White boat, white robe,
After spending 17 years in the game (Reasonable Doubt dropped in 1996) Jay-Z gained quite a lot of money which with he can afford boats, cars, jewels…Everything really!.
When Hova’s aboard he always wears white shoes, matching all white everything clothes and a white boat.
This line also introduces the theme of duality between holy and material in the song, the contrast here lies between the white boat, borne out of material wealth, and the white robe, which is often seen as a symbol of spirituality and purity.
Also a veiled reference to cocaine being shipped on boats. That’s how he got his start to success (the prominence of the color white here plays on previous line, as cocaine is obviously white).
