I just completed a 2 week "shared expense" split charter on a Skye 51 from St. Lucia to St. Martin. The cost was 50 GBP ($71 US) per day. It was the best vacation I have ever been on and we usually go to 5 star all-inclusive resorts.
Can you post the details on how you accomplished this?! What charter co's, what was the condition of the boat, etc....
