3/2 Layout 43 Mainship Galley-Up


JoMallie is a very nicely maintained Mainship 430 Trawler located on the east coast of Florida. This is the PERFECT SOLIDLY BUILT LOOP BOAT for a couple! 


The 430 Trawler is a handsome and affordable aft cabin cruiser with very spacious accommodations and a good amount of power. Indeed the 430 is a trawler in appearance, but because of her modified-V planing-hull, she delivers higher speeds than her competitors but just as efficient at cruise. With her wide-beam, this is a very spacious boat inside and out, even with walk-arounds on both sides. 


She has been updated with three 16,000 BTU air conditioners with heat, a newer beverage refrigerator, a new custom 12-volt freezer under the Pilothouse Helm seat, custom Pantry, Stern camera, convection/microwave, Vizio TV in aft cabin, all overhead lighting replaced with LED, fans throughout all the cabins, newer generator engine exhaust and new electrical wiring for the generator. 


The owners are looking to move up to a bigger boat for their family.

Accommodations

JoMallie has the optional and much preferred three cabin layout with a large Master in the aft cabin with a Vacuflush En-Suite Head and separate shower. Dedicated JVC Model KD-SX749 Stereo with CD Player and Vizio flat screen television. You may exit the aft cabin to the Transom from the aft cabin as well. 


Up a few steps is the well-appointed Main Salon with table and seating for four on the port side, TCL Roku Smart television while the starboard side has a desk and storage for all the manuals and other materials for the operation of the boat. 


There are a couple of chairs on the starboard side aft of the double Helm seat. JoMallie is equipped with a Central Vacuum system with enough hose to vacuum each cabin. The Tramontina portable ice maker conveys as well.


The Salon flows into the port side Galley where you have a 3-burner electric cooktop, newer Greystone convection/microwave oven, new 1.4 cubic foot beverage fridge, Sub Zero refrigerator/freezer, plenty of storage and counter space. Natural light is abundant throughout the Salon and Galley area. 


PLUS, you have wing doors port side in the Galley and starboard side outboard of the Helm/Pilothouse. This is a HUGE feature if your plans take you around the Great Loop! 


A couple of steps down and forward is the hallway to the twin guest cabin on the port side and the VIP cabin directly forward. The VIP cabin has a KOSS Stereo system with CD player. To starboard is the Guest Head (Vacuflush) with separate Shower enclosure.


Access to mechanical equipment and the engine compartment is gained by lifting these steps up.

JoMallie is well equipped with electronics and safety gear at the Pilothouse helm and on the Flybridge. 


There are two Raymarine ES97 multifunction displays (MFD's), one at the inside Helm and one on the Flybridge.

The fire extinguishers are all new and the GlobalFix VF4 Category II EPIRB is mounted above the desk/Nav Station and is about two years old. There is a separate Battery Charger monitored by the Balmar Smart Gauges.
