hgg you might clarify what you are trying to achieve.
Don’t let the following discourage you but perhaps guide you. I’m supportive of your quest. At your age I had the chance to sail eastbound and turned it down. A choice I regretted for some years.
You probably want to consider at least three things:
If it is a cheap
way to get home from Europe then probably not the best. You can book a one way flight from Madrid to New York
for $225 (usd). Think about how long it would take you to earn that versus how long it would take you to sail the Atlantic. You would probably spend at least as much getting yourself the minimum gear
as you would simply flying.
If this is about a developmental personal experience or adventure, great. But then put that first and think through what would make this worthwhile or not. If it is about the experience then finding the right boat
and crew probably drastically outweighs which direction you are crossing (it’s only and extra $225 to fly back). A qualified compatible crew in a comfortable well equipped blue water
should out weigh any other decision criteria.
Sailing across the Atlantic in a sail boat is not like calling up Cunard and booking a cabin
on the Queen Mary 2. With a sail boat the schedule is very weather
dependant...in fact you shouldn’t really think of it as a schedule but more a general intent. There is also a degree of seasonality to transatlantic crossings. You might familiarize yourself with Jimmy Cornell’s world cruising routes. Depending on what you mean by “fall” your “schedule” may fall after the typical time for east bound crossings and before the typical time for westbound crossings.
