I think I have identified a flying wing phenomenon with my T-Top. Which BigShrimpin noted is " a beast"...
It affects the trim with two people in a way I didn't anticipate when I don't run with a kicker. I finally have enough weight forward- between passenger, t-top and forward fuel tank and cooler. So that now the boat is slightly bow heavy when I don't run with a kicker.
I have a 4 stroke F100 at 370 lbs, BTW.
So equipped like this, I tend to trim the outboard (with flying wing/ hydroshield, and stern lifting prop) to lift the bow a bit at cruise. But as I speed up to WOT, I can trim up the outboard to the point of blowout. edit: (and that's new. I never used to run like that- it was too bow high/ squatting)
The weird thing is- the boat flattens out dramatically. As in, I am trimmed up to blow out, and the boat is running flat. I think the t-top with the downward bent nose doesn't do that much at cruise, but as the bow lifts and it speeds up it becomes a fabric cambered wing and lifts the stern out of the water. Only above 25 mph. But the hull dries out dramatically at WOT. To the point that the ride gets a bit harder, as there it too much lift, so the chop can get jarring. It is really strange. With more weight than when I run singlehanded, it has a harder ride. I think it is a subtle dynamically unstable trim issue. Partly because now with no kicker, it is a bit more prone to porpoise at 19-20kts. I was going to wear out the OB trim pump experimenting how to reduce it yesterday off Plum Island.
I am going to start putting the cooler in the stern now, that should help. Although this is a dynamic trim issue, so maybe getting rid of the hydroshield or going to a 3 B non stern lifting prop is really what I want.
It has taken me a few trips with passenger at WOT and no kicker to figure it out. It is fine with the kicker and passenger. Or kicker singlehanded.
