Fair point on the long sail. Someone said it earlier, but the sail from Cooper up to North Sound can be a good long one. And never forget that you can make any of the island hops as long as you want if you just keep sailing I would 2nd Marina Cay. We always enjoy it more than we think we would. Don't neglect to snorkel the reef there- always surprises with some cool stuff. Similar to you, we are monohull sailors at home, but always look forward to the Cat (also a 44 usually) when chartering. Enjoy the trip.
