How much does the mast effect the picture when the radar is mounted on the
stern?
How big of a slice does the mast block when the radar is mounted to the
mast?
Dang that's two questions.

Depends. If you have a larger open array, not much, if any. If you have a
very small antenna, perhaps some. However, unless you are are on a
prefectly steady course (not likely), the shadow should not be an issue.
