2 years ago I began looking at aluminum boats,,, my main criteria was to have a boat that would deliver a good, safe ride in both inshore and offshore waters, and not break the bank for operating costs, I looked at alot of boats, both BC built and US built. I rode in and test drove the 5 that I thought would best suit my needs and budget. I thought all 5 were really good boats, but opted to have an 08 Hewescraft 220 Searunner ht/ext transom built (when our dollar was $1.07 in our favor). From your list I test drove Alumaweld and Hewescraft. We basically boat year round and after over 140 hrs on my package I have been very pleased with the boats performance in the conditions that we operate. In the end, when the budget issues were satisfied, several aspects of the boat's design/performance helped make the final choice fairly easy... just a few of the important ones for me were... soft ride in chop, built in flotation system, heavy duty hardtop with full headroom, and a door to the bow and safe access around the gunnels to the bow, ability to safely handle offshore conditions that we choose to operate in....
Good luck in your search.
