Curious what people think. I can't be objective because I'm so used to it, but I finally had a chance to put the boat on blocks and take a bunch of pictures.
At cruise in calm seas, I find the best performance at 68% trim (indicated via NMEA2000 data from engine and read by Lowrance LMF and Raymarine e-series displays). This is why I included pics at that % trim. When I measured the anti-cav plate, it was at 4º, which is where what I get when measuring the rear cockpit deck. In other words, at 68% trim, the A/V plate is level with the cockpit sole.
However the flat portion of the hull at the stern measured 0º to 1º. Interestingly, at 80% trim, the anti-cav plate is at 0º (i.e. level with the flat portion of the hull at the stern.)
Should the anti-cav plate be level with the hull's planing surface at 50% trim? (in other words, should I have more "negative" trim available?
Also, despite the terrible pics, does anyone have an opinion as to whether the motor looks like the right height? Eyeballing it, it looks like the A/V plate is about 4 to 6 inches above the bottom o f the hull at the stern.
Here are pictures:
at 0%:
At 25%:
At 50%:
At 68%: (optimal "feel" while cruising)
At 80%: (A/V plate level with bottom of hull)
At 100%
