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.
Cheers,
Larry
