1. An apparatus for use in a marine geophysical survey comprising: rigid protracted geophysical equipment having a ratio of length to a largest dimension of width or height of about 1000:1 or more, wherein the rigid protracted geophysical equipment comprises control surfaces for controlling movement of the rigid protracted geophysical equipment when towed through a body of water; andwherein the rigid geophysical equipment comprises a plurality of rigid stems that are interconnected and each comprise a stem body defining one or more interior chambers, wherein the rigid stems each comprise a length of about 1.5 meters to about 50 meters. 2. The apparatus of claim 1, wherein the rigid protracted geophysical equipment is operable as at least one of: a lead-in coupling a streamer to a survey vessel, a streamer bearing a sensor, or a source cable for towing a geophysical source. 3. The apparatus of claim 1, wherein the rigid protracted geophysical equipment comprises an equipment section that comprises an outer covering and a plurality of spacers disposed in the outer covering, wherein the spacers are configured to align in a rigid line. 4. The apparatus of claim 1, wherein the control surfaces comprise at least one surface selected from the group consisting of a wing, an aileron, and a rudder. 5. The apparatus of claim 1, wherein the control surfaces comprise wings mounted to the rigid protracted geophysical equipment. 6. The apparatus of claim 5, wherein each of the wings is stowable in a corresponding wing cavity in the rigid protracted geophysical equipment, each of the wings being operable to extend from the corresponding wing cavity. 7. The apparatus of claim 6, wherein the rigid protracted geophysical equipment comprises sleeves that cover each wing cavity, the sleeves being slidably movable on the rigid protracted geophysical equipment. 8. The apparatus of claim 7, wherein one or more of the wings is configured to slide to different positions in the wing cavity to adjust control of wing angle, wherein the wing cavity is in the form of an angled groove. 9. The apparatus of claim 1, wherein the rigid protracted geophysical equipment has a maximum width of about 100 millimeters, a maximum height of about 100 millimeters, and a length of about 100 meters or longer. 10. The apparatus of claim 9, wherein the rigid protracted geophysical equipment has a length of from about 200 meters to about 16000 meters. 11. The apparatus of claim 1, wherein the rigid protracted geophysical equipment has an operational configuration with a bending stiffness of 700 Newton-square meters or greater over a distance of at least 25 meters. 12. The apparatus of claim 1, wherein the rigid protracted geophysical equipment is a sensor streamer that is not in the form of a cable. 13. A marine survey system, comprising: a survey vessel; andrigid protracted geophysical equipment being configured to be towed from the survey vessel, wherein the rigid protracted geophysical equipment has a length of from about 200 meters to about 16000 meters and a ratio of length to a largest dimension of width or height of about 1000:1 or more, and wherein the rigid protracted geophysical equipment comprises control surfaces for controlling movement of the rigid protracted geophysical equipment when towed from the survey vessel; andwherein the rigid geophysical equipment comprises a plurality of rigid stems that are interconnected and each comprise a stem body defining one or more interior chambers, wherein the rigid stems each comprise a length of about 1.5 meters to about 50 meters. 14. The system of claim 13, wherein the rigid protracted geophysical equipment is operable as at least one of: a lead-in coupling a streamer to the survey vessel, a streamer bearing a sensor, or a source cable for towing a geophysical source. 15. The system of claim 13, wherein the rigid protracted geophysical equipment comprises an equipment section that comprises an outer covering and a plurality of spacers disposed in the outer covering, wherein the spacers are operable to align in a rigid line. 16. The system of claim 13, wherein the control surfaces comprise wings mounted to the rigid protracted geophysical equipment. 17. The system of claim 16, wherein each of the wings is stowable in a corresponding wing cavity in the rigid protracted geophysical equipment, each of the wings being operable to extend from the corresponding wing cavity. 18. The system of claim 16, wherein the rigid protracted geophysical equipment has a maximum width of about 100 millimeters and a maximum height of about 100 millimeters. 19. The system of claim 16, wherein the rigid protracted geophysical equipment has an operational configuration with a bending stiffness of 700 Newton-square meters or greater over a distance of at least 25 meters. 20. The system of claim 13, wherein the rigid protracted geophysical equipment is a sensor streamer that is not in the form of a cable. 21. A geophysical survey method comprising: towing a rigid protracted geophysical equipment from a survey vessel in a body of water, wherein the rigid protracted geophysical equipment has a ratio of length to a largest dimension of width or height of about 1000:1 or more, wherein the rigid geophysical equipment comprises a plurality of rigid stems that are interconnected and each comprise a stem body defining one or more interior chambers wherein the rigid stems each comprise a length of about 1.5 meters to about 50 meters;controlling movement of the rigid protracted geophysical equipment using one or more control surfaces on the rigid protracted geophysical equipment; andeither (1) detecting a geophysical signal with a sensor towed by the survey vessel, and/or (2) activating a geophysical source that is towed by the survey vessel. 22. The method of claim 21, further comprising coupling a plurality of rigid stems end-to-end to form the rigid protracted geophysical equipment. 23. The method of claim 21, further comprising aligning a plurality of spacers in the rigid protracted geophysical equipment in a rigid line. 24. The method of claim 21, wherein the control surfaces comprises wings, the method further comprising deploying the wings to selectively position the rigid protracted geophysical equipment in the body of water. 25. The method of claim 24, wherein the deploying comprises opening sleeves on the rigid protracted geophysical equipment. 26. The method of claim 21, further comprising adjusting wing angle of a wing on the rigid protracted geophysical equipment by positioning the wing in an angled groove in the rigid protracted geophysical equipment. 27.
