I see better on right side for sure but see decently well on the left side but increased speed means decrease in coverage and detail.
I am a little confused with this..... don't see why an increase in speed would make much difference..... Unless you are talking about approaching planing speeds.....
There has to be something happening otherwise IMHO ..... Motor torque changing hull roll (would have to be significant).... OR
Definitely makes one want to go out and try different scenarios..... slower... faster.... port...starboard.....trim up.... trim....
These anomalies are interesting in an engineering aspect BUT most of us don't really want to ponder such things.... we spent our money hoping that was all figured out 'beforehand'.....
