The way I figure...we need a big family tow boat for the river and Havasu. The S22's almost perfect for that. But back home, we pretty much need a towboat.
What you've got here might be the perfect boat for a small crew. Three, four guys, ballast, a 4 gph engine and a narrow beam good for sinking way down there. Hope we win the lotto before all the good E21's are gone.
