Agree with LTD on ASA 104, 05 & 06. Then charter
a few different brands, expensive? Yes, but may keep you from making an even more expensive mistake later.
Search and you may find a group that is "one cabin" open and wiling to sell that cabin
for a quarter of the charter
costs. Cheaper way to charter and great way to make new friends. You would also benefit, hopefully, from their sailing experience.
I honestly have no idea how you would vet the group tho.. They may be good or they may be not so good.
