You'd also need to wait until conditions calmed down to even try.
This can be calculated, if the construction is wood laminate or foam core
there will be positive buyancy even if the ama is flooded. enough weight has to be attached to overcome the buoyancy of the ama skin and beams depending on their construction. There is no one answer for multihulls, each design has to be evaluated individually by the owner to work out your best options. Different designs handle differently as well and need their handling tailored to suit.
