Monaro Marine Ltd.

After many years of offering the popular Monaro 24' there became a need for a slightly longer boat. We were asked to design and build a model with more cockpit space and load carrying capacity - therefore the Monaro 255 was born. Optionally powered with either twin 4 stroke outboards or gas or diesel stern drive, it has become a winner of a design. Being able to plane level at very low speeds, yet obtain optimum high speeds has really impressed the owners of the 255's. The recent redesigned galley, dinette and aft deck area has already caught the attention of many other power boaters.
