To limit boat issues I always get the Exclusive Plus boat (less than 1 year old) and always do a sleep aboard the night before. To afford it I always go non peak and share with a second family. If still tight we do more eating (and drinking) on board. Most issues will appear during the evening start and can thus allow ample time to be addressed. Non peak also has the advantage of if your not happy with the boat another would be available. The evening start also takes the stress out of getting to the marina and leaving at a reasonable time and also allows for provisioning for those items you forgot or where not available at Moorings. Had a nice breakfast at marina and was off the dock by 10am. Stress is the last thing you want on vacation. I also do Emerald day before and day after charter. No worry about making ferries.
