What is claimed is: 1. A planing boat with an airbag system comprising: a boat body extending in a longitudinal direction of the planing boat; an engine mounted in the boat body; a steering handle bar disposed at an upper portion of the boat body; a meter panel disposed in front of the handle bar; a hood which covers a front half upper surface of the boat body in front of the meter panel; a frame extending along the longitudinal direction of the boat body at a bottom portion thereof; a support frame provided in a vicinity of a distal end portion of the frame so as to extend toward a lower surface of the hood; and an airbag system including at least one bag-shaped airbag body, a housing which accommodates the airbag body, a detector for detecting a collision of the boat, an expanding unit which inflates or blows up the airbag body at the time of collision of the boat, and a controller for controlling the detector and the inflation of the airbag body, the airbag system further including a first airbag body in the handle cover which is blown up from the handle bar to a rear side of the boat, and a second airbag body in the handle cover which is blown up toward a front side of a knee position. 2. The planing boat with an airbag system according to claim 1, wherein the first and second airbag bodies are activated such that, depending on a degree of the collision, only the airbag body disposed in the handle cover is blown up, both the airbag bodies are blown up at the same time, or the at least one bag-shaped airbag body disposed under the hood is blown up with a time lag relative to the airbag body disposed in the handle cover. 3. The planing boat according to claim 1, wherein a timing of blowing up the at least one bag-shaped airbag body disposed under the hood is delayed from a timing of blowing up the airbag body disposed in the handle cover, and the expanded and blown-up area of the airbag body disposed under the hood is set to be wider than that of the airbag body disposed in the handle cover. 4. The planing boat according to claim 1, wherein the at least one bag-shaped airbag body disposed under the hood is set to be contracted, after the blowing up thereof, at a time later than the contraction of the airbag body disposed in the handle cover, set to be hardly contracted, or set not to be contracted. 5. The planing boat according to claim 1, wherein the airbag body disposed in the handle cover has a size along the width of the boat body, which is set to be larger than the width of the handle bar and smaller than the width of the boat body, and the at least one bag-shaped airbag body disposed under the hood has a size which is set to be larger than the width of the boat body. 6. The planing boat according to claim 1, wherein the airbag system is mounted to the boat body to be detachable in a set with a portion of the boat body. 7. The small planing boat according to claim 1, wherein the detector is mounted to the boat body to be detachable in a set with a portion of the boat body. 8. The planing boat according to claim 1, wherein the detector is mounted to be integral with the housing. 9. The planing boat according to claim 1, wherein the airbag body is colored in a color other than blue and green or coated with a fluorescent paint. 10. The planing boat according to claim 1, wherein the engine is mounted in the boat body below the rider seat, auxiliary engine machinery including a fuel tank is disposed in front of the engine in the boat body, and the second airbag body is disposed in a space above the auxiliary engine machinery. 11. The planing boat according to claim 1, wherein the engine is a four-stroke-cycle engine. 12. The planing boat according to claim 1, wherein the frame has an end portion located between the collision detector and the housing disposed under the hood. 13. The planing boat according to claim 1, wherein the airbag system includes further airbag bodies which are disposed in the grips on both ends of the handle bar so as to be expanded and blown up along the width of the boat body. 14. The planing boat according to claim 1, wherein the airbag system includes still further airbag bodies which are disposed in broadsides of the boat body so as to be expanded and blown up upward along the width of the boat body to cover feet decks in a side view. 15. The planing boat according to claim 1, wherein the airbag system is switched "ON" or "OFF".
