Yes it is. What I have used is 0.185" thick Meranti plywood.

Once the layouts have been done and the parts all cut out and labelled.

A coat of two parts epoxy is applied on each part individually and allows to
dry. Then the parts are assembled (dry) according to the drawing using the
stitching method. Afterward, the assembly is validated and corrected, as
needed it. After that, the epoxy fillets are applied with fibreglass tape
and let to dry.

Subsequently, a second coat to of two parts epoxy is applied inside out.
Before painting (for UV protection), a third and fourth coasts of epoxy is
applied. As you can see, the construction is light and strong. The
hardwood gunwales and keel also add to the stiffness of the boat

No cloth layed over the panels, just at the seams? Seems like a waste
of resin, if you were going to put on two coats you might as well have
put on some cloth which would improve strength & abrasion resistance.

Foam core would have been lighter & stronger; I've seen a number of
tenders & dinghies built using 4mm and 5mm plywood and that's what
convinced me to use foam core.... those boats you have to step very
carefully in & out of.
