通的通道，所述通道从所述凹入部分延伸穿过所述船体的外表面。所述自排水的排水口还包括设置在所述通道中的阻挡件以及有助于将所述阻挡件限制在所述通道中的流板。
