No problem - I found your post very informative.
I may not go to Africa, but I probably won't spend all of the next 10 years circumnavigating the Virgin Islands either.
I want a sturdy, solid boat about 34-40 feet, with ample fuel/water tankage, and comfortable enough to live aboard and on the hook as much as I can stand.
Beyond that I'm not likely to try to fit it with all the gadgetry that I might need if I were planning a solo sail to Africa. But I think there are probably some items, such as an autopilot (or wind vane) and self-tacking staysail that might be considered 'standard fare' for single handing such a boat - even if I were to stay in the Caribbean.
