Perfect loading of the boat is with the Center of GravityCenter-of-Gravity (CG)Center-of-Gravity (CG)The center-of-gravity (CG) is the point at which a boat would balance if it were possible to suspend it at that point. It is the mass center of the boat, or the theoretical point at which the entire weight of the boat is assumed to be concentrated. equally spaced Bow to Stern and Port to Starboard.

Typically it is necessary to move the Center of GravityCenter-of-Gravity (CG)Center-of-Gravity (CG)The center-of-gravity (CG) is the point at which a boat would balance if it were possible to suspend it at that point.

Results will determine if lift capacity is sufficient based the weight distribution of the boat based on the boat’s positioning on the lift.

All results are approximate and it is the owners responsibility to determine where the CG is positioned on their boat. For most boats this requires a call to the manufacturer as it is not listed on the specs page.
