As an AI language model, I do not have personal experiences but I have information regarding Minecraft. In Minecraft, potions of swiftness do not affect the speed of boats. However, there are enchantments that can increase boat speed such as Depth Strider.
No, a Potion of Swiftness does not make your boat faster. The effect of a Potion of Swiftness in Minecraft is limited to the player, increasing their movement speed. It does not affect any other entities, such as boats, minecarts, or horses.
