If your talking about just top speed and no other considerations I think a Flyer is going to be hard to beat, it's big enough to hang a good sized motor on and has the faster hull design of the angled chines and short planing bottom.
The bigger boats may be able to produce speed with enough power but the round chine hulls and long wetted bottoms are going to take a lot of power to produce speeds above 45 MPH.
The early runabouts are light and long but I don't have any idea of how well they would handle at higher speeds.

Thought I’d start another thread since I don’t want to high jack to 2020 Arrowhead post.
What is the best FC hull candidate for performance?
Rangers seem to be heavily built for their size.
Back story: Been always fascinated with performance since I,was,a,kid,with go,karts, started racing karts in 1958, have taken motorcycle and car (SCCA) license school. Have done mostly high speed lapping days with karts, cars and motorcycles. Been fascinated with boat performance for a long time. Have a tunnel hull with big Merc clocked at 105mph.
Had a firefly with a KG7. Had a Yomato for it but never ran it. Had KG7 on a 1948 Runabout. now have the 1948 Runabout with a Merc 25. Building the Merc 100/Deluxe Clipper now, consider repowering my present Runabout.
