It is the body's added mass.

I may be confused, but why does it have 3 different components? The z-component of the PVector is used to calculate the new ddotphi in the rotational dynamics, what is that accounting for?
ddotphi = M + ma.z*ddotphi/(I0 + ma.z);
I don't see the need for it in my equations, so I'm wondering if I am missing something.
Why are both the moment of inertia calculated from Body getArea() and ma.z needed?
Thanks for the help.

Apologies. It is the added mass. The linear inertia due to accelerating the surrounding water from translation in x or y or rotation around z.
