Weird comment. Lookism isn't cool, even if targeted at horrible and powerful people like Elon Musk. ~~Also, how would more mass/larger surface slow anything down in space where there is no air resistance/drag??~~

More mass needs more energy to accelerate or decelerate. If you change the object's mass without changing thrust (I guess sail size here), it will definitely take more time to get there.

Ah OK, so mass is important but surface isn't, right?

In case of a solar sail however, surface is important.
