People are roughly* neutrally bouyant in water. Thus they don't weigh anything when submerged. Otherwise swimming would be very hard indeed. So you would need to weigh down the boat to sink all that air and wood.
*depending on depth and body composition, but give or take a bit, neutral.
- eric_h 11y agoAgreed, but boats when not filled with air are typically negatively buoyant. I'd wager that there's an air bubble small enough to make the whole system negatively buoyant, but large enough to sustain the people breathing it for some period of time.
