Boat seems to be seaworthy- see above, I would have a professional survey done prior to purchase. Check standing rigging. Keel version seems better. Make sure you are set up for offshore sailing ( all reccomended safety gear including epirb). I am not familar with your sailing route but would you have a safe anchorage every day of your trip to pull into if needed to make repairs or due to bad weather? If the boat has an outboard will it work well in rough seas? Make sure you check long range weather forcast www.passageweather.com
before and during you trip. I would talk to some people who have sailing experience in that area and take them along with you on your trip. Without some off shore experience I would not go alone or with novice crew.
