This patent describes a method for deploying a seismic subarray, which includes a float, seismic gun support beam and umbilical cable, from a vessel. It comprises: putting the vessel underway; connecting the subarray to the vessel by a detachable saddle rigged via a cable from a boom; moving the subarray along the length of the boom outboard of the vessel; deploying the seismic gun support beam from the float into the water, whereby the beam stabilizes the subarray; lowering the float to the water; releasing the detachable saddle from the float; towing the released float with the vessel by the umbilical cable; and raising the detached saddle.
