Abstract
A water jet ski or boat that prevents weeds or grass from entering or clogging the intake grate area, is simple in construction and installation, operates automatically without operator intervention, and allows the craft to be beached and refloated without damaging the anticlogging elements or the craft. The craft includes one or more, preferably two or four, flexible rods mounted at the forward end of the intake grating and depending downward and preferably rearward. Growing or floating weeds or grass encountered during forward movement of the craft will be forced by the rods downward, rearward, and, in one alternate embodiment, outward. The rods do not interfere with the laminar water flow from any direction into the intake and are flexible enabling the craft to be stored, trailered, beached and pulled back from the beach as desired and without damage.
