Did an accelerated course in the British Virgin Islands with these guys

Did ASA101 ,103 and 104 in 5 days live aboard , second week we chartered a boat ourselves and sailed around the islands (we took a local skipper).
I think technically this qualifies me on paper to day skipper.
The course was extremely tough , requiring a bunch of theory to learn beforehand , written exams every morning. Physically quite tough as we sailed from dawn to late afternoon with lots of course changes and man overboard drills. Then you had to chart and skipper a leg at the end yourself with a man overboard drill chucked in without warning.
It was tough but great fun and the BVI was paradise to sail.
Alas I have been too busy to sail since but I still hanker after it.
