Again, take a test ride... Drive it like you stole it!!!! If a sales guy is stating this or that boat is the best, make sure they'll let you drive it hard- in crappy conditions as any boats rides nice in clam flat water.... . If you want a great alum boat ride, come and ride in my Wooldridge Offshore, not many alum are going to ride even close as smooth. Except Buckhorn's sweet ride!!!!! Or a 28 Duckworth with 350 - drool......
Granted mine isn't a plastic boat ride, but for an Aluminum, I have not been in a smoother riding 23 ft metal boat with 225 Honda... No manufacture installed suspension seats for a reason.... lol... I like Aluminum as my motto is - "Docks Fear Me".... Besides for the same size boat, alum is lighter to trailer, easier on fuel, less HP for performance and easy to take care of... But you do sacrifice ride difference. It all depends upon what is best for you... Get the biggest motor you think you need then add 50hp... As there was a need this year in my boat for those extra HP - Buoy 10 when the weather got bad and we cross the bar slightly later than we should have- extra power was calming coming out of the bottom of waves!!!!

Under powered would have sucked really bad!
Can't drive fast in most salt, but sooner or later it flattens out and you want to put the hammer down and run in.......

I agree with Gasman, those River Hawks looks like the welds were done by me, and I do not weld!!
