1. Apparatus comprising:a flat or wedge-shaped plate attached to a barge or other vessel having a substantially flat front surface, the plate being attached such that the plate, when the vessel is underway, is partially above and partially below the waterline and is forward of the vessel when the vessel is moving forward, wherein the plate has a front which is set a distance forward of the front of the vessel to minimize eddies. 2. The apparatus of claim 1, wherein the plate has a width which is 70-120% of the width of the vessel. 3. The apparatus of claim 1, wherein the plate has a depth, when the vessel is underway, which is 10-60% of the draft of the vessel when the vessel is underway, taken from water surface. 4. The apparatus of claim 1, wherein the vessel is an armored personnel carrier. 5. The apparatus of claim 1, wherein the plate has a width which is 90-1 10% of the width of the vessel. 6. Apparatus comprising:a plate attached to a barge or other vessel having a substantially flat, front surface, the plate being attached such that the plate, when the vessel is underway, is partially above and partially below the waterline and is forward of the vessel when the vessel is moving forward, wherein the plate has a front which is set a distance forward of the front of the vessel to minimize eddies. 7. The apparatus of claim 6, wherein the vessel has a width and the plate has a width which is 70-130% of the width of the vessel. 8. The apparatus of claim 6, wherein the vessel has a width and the plate has a width which is 80-120% of the width of the vessel. 9. The apparatus of claim 6, wherein the vessel has a width and the plate has a width which is 90-110% of the width of the vessel. 10. The apparatus of claim 6, wherein the vessel has a depth when underway and the plate has a depth, when the vessel is underway, which is 10-60% of the depth of the vessel when the vessel is underway, taken from water surface. 11. The apparatus of claim 6, wherein the vessel has a depth when underway and the plate has a depth, when the vessel is underway, which is 15-45% of the depth of the vessel when the vessel is underway, taken from water surface. 12. The apparatus of claim 6, wherein the vessel has a depth when underway and the plate has a depth, when the vessel is underway, which is 10-30% of the depth of the vessel when the vessel is underway, taken from water surface. 13. The apparatus of claim 6, wherein the vessel has a hull having a thickness and the plate has a thickness which is 70-130% of the thickness of the hull of the vessel. 14. The apparatus of claim 6, wherein the vessel has a hull having a thickness and the plate has a thickness which is 80-120% of the thickness of the hull of the vessel. 15. The apparatus of claim 6, wherein the vessel has a hull having a thickness and the plate has a thickness which is 90-110% of the thickness of the hull of the vessel. 16. The apparatus of claim 6, wherein the vessel is an armored personnel carrier. 17. The apparatus of claim 6, wherein the vessel has a depth when underway and when the vessel is underway the plate extends a distance above the water surface approximately equal to the depth of the vessel when the vessel is underway, taken from water surface. 18. Apparatus comprising:a plate attached to a barge or other vessel having a substantially flat, blunt front surface, the plate being attached such that the plate, when the vessel is underway, is partially above and partially below the waterline and is forward of the vessel when the vessel is moving forward, wherein the plate has a front which is set a distance forward of the front of the vessel to minimize eddies. 19. The apparatus of claim 6, wherein the plate is rigidly attached to the vessel. 20. The apparatus of claim 6, wherein the vessel has a depth when underway and the plate front is set a distance forward of the front of the vessel equal to about 70-130% of the depth of the vessel when the vessel is underway, taken from w ater surface. 21. The apparatus of claim 6, wherein the vessel has a depth when underway and the plate front is set a distance forward of the front of the vessel equal to about 80-120% of the depth of the vessel when the vessel is underway, taken from water surface. 22. The apparatus of claim 6, wherein the vessel has a depth when underway and the plate front is set a distance forward of the front of the vessel equal to about 90-110% of the depth of the vessel when the vessel is underway, taken from water surface. 23. The apparatus of claim 6, wherein the vessel has a depth when underway and the plate front is set a distance forward of the front of the vessel approximately equal to the depth of the vessel when the vessel is underway, taken from water surface. 24. The apparatus of claim 6, wherein the plate front is set a distance forward of the front of the vessel equal to about 8-20% of the width of the vessel or 60-120% depth of the vessel when underway. 25. Apparatus comprising:a plate attached to a barge or other vessel having a substantially flat, blunt front surface, the plate being attached such that the plate, when the vessel is underway, is partially above and partially below the waterline and is forward of the vessel when the vessel is moving forward, with a bow modified by circular cutaways at the comers to reduce side eddies. 26. The apparatus of claim 6, wherein the plate has a gap to the bow which is 8-20% of the vessel width and/or 60-120% of the vessel draft when the vessel is underway. 27. The apparatus of claim 6, wherein the vessel has a depth when underway and the plate has a forward offset, when the vessel is underway, which is 8-20% of the vessel width and/or 60-120% of the vessel draft when underway.
