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.

A water going craft comprising: (a) two generally triangular planer decks, being a lower deck, and an upper deck, each which have: top and under sides, leading and rear, port and starboard, sides and edges and leading and rear ends all respectively of an imaginary stem to stern centerline which extends from the center of the forward most part of the deck through the center of said rear edge of the decks being the rearward most part of the deck and an imaginary cross centerline which perpendicularly intersects and bisects the stem to stern centerline exactly midway between the front and rear ends of the decks and passes through the port and starboard edges of the decks the, said port and starboard sides of the craft being the portions of the craft to the left and right of said stem to stern centerline respectively, and wherein said triangular shaped decks are foreshortened whereby a flat front edge is created to be perpendicular to said stem to stern center line and port and starboard flat edges are created parallel to said stem to stern centerline; (b) a first forward and a second and third port and starboard pontoons respectively wherein said pontoons have a top, top central area, bottom, rear edge, inboard side, and outboard side, inboard top edge, outboard top edge, wherein said inboard and outboard references relate to the deck so that an “inboard”reference refers to a pontoon side or edge or place closest to the deck\s stem to stern centerline ,except for said forward pontoon wherein left and right designate inboard and outboard respectively; and (c) five legs, each having relative length, width, tops, bottoms and midway points between the tops and bottoms, they are; one forward leg comprising a hollow column and four aft legs; said four aft legs, comprise a port pair of legs and a starboard pair of legs; each pair comprises one inboard leg and one outboard leg, said inboard legs being approximately half the length of said outboard legs; and (d) one each port and starboard supporting struts; further comprising top and bottom ends, said struts are rigidly mounted to the rear edge of both said decks at a point between said decks\stem to stern centerline and extending from one to the other near the rear ends of said upper and lower decks respectively at or near said port and starboard flat edges, whereby when so mounted they support and hold the two decks apart; and (e) port and starboard stiff bars comprised each of a pair of stiffening bars, said port and starboard stiff bars each are used to stiffen and hold the pontoons at an outwardly extended position by being attached adjacent to the inboard leg bottom pontoon inboard edge attaching point and to a pivot point on said outboard leg between said outboard leg\s midway point and its bottom, said decks each further comprise three leg mounting areas: a forward leg mounting area, a port aft leg mounting area and a starboard aft leg mounting area, wherein further the each of the aft said mounting areas and said forward edge have means for attaching said forward leg to said forward leg mounting area, and means for connecting the top of said outboard legs to said underside of said upper deck aft leg mounting areas and said inboard legs to said underside of said lower deck aft leg mounting areas; and said upper deck leading end is attached to said forward leg between its midway point and the top of said forward leg and said said upper deck underside port and starboard aft mounting areas of said upper deck underside are attached to the tops of said outboard legs; and said lower deck is attached to said forward leg at a point on said forward leg from said forward leg\s midway point to its bottom and said lower deck\s aft leg mounting areas are attached to the tops of said inboard legs; said bottom of said forward leg is pivotally attached to the top central area of said forward pontoon, whereby said forward pontoon is steerable in a horizontal plane; and said starboard outboard leg bottom is mounted near said outboard top edge of said starboard pontoon; and said starboard inboard leg top being attached to said lower deck; said starboard inboard leg bottom is mounted near said inboard top edge of said starboard pontoon; said port aft leg mounting areas of said upper and lower decks are attached to the remaining said port inboard and port outboard legs and the port pontoon in a mirror image of said starboard aft leg mounting areas to said starboard pontoons via said inboard and outboard legs.
