There is a fellow who owns an A28 from Port Colborne, Ontario, Canada. He has sailed his to the Caribbean and back and used it for as a live-aboard for about 2 years. His only problem that was reported to me was the shortage of tankage for water.
This can obviously be resolved by adding extra tankage or perhaps even a small watermaker, wind generator and/or solar panels.
Hope you enjoy your Aloha 28 as much as I did mine. I sailed mine mostly on the western end of Lake Erie for about 5 years before I stepped up to the Aloha 34. Since that time, I have cruised all of the Great Lakes except for Superior.... it's on the list of things to do.
