Hey Jessica,
I still consider that week the best ever--I'm sure it would be a wonderful as a 30th bash! We used Sail Croatia (http://www.sail-charter-in-croatia.com/) and Ozren was our skipper/chef. Highly recommend hiring a combo skipper and chef, the eating experiences and easy logistics made it all the more magical.
When you reach out, ask them to say hi to Ozren and Ivana from Marguerite Hancock and family from California--my mom has referred many friends :)
Good luck!
Channing
