ABSTRACT:
A surf-boat for travelling or standing on choppy waters, such as may be encountered in gulfs, bays, surfs and beach fronts is provided, typically having three pontoons, three columns and two concentrically aligned decks; an upper deck and a lower deck, wherein the benefits over typical single hull and multi hull and other prior art pontoon configurations, lies in the fact that the pontoons of the present invention are designed to plow-through a wave such as may be encountered in waters described as "choppy" resulting in limited wave response of the entire boat and a much smoother and a less motion-response-to-waves ride by persons on the boat. Other equally important features are that the main surface for people to stand on the boat is flat and the craft may be used as a stable observation or camera platform for observing and recording of watersports and marine life, and as an offshore rest and first aid station for boaters and windsurfers. The craft is also a good fishing platform which has the advantage, over small boats, of elevating the fisherman's viewpoint of the water, so that the angle of light reflection from the water surface up to about one hundred yards away, is significantly less acute and therefor less glaring to the fisherman's eyes. This also permits a better view of the immediately surrounding area below the water's surface.
The surf-boat when assembled resembles a three legged oil well drilling platform with the exception that the legs or columns are configured so that their stance, that is the distance between any two pontoon centers, is greater than the distance from the top side of the upper platform to the water surface. The pontoons may be either ballasted or are fitted with sub surface hydro-foils or a combination of the two in order to minimize the craft's buoyancy and/or responsiveness to wave action. The craft may be motorized or not and may have an engine-well centrally located on said lower platform for added stability. The craft may be fitted with a foot operated propeller and a removable semi-rigid flat weather shade which is sturdy enough to allow a 350 pound person to stand on top and use it as a diving platform or elevated observation deck, or sail.
