Benefits of technology

"The present invention relates to a watercraft with a deck and hull that has a stepped surface with sound suppressing dimples profiled to cancel out acoustic waves. The watercraft may also have a longitudinally extending turning fin and a rear chine portion. The sound suppressing dimples may be concave or inverted concave frusto-conical sections. The technical effect of this invention is to reduce the noise and vibration of the watercraft, making it quieter and more stable in water."

Problems solved by technology

Watercraft hull design is a complicated technology as multiple objectives are trying to be met at the same time.
While this acoustical chamber is not detrimental to the performance of the watercraft in use, it has however, increased to the point of being an annoyance to the driver and the passengers.

Embodiment Construction

[0025] With reference first to FIGS. 1 through 5, the general details of the watercraft will be described herein. With reference first to FIG. 1, the watercraft is shown generally at 2 and includes a deck portion 4 attached to a vessel hull 6. It should be understood that these two units are typically constructed in separate halves and then joined together along a central seam. It should also be noted that these decks and hulls are typically molded, or made from fiberglass about a mold, however the actual construction is not material to the invention. The watercraft 2 further includes an aft portion 8 and a bow portion 10, and as shown in FIG. 3 includes a port side 12 and a starboard side 14.

[0026] With reference now to FIGS. 2, 4 and 5, the vessel hull 6 further comprises a V shaped bottom portion 16, and port side and starboard side chines 18 which includes a forward chine surface 20 (FIG. 5) and a rearward chine surface 22 (FIG. 22). Primary strake portions 24 also flank second...

Abstract

A watercraft is disclosed, comprising a deck and a hull. where the hull is stepped intermediate a length of the hull to form an upper stepped surface. The upper stepped surface comprises sound suppressing dimples profiled to cancel an acoustical wave standing in the area adjacent the upper stepped surface. The watercraft has a longitudinally extending turning fin positioned adjacent to the upper stepped surface. The sound suppressing dimples are configured as inverted concave frusto-conical sections.

Description

[0001] This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60 / 709,877 filed Aug. 19, 2005, the complete disclosure of which is hereby expressly incorporated by reference.FIELD OF THE INVENTION [0002] The subject of the invention relates to watercraft, particularly of the type including molded and or fiberglass hulls. BACKGROUND OF THE INVENTION [0003] Watercraft hull design is a complicated technology as multiple objectives are trying to be met at the same time. On one hand, it is desirable for the vessel to be able to cut through choppy water and other vessels' wakes, and at the same time, it is desirable for the subject watercraft to not create a significant wake in the event that it is pulling water-skiers. It is also desirable to provide an efficiency to the hull design such that the boat easily planes over the water rather than cuts through it. For this reason stepped hulls have become popular in the vessel hull designs which provide an aerodynam...
