If you look at previous vidoes on this boat you can see the hull on stands. Whether a hull is planing or not comes down to the "Quarter beam buttocks angle" This is basically the center half of the bottom boat if divided into quarters as it meets the stern . If this angle is flat or only slopes up very slightly towards the stern, the hull can plane, if the slope is more than say 5 to 7 degrees, the hull will more efficiently ride its own wave, but at a cost of not being able to plane. Think of this back part of the boat as the trailing edge of a wing, if its angled up, the boat gets sucked down more and more the faster it goes. Think of the shape of a racing sailboat, how curved upwards the stern is. This vessel has a pretty flat tail end underneath, and it definitely climbed onto plane. Didn't plane fantastically, it was nose up, but it planed.
@@SeaboardMarineIncVideos it's a semi displacement hull. Like a Novi or Maine lobster, I'd rather be running 10-12 knots in some serious slop in a semi displacement hull, very comfortable, you'll beat all the deep v boats into port.
@@SeaboardMarineIncVideos build down not a skegger! Like a Lowell, flowers, Duffy. Mines a wesman kinda a new breed strange combo of Chesapeake and built down Maine hull. Nice boat, it a definite keeper. Heavy as shit for what it is.
No the hull is not steel, it is fiberglass. The reduction and propping was pretty close. He could actually use a bit less prop, wasn't quite hitting the governors.
So the 210 JD,s would not go past 1500rpm , so certainly over propped for that engine. Now you add 100Hp to each engine and you get respectable performance, and fuel burn. In reality it has nothing to do with the brand name, but the level of power and technology. The John Deere dealer is likely doing the same, jerking out mechanical 6B, 210 hp and putting in new 6068,s. Having said this the Cummins and JD,s are both great American engines, certainly my choice over the Swedish and Japaneses engines.
I have the 13.5L at 600hp in my wesmac and love it, it's all about the prop after you know you have a great engine. I couldn't tell if this was a fiberglass or steel.
glendinning vs zf controls. pros/cons of each?
What's the typical break-in procedure for the new Cummins QSBs, if any?
What make of boat is it nice job people
Not sure why he insisted on bumping up throttle on engines separately each time ? any insight
How much do you figure the struts surrounding the propellers and rudders slowed you down?
That's more a question for the owner. We never saw the boat run without the gear so it would be hard to make a guess.
Despite what the owner says, it doesn't look like a planing hull to me. Maybe semi displacement
It planed at 21 knots with 620hp. Definitely a planing hull.

Is that boat steel? Not a huge boat, does he have to much reduction gear?

Next time you touch the shaft or coupling shut the engine down first
