Rear boat extensions for boats and boats having such are provided. Some embodiments of boats include a rear boat extension as an attachment to their transom. Other embodiments of boats include a rear boat extension as a stern end part of a single molded component which includes the hull of the boat. In either case, the rear boat extension has a smaller depth than an adjacent part of the boat's hull. In some embodiments, a rear boat extension may be tapered toward its rearward end. In some cases, a rear boat extension may include peripheral sidewalls and may be open or include an opening at its rearward end or between upper edges of its peripheral sidewalls. In yet other embodiments, a rear boat extension may not include peripheral sidewalls. In any case, a rear boat extension may additionally or alternatively include an opening or recess within its bottom surface.

The boat of claim 1, wherein the first portion comprises a lowermost part of the peripheral sidewall. 5. The boat of claim 1, wherein the peripheral sidewall extends the length of the rear boat extension. 6. The boat of claim 1, wherein the peripheral sidewall has a length less than a length of the rear boat extension. 7. The boat of claim 1, wherein the peripheral sidewall is one of two peripheral sidewalls making up opposing sides of the rear boat extension. 8. The boat of claim 1, wherein the plate is pivotally mounted to the transom between parts of the rear boat extension affixed to the transom, and wherein the plate extends rearwardly from the transom with its width less than a width of the transom. 9. The boat of claim 1, wherein the rear boat extension is one of two rear boat extensions attached to the transom and arranged on opposing port and starboard sides of the boat. 10. The boat of claim 9, further comprising actuators for independently moving the two rear boat extensions. 11. The boat of claim 7, wherein the bottom portion extends between the two peripheral sidewalls and comprises sloped or curved sections. 12. The boat of claim 11, wherein a bottom surface of the bottom portion of the rear boat extension comprises a contour substantially similar to a bottom surface contour of a hull of the boat at the transom. 13. The boat of claim 1, wherein a width of the rear boat extension is substantially the same as a width of the transom. 14. The boat of claim 1, wherein a length of the rear boat extension ranges between about 1 foot and about 5 feet. 15. The boat of claim 1, further comprising one or more actuators coupled between the transom and the rear boat extension, wherein the one or more actuators are configured for moving the rear boat extension up toward the transom and down away from the transom to thereby move the rear boat extension in and out of the water in which the boat resides. 16. The boat of claim 12, wherein the bottom surface of the bottom portion of the rear boat extension is substantially flush with the bottom surface contour of the hull at the transom, so that the rear boat extension serves to extend a running surface of the hull. 17.
