CG?????

[phase]

hi
i have browsed around for i while on this forum and i seen that alot of people ask "where is the CG on this boat?"

what does tha mean..
is it center of gravity? and how can you adjust it?

[RMZDADDY]

Yes, it's center of gravity. I move the battery packs toward the bow or stern to achieve the correct CG in my boats.

ok so if i have my packs in the middle it would be CG=50%?

[RMZDADDY]

That depends on the placement of the other components in the hull. The way to find the CG is to find the hulls balance point. I just lift the hull with one finger on either side to do that.

so basically you find a balance point and then adjust from there?

[RMZDADDY]

The balance point tells you where your CG is. Different hulls need different CG placement for the best performance. I started with the CG on my cat at 30 percent and fine adjusted from there, based on what gave the best speed and handling.
To find the percentage I take the balance point distance from the stern and divide that number by the total length of the hull, 8.75" divided by 29" = .30, or 30 percent.
Hope this info helps.

ok thanks i think i understand now..

Some of the guys here can tell you a good CG starting point for just about any kind of hull, I know I've learned alot here
