Hey arrozy!
The Isis is a charter ship, this means that people can hire the boat to go sailing but the owner is a fanatic sailor so he compete in these sailing regattas. I for my self work in the summer time as Mate / Deckhand on these sort of vessels and was invited.
Since I work on these sort of boats I am pretty good at seeing what needs to happen when and where, so I do have the overview about the situations. Therefore was I shooting and helping the same time and I found that very enjoyable. In this sort of job it is mayor to see (have an overview) and act... If I see a photo I'll take it, If i see a situation where help is needed I help, If i see that things need to happen, I make them happen :)
you can see the route in the Klipperrace video here at the end. If you want to see a more elaborate route I can produce one for you, just let me know!
all the best, fair winds,
R.
