Boat Brew is a Red/White tournament deck which offers lots of card advantage. It was originally introduced by Brian Kowal in a cruise qualifier. This deck became very popular after it was first introduced (especially at Pro Tour Kyoto 09).
Here is an original deck list that was played in 2008.
Knight of the White Orchid combines with Mind Stone to double accelerate (if on the draw) at turn 3.
The finisher is, without a doubt, Siege-Gang Commander. If unblocked, Siege-Gang Commander can deal 12 damage max that turn.
The recent version of Boat Brew offers more aggressive cards. Here is a look at Pro Tour Kyoto Top 8 decks.
