Monaro Marine Ltd.

The 257 is an evolution of our 255 model. Many hours of thought, design and discussions with customers went into this boat to create something we are quite proud of.

The dash has been completely redesigned to integrate the optional electronics display and vhf. With this design the pilot can focus better on the water without reaching far for buttons or taking your eyes too far from the waters ahead. Being that this dash is larger than its predessesor there is more room behind for wiring and fuse panels making it easier for servicing. Another great feature is the charcoal finished color, producing less glare.

We have taken the hard top from the 235 model but have incorporated a longer windshield and repositioned the hard top to achieve the same amount of space inside the pilothouse. The new hard top comes with an improved water tightness with it's wider stance and drip edge all around. The underside is a fibreglass molded finish for low maintenance and durability.

The stern has been reshaped to create an updated look, more freeboard for safety, and more floor space inside the cockpit. The back panel has been raised up to meet the top of the deck and extra padding has been added making the stern seating more comfortable.

Also in the stern area the swim grid has been redesigned to integrate it into the hull. Fibreglass extensions have been added to the hull forward of the swim grid in order to wrap the rub rail around the perimeter of the grid and forward into the hull.

Hull graphics have been redesigned to make this boat stand out from other models. The all new interior upholstery has been taylored to create a totally new and exciting look for a Monaro.
