This is a solid, compact scene! Two characters are developed with a healthy dose of "show" vs "tell."
My spoon was made of cast iron.
Excellent little detail that really rounds off the protagonist's plainness.
His finger traced over the drawing, no doubt his mind trying to comprehend such a creature, swimming in some distant ocean somewhere.
I love the way it ends too. You avoid a classic head-hop by including the words 'no doubt,' which keeps us firmly in The Captain's POV.
