    I’m wondering if the bulb’s shape creates some lift too? The hull itself looks like a flattened torpedo, the foredeck almost looks like the top leading edge of a wing.

    I'm going to guess the bulbs are there to accelerate the water and generate a low pressure region around the connection of the foils and the arm. With AM's low aspect foils, this region would likely be very draggy, and otherwise divert the flow outboard, reducing efficiency.

    Right or wrong.. these may be compensation for AM's foil concept, rather than a go-fast feature on their own.
