Sailing Trip Cartagena

We are exploring organising a 3 day, 2 night sailing trip starting and ending in Cartagena. We are currently 4 people and are looking for 1 or 2 other couples (happy for singles but we aim to split the boat based on rooms, the boat has 4 double beds). Price would be $500us per couple for four couples not including food and drinks. We would need to self cater and ideally we would like to be cooking together (two of us are vegos). Aiming to depart on the 26th of August. If you are interested please get in touch! We are keen to enjoy a few days sailing around the Caribbean coast and islands of Colombia, snorkling on beaches and enjoying a few drinks on deck. We are from Australia, aged 29 and 27 and have been travelling for 5 months in South America. The other couple is from Britain, similar ages and have been traveling for a similiar amount of time.
