  In response to stringent emission reduction targets imposed by the
International Maritime Organization (IMO) and the European Green Deal's Fit for
55 legislation package, the maritime industry has shifted its focus towards
decarbonization. While significant attention has been placed on vessels
exceeding 5,000 gross tons (GT), emissions from coastal and short sea shipping,
amounting to approximately 13% of global shipping transportation and 15% within
the European Union (EU), have not received adequate consideration. This
abstract introduces the Zero Emission Sea Transporter (ZEST) project, designed
to address this issue by developing a zero-emissions multi-purpose catamaran
for short sea route
