  We present a new weak lensing analysis of the Hubble Frontier Fields galaxy
cluster Abell 2744 ($z$ = 0.308) using new Magellan/MegaCam multi-band $gri$
imaging data. We carry out our study by applying brand-new PSF and shape
measurement softwares that allow for the use of multi-band data simultaneously,
which we first test on Subaru/Suprime-Cam $BR_cz'$ imaging data of the same
cluster. The projected total mass of this system within $2.35 \, \mathrm{Mpc}$
from the south-west BCG is $(2.56 \pm 0.26) \times 10^{15} \,
\mathrm{M}_\odot$, which makes Abell 2744 one of the most massive clusters
known. This value is consistent, within the errors, with previous weak lensing
and dynamical studies. Our analysis reveals the presence of three high-density
substructures, thus supporting the picture of a complex merging scenario. This
result is also confirmed by a comparison with a recent strong lensing study
based on high-resolution JWST imaging. Moreover, our reconstructed total mass
profile nicely agrees with an extrapolation of the strong lensing best-fit
model up to several Mpc from the BCG centre.
