The kanji 泊 is a phono-semantic compound (形声文字, keisei moji). The semantic component (meaning part) is 氵 (water, radical 85, 水, mizu). The phonetic component (sound part) is 白 (shiro, white). The original meaning was related to ships anchoring in a harbor. The presence of the water radical 氵 indicates its connection with water, while the 白 provided the sound. Over time, the meaning expanded to include the act of staying overnight in any place.
