Hi KatheK
Below is a list I made after chartering a 390 and purchasing our 400. It may be of some help. We've been very happy with the 400 after 5 years, loop and 9,000 miles. Happy to try and answer and specific questions. Paul
Mainship 400 Pro’s and Con’s
Pro’s:
Great walk around has been a big help for locking and docking
Ergonomics generally very good, i.e. stairs, getting on and off
Tons of upstairs and outdoor living space and bike storage
Airy main level with 360 degree views for the chef and all
Great galley and storage, electric stove / oven works well
Large head and shower
Extremely well done electrical and mechanical systems
Fixed? Issues with the 340/350/390
- forward birth bulkhead is higher and shallower so you don’t bump your head turning over at night
- no well by the helm door to trip you
- has a dinette table for 4
Con’s:
Small sleep cabins have no lounge space to do double duty
240 volt isolation transformer means no power at all if no access to 240 volts at docks or boat yards and problems at 208 volt docks
Unfolding the salon hide a bed a problem
Bow master V birth is noisy due to wave slapping on hard chine,
All boats with hard chines have the same issue to some degree?
Cummins a great engine and extensive service network but electronic engine management means not much user service can be done ( mechanical Yanmar might be the better choice if you are used to doing a lot of your own work.) Getting down in to the engine compartment is awkward with the single but great access once in.
Electric vs. propane for stoves and BBQ
Not good (I don’t think many power boats are) in heavy or rolly seas compared to a sailboat
Horrible generator access for coolant change
Low pilot seats
Expensive relative to the 390
Narrow cabin due to the wide walk-arounds not very conversational?
