Look at the welds Alweld is hands down better welded, in my opinion far better quality, the price reflects that too. but function about the same. I run some alum and some fiberglass, I do love my 20 ft. glass boat. If going for only one boat, it would be a 1848 Alweld, Tahatsu 25 jet, AND a 9.9 long shaft 2 stroke and interchange as seasons conditions dictate 25 jet jumps it up fine and legal on 11pt. Makes it legal on Buffalo.... One thing I would suggest... Split rear seat, much more comfortable to operate.... and move around, and switch sides.... my 2cents.
