Motor-sailboats are typically heavier than a sailboat of the same overall size. They also tend to have smaller sails, but a considerably larger and more powerful engine. They tend to carry much more fuel
, but not necessarily more water. They tend to be a bit higher off the water, making them a bit more top-heavy. As a result, they tend to be slower and not point as well as cruising sailboats. Being higher has its pluses and minuses as well.
On the other hand, they motor at hull speed far longer (thanks to bigger fuel
tanks) and can be a bit more seakindly (thanks to their higher displacement and ballast). Since they have "displacement" hulls, they will not plane, and are not as fast as powerboats of the same size.
They tend to be quite roomy, and since the sails are usually smaller, they''re easier to sail singlehanded. However, in light winds, they tend to just float with no apparent forward motion. That usually means that if you plan to go somewhere, the big engine will be running most of the time.
These are just some general observations. There may be some exceptions, but overall, motorsailboats neither sail very well, nor motor very well. However, if you''re in no rush and like lots of room, and the sound of an engine running most of the time doesn''t bother you, then maybe a motorsailboat is right for you. ;^)
