Scuba diver and sailor here. Above a certain size, boats have watertight bulkheads and pumps to remove water, like fire hose levels of water. May I suggest a thermal lance? Works great underwater, cuts through metal better than a drill, and can cut a slice long enough to cut past multiple bulkheads.
