The main reason for dumping ballast is to trailer the boat, and perhaps to save some fuel while motoring, though I suspect that most leave the ballast in whenever afloat.
That said, assuming you're discussing the hybrid M26M/X, for similar money you can get a real nice real sailboat on the used market that will be a many-times-better liveaboard boat that will also happen to sail reasonably well.
Our son bought a nice Ranger 29 for the approximate cost of the 50 Hp motor found on these boats...... I'd much sooner live on that.
