I'm not sure where you get the terms "cruiser", "sailor" and "fast yacht" from in this context.
Assuming you're talking about disc area ratio (DAR), i.e. expanded area of all blades divided by total area of propeller
A longer, narrower blade is, generally speaking, more efficient and sees less interference
from adjacent blades. That's a factor that pushes the designer
to choose a low DAR, i.e. fewer, narrower blades.
At the same time, you need sufficient blade area to prevent cavitation (vacuum bubbles forming on the trailing face). Long, narrow blades (low DAR) means reduced blade area, increasing the risk of cavitation. If you have a diameter constraint, as is usually the case, you are often forced to select a higher DAR, i.e. more blades and making them wider, so that the prop can transmit full power without cavitating.
