Kind of a catch 22, typically Apache uses 8' beam, and O.L. uses 8.6", A.T. uses 8.4", ride and safety is more important to me, also depends on whether its a notched transom, pad, 1 or 2 steps or now even 4 steps, and how good these steps work with the various bottom designs. Anything over that 40' range I prefer 8'6" to 9'. Just my .02.
Which boats are you trying to compare, thanks
