Thank you very much for your great advice. For the past year or so I have been watching different videos on YouTube as per your suggestion, and they are indeed a great source of information for one to digest. Regarding the size of the boat, at first I was set on a Valiant 40, not just because many experienced sailors were on a boat about this size, but I have since convinced myself that a boat in the range of 31 - 34 is probably the better way for me to start. That is exactly the reason why I was seeking for first hand knowledge on the 31 Independence. Given my first priority of safety, it appears that the keel and rudder of this model Ericson checks that box quite well. However, as I do not first hand experience with this or any other boat, I am seeking to lean for advice from those that have an intimate working knowledge of this specific boat.I'd suggest you watch some of the longer running (multi-season) YouTube channels by solo sailors and couples that are devoted to long distance cruising. Most of them have at least one episode devoted either to the pros and cons of their current boat's suitability to bluewater voyaging, or to their view of the features that are recommended for the task. These people interact with a lot of other cruisers, who are always comparing notes on what works and what doesn't. There are a LOT of variables you have to consider, which can be narrowed down by your own plans, budget, experience and research.
If you are going to sail solo, or with just one other most of the time, do not get a boat that's too big (even if it seems like an irresistible deal): if you're mostly solo, look at boats less than ~40'. The bigger the boat, the more complex and expensive to maintain will be its systems, and, ALL your repair/replacement costs will be MUCH more with every step up in size.
As someone else said, you might want to get a cheap starter boat first (~28-30' max; with an inboard engine) and start doing some coastal multi-day trips. If you get it for a good price and you fix it up a bit over your first year, you can probably recover your costs when you sell, and put those $$ toward your bluewater boat.
Good luck as you go up this learning curve.
Notwithstanding, I recognize that there is no substitute for personal experience and hence the adoption of the "just do it" approach.
Greatly appreciate your words of wisdom,
Ron
