As others have replied, use a CAD program.
Actual building is more complex.  As I remember, the attackers
at Troy were mariners from an island cluster.   They
would have used wooden boatbuilding techniques.

So, getting back on topic, rent the DVD of Mutiny on the Bounty,
and pay careful attention to the little DVD extra which is a
documentary of the boatwrights making a replica
vessel for the movie production.  You'll need a sharp adze.
