Abstract
Ventilated sponsons, personal watercraft having ventilated sponsons, and methods for adjusting the handling characteristics of personal watercraft by ventilating the sponsons. The present invention provides ventilated sponsons, sponsons, having holes formed through the sponsons to allow high pressure water trapped under the sponson to escape. The holes formed through the sponson thus allow for fine tuning and adjusting the performance characteristics and handling characteristics of the personal watercraft long after the point of manufacture. Ventilating the sponsons can increase straight line stability while maintaining tight cornering characteristics.
