Based on the highly successful Generation II M43 Sportfisher, the new Gen III Mikelson 45 boasts many of the same highly refined design features and so much more. Built for both durability and performance and constructed using BTI and Hexcell fiberglass materials, the new Gen III M45 features a solid fiberglass hull below the waterline and a Corecell foam core above, ensuring a boat that can handle the rigors of long-range cruising and sportfishing while keeping all onboard extremely comfortable.
The exterior boasts beautiful polished white gel coat and frameless windows, complemented by stainless steel deck hardware and a non-skid molded fiberglass foredeck. Powered by twin Cummins QSB 6.7L 550HP turbo diesel engines, the Mikelson 45 offers impressive speed and efficiency. Its advanced mechanical systems include a 9KW generator, comprehensive sound insulation in the engine room for quieter operation, and a 27,000 BTU air conditioning system for maximized comfort.
With its massive flybridge and creature comforts that are second to none, this new addition to the Mikelson line-up is designed to deliver a superior boating experience, making it the perfect choice for those who seek a blend of comfort and performance while on the water.
