CG Location Calculation
 

Is there a service or does someone have a formula for finding CG ?

Procedure includes weight of loaded trailer trunnion (axle centerline on single axle, equalizer on tandem and centerline of center axle on triple axle) and weight of the tongue jack. The jack weight and trunnion weight are separate individual weights and found one at a time. The two weights are then added together to find total weight of loaded trailer.

Measurements are then taken, trailer ball coupler to trunnion, boat bow tip to trunnion, overall boat length, trailer overall length.

Empty trailer is then weighed using same procedure used when trailer was loaded (trunnion and jack separately).

Some believe the CG should be located relative to the aft step on a stepped hull.

What would be a fair price for such a service ?

why not just CG it?

Hey guys,
I don't know anyone who does this work nor do I have any experience on which to base the price.

Sean, What boat is that ?

We tried doing that, I guess the floor wasn't level. The boat rolled through the wall, down the street, into traffic and didn't see it for a week. When it finally came rolling back it was hung over and looked like it had even been in a brawl !! Some lady HUH ? :boat:

John, your welcome to send us the numbers, gratis.

Yes, flat concrete is a requirement for putting it on a roller. :drink:

now i dont care who you are,THATS FUNNY CHIT.:lolhit:

Want a science project ? Try doing the overall C.G. which includes vertical and horizontal axis plus centerline offset.
We did this once with a 62 ton Army tank !
Loadcells, overhead crane and rotating pivot plus many H.P.calculators ( pre-laptop/P.C.)

Thanks!

I'm completely lost. I thought CG was Coast Gaurd. I was trying to come up with an alibi ( i'm sure i spelled alibi wrong ).
