If you want deep vee big water aluminum take a look at the Duroboat. It is a boat that was built in the northwest but is now in the east. They have a 16 that is very light. It isn't welded or riveted. It goes pretty fast with 30 or 40 HP and can take rough reservoirs. The boat is very light very simple to work on and easy to customize. Lots of examples and some weird fish at their website. One of the 16s went 6000 miles driven by two girls. Most used ones are on the west coast but hard to find and hold their value.
