Did my first offshore cruise at 60yo, from Dominican Republic, Atlantic side, to NZ. Just me and a never sailed before traveller, had a great time, auto pilot broke a week out of Panama so steered the rest of the way. My navigation was an Ipad with gps and a cheap app that was the most accurate system ever used. An older 40ft cat so had a few issues but all manageable. If you can sail and have some brains just pick which way you want to go and do it. My one and only time and I will never regret it, a dream fulfilled
