Diego Melas

 

I'am on the sea for over 30 years.

My job as a pleasure boat captain is very rewarding because it allows me to share my love of sea on the water with others.

 

It was a pleasure for me realize this site. This is my attempt to make teaching a modern and friendly job with ancient methods by keeping upto date with today’s world. I am open to suggestions, criticism and more, for improving process of teaching/learning.

I hope to become a point of reference for future generations and a refresher for the more elderly.
