Official abstract text for this publication.
A boat having a transom and a rear platform extending at least partially across the transom. The rear platform includes a hatch defining at least partially the rear platform, the hatch having a bottom surface, and a hatch pivot for pivoting the hatch about a hatch pivot axis from a first hatch position to a second hatch position. The boat is free of an enclosed engine compartment. The hatch at least partially defines thereunder a space for receiving a marine outboard engine. The space extends rearwardly of the transom and is open at a rear of the boat.

What is claimed is: 1. A boat comprising: a deck; a transom connected to the deck; a rear platform extending at least partially across the transom, the rear platform including: a hatch defining at least partially the rear platform, the hatch having a bottom surface; and a hatch pivot for pivoting the hatch about a hatch pivot axis from a first hatch position to a second hatch position; the rear platform and the deck being positioned substantially at the same height; the boat being free of an enclosed engine compartment, the hatch at least partially defining thereunder a space for receiving a marine outboard engine, the space extending rearwardly of the transom and being open at a rear of the boat. 2. The boat of claim 1 , wherein the boat has a beam, and the rear platform extends across a majority of the beam of the boat. 3. The boat of claim 1 , wherein the hatch has a front portion, and the hatch pivot is located in the front portion of the hatch. 4. The boat of claim 1 , wherein the rear platform has a front portion and a rear portion, and the hatch is pivotally connected to the front portion of the rear platform. 5. The boat of claim 1 , wherein, when the hatch is in the first hatch position, the hatch extends to a rear end of the rear platform. 6. The boat of claim 1 , wherein the hatch is further pivotable about the hatch pivot axis from the second hatch position to a third hatch position, the second hatch position being between the first and third hatch positions. 7. The boat of claim 6 , wherein the second hatch position and the third hatch position of the hatch are on opposite sides of a vertical plane containing the hatch pivot axis. 8. The boat of claim 6 , further comprising a lock for maintaining the hatch in the third hatch position. 9. The boat of claim 1 , wherein the rear platform and the hatch are structured to support at least 225 pounds.
