We also own a a 49rph, a '79, twin leman 120's.
With that hull 120's are plenty and the high bow is comfortable to have. We will often on calm days here on the Chesapeake shut one down and freewheel the prop (don't mean to start up that conversation) and with @200rpm more on the running engine do the same speed ( 1750-1800 = @ 7-7.5 kts)
The high bow does come in handy for those storms coming from the NE and we have to get somewhere.
We weigh 54,000 lbs and draw 4.5 ft.
Love the boat.
