|Alumacraft all-welded tiller jon boats are the standard for durability, workmanship and performance. These hard working, no-non- sense boats are built on Alumacraft's legendary all-welded hull; reinforced with heavier, wider and stronger ribs. That makes the entire jon boat stronger, more rigid, and extremely durable. You'll find outstanding workmanship and heavy gauge construction the entire length of the boat. Back it up with a reliable outboard and put that boat to work. Tunnel hull models are available in all sizessee your dealer for details.
