I run most of the time with my trim at 25 - 30 % thats where my calvitation plate is parallel with the keel and running bottom of the hull checked with a straightedge. But I am still playing with the prop and the height of the motor, may raise it another inch. As soon as you trim it up a touch the prop wash cleans right up. Being able to trim it down lets me slow down in bad conditions to 10 to 12 knots and drop the bow in a little and its easy peasy all the way home(thats where the spray rails will help) on a nice day you can push the throttle to 22 - 25 knots and trim up and raise the bow a little and it runs like its on railroad tracks , dead flat and you drop the hammer trim up enough to just see the rooster tail showing up drop your sun glasses down on your nose and smile as you pass buy some of your buddies and you know your running right just from the look on their face's and the next time you see them most of them all have the same question. What kind of boat is that again ! Most of the time I run around the 19 - 20 knot range and overall I can change the running angle( bow height ) of the boat by anywhere from 12 to 18 inches depending on wind and conditions but its usually in that 25-30% trim range when leave the dock and I dont need to change it all day. Like I said spray rails and quarter guards will be in the future and also thinking of what a set of lifting rail may do but I am still waiting to get a good close up video of the hull running at cruise speed.
