We are looking at a 7 night charter from Agana Marina in Croatia on a Moorings Powercat Yacht. We have done this several times in the BVI.

We would need to choose an itinerary for either the Northern Islands or the Southern Islands.

Can anyone provide information or recommendations for one over the other (Northern or Southern Islands), or give your experience if you've been to either?

I haven't gone with moorings, but have been to several of the places. I like the feel of the northern route, but Brac and Jesla are both really good. Stari Grad is next to Jesla, and is a laid back enjoyable town. Zlatni Rat is amazing on Brac, but it looks like the mooring is almost an hour away, which is a bummer.

Bareboat or with a captain?

With a Skipper since this will be our first trip there.

stari grad, vis, brac, korcula, Mljet. You must go to Dubrovnik and sail around the walls. Best view you'll get of that city is from the water.
