Simple...... GRavity is a force. TRy jumping off the roof and floating... you dont, you go splat. Gravity is the force making you splat.

Balance,,, Finding equilibrium, I am going to balance the rotating assembly, I am going to balance on one foot its an action, it something you do to something

Had twin 300xs Merc outboards on my 30' v hull after side by side BBC with TRS using Stainless Marine bracket and hydraulic Jack plates. Saw no difference even when at dock. Handled pretty much the same . Aprox 12-1300lbs on back vs more forward and inside work s out . They didn't change hulls or construction much on all the hulls over the years that offered both power options.

That is a great example! Thank you

i thought it was the sudden stop on a hard surface that makes the splat.

is this a winter thread or is it for real

what is good balance front to back ?

how much movable weight, and how far do you move it ? i have 3 permanent places to put a battery, front- mid -back roughly 4 and 5 feet apart and all the way down in belly a few inches above the keel
when you go weight forward for balance what are you looking for 30 -40 percent loa from transom as example.

I'm serious, and it is winter so I'm a little bored. I'm sure to some it's winter and there goofing around. I read some articles by Michael peters that i'd like to find again, they would do a scale model and divide the boat into 10% sections over length. They would then judge the boats speed and handling capabilities based on the number they got from the weights over the length.

I get that part. So are we debating the term center of gravity and it should be center of balance LOL. I only know it as CG in the boating world but doesn't mean it right.

We have 180 lbs we add about 4' ahead of the helm

I think it only matters if you're running a stripped out race boat.
Once you put people and gear in a boat, the 'centre of gravitance' will alter but it's not significant. How else could a manufacturer justify building a closed bow version and an open bow version of the same boat?

It probably makes a bigger difference when trailering and the amount of weight on the tow hitch.
