Called chine walking to be specific. I find with hydrofoil it minimizes it. That was what I referring too.
I am just trying to help the guys that originally posted out.

My little 16' Lifetimer CC came with a dol-fin and I've left it on.
The boat rides very nice with a Yamy 50.
Had not reason to remove it.
For my Hewes... I don't love the idea of adding a dol-fin....
....and drilling my anti-cav plate
but if I knew it would solve all my troubles I would do.
My Hewes has these Nauticus Smart Tabs, which are 'passive' trim tabs, ..... which don't seem to do much
My problem is really is due to weight distribution I think,
A heavy Yamy 150, with a heavy 9.9 big foot Merc, and dual battery, and a radar arch.
I'm loaded !
I've torn into the foam in the last few months,... just the bottom 1 inch of foam is wet, but the rest is dry.
So I'm not carrying 300 lbs of water on board.
I don't like the foam from a corrosion point of view so its coming all out.
The sand bags in inner tubes do help a fair amount, but its a band-aid until the weight distribution can be fixed.
One day I could relocate the dual batts to under the stairs to the bow
I have an aluminum welder (spool gun) now.
I appreciate everyone's input
As is I cant use all the power in my big 150, above 22 or 24 knots it starts to porpoise, but I have a lot more motor still.

I've checked this early on while underway and in the driveway, and motor height is perfect

Let's put a 4 stroke 150 on a tin boat that's 18ft. Then throw a kicker on it. Whatever else. That boat has waaay too much weight in the back. Multiple reasons
Naaw, toss a fin on it lol

Why Do Boats Porpoise? All Of The Reasons You Need To Know About - Born Again Boating

The poster never got back for a result on is the bilge wet. Is the foam wet. ? Those hulls Crack in the keel all the time. It's built with 2 halves, with an excruded piece of aluminum to join. That boat is over powered with a very heavy engine.
The problem is right there.
The problem is right there.
I’m thinking to get the balance right, he needs to remove the 150 and replace it with a 115 or Zuk 140 and probably still move the batteries forward. It’s a lot of work but I agree, just too much added weight in the stern for a light aluminum boat.

Yessir, pretty sure you nailed that one
I'll bet with the batteries and all the stuff he's almost 700lbs at the stern

not yet, but I've heard others suggest that also.
I have a turning point prop / hub, so I can swap props for less cost

the 150 has an advantage of less fuel consuption, the motor is barely breaking a sweat, operating in an efficient rpm, and not strung out.
3600 -3800 rpm has me flying as you might imagine lol
