kwaltersmi, you seem like a sincere person and a lot of the posts reference a lot of good boats but really, with an itinerary going around Cape Horn you can't be serious. If that is a criteria, none of these boats fit it. If your plans are to go island hopping to the Bahamas down to the Virgins most all of the boats are good choices.
Otherwise your offshore trips require a lot more boat. Small kids might have a hard time when you get caught out which undoubtedly you will. Best suggestion is to try to get a crew position in the Caribbean 1500 rally held every November.Make the trip and then decide what your needs are. My bet is that your boat choice will be a lot different. Offshore Passage Opportunities â€“ Volunteer Crew
Try to find a 35-39 foot Amel. Built in France and renowned for being well thought out world class cruisers. Hard to find in the states and styling is unique but hardly salty. A month in the tropics and you won't want to maintain the teak of a salty looking boat.
